Top UptimeRobot Competitors & Alternatives in 2026: Feature & Pricing Comparison

If UptimeRobot says your app is up but customers can't use it, check what your monitor is testing before you replace it.

An HTTP check can fetch the dashboard's HTML without running the JavaScript that renders it. An API can return 200 OK with an error in the response body. And a backup job can fail without affecting the website at all. You need a different check for each of these.

UptimeRobot's paid plans already support JSON assertions, regional checks, and heartbeats. If you're missing an assertion, add it. If you need to test a browser interaction, run an existing Playwright project, or change how your team handles on-call, you'll have more reason to switch.

Below, I compare six alternatives, including their browser runtimes and the cost of two small-team setups. There's a Playwright and Terraform example you can adapt to your own app too.

OnlineOrNot is a good fit if you want standalone Playwright checks alongside uptime monitoring and status pages, especially when you manage infrastructure with Terraform. Checkly supports larger Playwright projects; Better Stack and Hyperping include on-call features. For self-hosting, look at Uptime Kuma. If your logs and traces already live in Datadog, its synthetic tests can save you switching tools during an incident.

I build OnlineOrNot. This comparison uses vendor documentation and prices checked on October 1, 2026, plus our scheduling and pricing code. The HTTP and browser examples have local checks behind them; I haven't benchmarked all six vendors' alert speed.

What does UptimeRobot already do well?

UptimeRobot offers hosted monitoring with HTTP, keyword, ping, and port checks, plus a mobile app and public status pages. Paid plans extend that coverage to API responses, DNS, UDP, certificate and domain expiry, heartbeat monitoring, and location-specific checks.

Its API monitoring supports JSON-field assertions with all/any logic, custom requests, Basic/Digest auth, and JWTs in headers. OAuth2 support is still in development according to that page, so don't assume it will refresh an expiring token for you.

The regional-monitoring docs describe rotating checks across selected regions, then confirming a failure with multiple nodes in the affected region. You can set regional response-time thresholds and receive a region-specific alert.

You can use those features for production monitoring without changing providers.

UptimeRobot pricing and plan differences

The pricing page showed these EUR prices when checked. Your local prices may differ.

Plan	Price per month	Monitoring	Team access
Free	€0	50 monitors; 5-minute checks	No extra login seats
Solo, entry tier	€10 monthly; €9 with annual billing	10 monitors; 60-second checks	No extra login seats
Team	€41 monthly; €35 with annual billing	100 monitors; 30-second checks	3 login seats included
Scale, entry tier	€77 monthly; €65 with annual billing	200 monitors; 15-second checks	5 login seats included
Enterprise	Custom	Custom limits and intervals	Confirm with sales

Solo also has a 50-monitor tier; Scale has a 500-monitor tier. Extra login seats on Team and Scale are paid add-ons. Login seats and contacts who only receive alerts are separate allowances.

Status pages are already part of UptimeRobot: Solo includes three with custom domains, Team includes 100, and Scale includes unlimited pages. Subscriber notifications and password protection are available on Team and Scale.

I'd keep UptimeRobot if its checks cover your failures and you use the mobile app or need lots of status pages. Its 50 free monitors and Scale's 15-second checks are also hard to ignore. The alternatives below make more sense when you need browser scripts, different team pricing, or a different deployment setup.

UptimeRobot competitors at a glance

Start with the row that describes your setup, then check the limits in the product's section.

Competitor	Useful for	Starting price
OnlineOrNot	Software teams wanting uptime, browser checks, cron monitoring and status pages together	Free Hobby; Pro from $25/month
Better Stack	Teams that want monitoring plus incident response	Responder from $34/month
Checkly	Code-first synthetic monitoring	Starter Detect from $29/month
Uptime Kuma	Self-hosters and private infrastructure	Free software; you operate the infrastructure
Hyperping	Lightweight uptime monitoring and status pages	Essentials from $29/month
Datadog Synthetic Monitoring	Enterprises already using Datadog	API and browser execution rates plus incident-management operator licenses

Pingdom and StatusCake are other options for website monitoring; our tools guide covers them.

First decide what your check needs to prove

Pick the check based on the failure you want to catch:

Failure	Check that can detect it	Check that can stay green
Origin returns 503	HTTP check with expected status	A check that deliberately accepts 503
API returns 200 but database is unavailable	Assertion on the dependency field	Status-only HTTP check
HTML loads but client-side results never render	Browser action plus rendered-content assertion	HTTP check on the HTML shell
European customers cannot reach the CDN	Check from Europe with an appropriate incident policy	A healthy probe elsewhere
Backup job never finishes	Heartbeat sent after successful completion	Heartbeat sent when the process starts

A 200 OK API response can still need an alert

Suppose /api/health returns this with HTTP 200:

{
  "status": "ok",
  "dependencies": {
    "database": "unavailable"
  }
}

Set the assertion to $.dependencies.database equals ok. Checking the top-level status field would miss the database failure.

OnlineOrNot supports JSONPath body assertions, along with header, text-body, and HTML-selector assertions. UptimeRobot supports JSON-field validation too, so either can catch this once you configure it.

A JSONPath assertion in OnlineOrNot's editor. Use the property field to select the value you want to check.

A browser opening a URL is not enough either

A browser can load /catalog successfully while the “Show products” button does nothing. Click it in the script and check that the results appear.

For the local example, both versions returned HTTP 200. One rendered results after the click; the other threw a JavaScript error in the click handler.

Controlled example	Status-only check	Check of the intended result
Working catalog	Pass	Pass: results heading becomes visible
Broken results renderer	Pass	Fail: results heading never appears
Unavailable database in the JSON above	Pass	Fail: dependency value is not ok

The Playwright example below checks for the results heading. A navigation-only script would pass both versions.

Regions, retries, and alert timing are different settings

If you need an alert when European customers can't reach the app, check the regional schedule and failure policy. A vendor advertising “30-second checks from multiple regions” may rotate probes rather than run every region every 30 seconds.

Read the retry policy too. A second probe in the affected region can confirm a local failure; a successful retry elsewhere can tell you that the problem isn't global. Then check how long the failure must persist before the tool alerts you.

How often does each region run?

UptimeRobot rotates through selected regions. OnlineOrNot also selects one region per scheduled run; our scheduler avoids the previously used region where possible.

Suppose three regions take turns at 30-second intervals. An even rotation would revisit Europe every 90 seconds. Neither vendor promises that exact schedule, but it's why you need to ask about the cadence per region.

UptimeRobot confirms failures within the affected region, which helps when Europe is down but North America still works. OnlineOrNot uses cross-region verification to reduce transient false alarms. If a failure in one region must page you, test that behavior with a region-targeted check before switching.

When does a failed check send an alert?

OnlineOrNot's confirmation period lets you wait before declaring an incident. Its recovery period delays the all-clear. This helps when a service briefly comes back, fails again, and otherwise fills your alert channel with up/down messages.

Three minutes selected for confirmation and recovery. You can change both.

For example, with 30-second polling and a request that fails after five seconds, an outage that starts just after a poll could take about 35 seconds to produce the first failed result. A 60-second confirmation period adds more waiting before notification, as do retries and delivery delays.

Use the same confirmation settings when comparing tools, or you'll mistake a difference in alert policy for a difference in speed.

1. OnlineOrNot: for production software teams

OnlineOrNot handles uptime, API, browser, and scheduled-job checks in the same account. Pro includes unlimited team members and a public status page with a custom domain and unlimited email subscribers.

I'd put it on your list if several developers need access and you want to manage the monitors alongside your infrastructure. Our Terraform provider supports checks, heartbeats, status pages, and alerting resources, including Playwright checks.

You can send failures to the team's existing alert channels or on-call tool. OnlineOrNot doesn't replace the rota and escalation rules in PagerDuty; Better Stack and Hyperping include those features if you're looking to buy them too.

A browser check you can keep beside your infrastructure

Here's the catalog example as a standalone Playwright file. Replace the URL, button, and heading with a read-only path in your app.

Save it as catalog.spec.js:

import { test, expect } from '@playwright/test';

test.setTimeout(30_000);

test('catalog returns products', async ({ page }) => {
  const response = await page.goto('https://example.com/catalog');
  expect(response?.status()).toBe(200);

  try {
    await page
      .getByRole('button', {
        name: 'Show products',
        exact: true,
      })
      .click();

    await expect(
      page.getByRole('heading', {
        name: 'Available products',
        exact: true,
      }),
    ).toBeVisible({ timeout: 10_000 });
  } finally {
    await page.screenshot({ path: 'catalog.png' });
  }
});

toBeVisible() waits for the heading, so you don't need a fixed sleep after clicking. The finally block saves a screenshot even when that assertion fails. OnlineOrNot attaches screenshots saved with page.screenshot() to the run output.

To deploy it with Terraform:

terraform {
  required_providers {
    onlineornot = {
      source = "onlineornot/onlineornot"
    }
  }
}

provider "onlineornot" {}

resource "onlineornot_browser_check" "catalog" {
  name          = "Catalog returns products"
  script        = file("${path.module}/catalog.spec.js")
  test_interval = 300
  test_regions  = ["aws:us-east-1"]
}

Set ONLINEORNOT_API_KEY for the provider. Terraform reads the script file and configures the monitor to run every 300 seconds in aws:us-east-1. The deployment guide covers testing locally, selecting a provider version, and deploying.

Keep the resource address stable when updating the script; Terraform will update the existing monitor and keep its history. If someone edits the script in the dashboard, the next plan can show that drift. Be more careful with filename-based resource keys: renaming a file can plan deletion of the old monitor and creation of a new one.

What you can upload

This Terraform workflow uploads one self-contained JavaScript file. It won't upload local imports, npm dependencies, or your playwright.config project. The script must contain valid JavaScript and finish within the 120-second service limit.

OnlineOrNot's organization environment variables currently work in uptime-check headers and Basic Auth, but don't work in browser scripts. A local process.env value won't appear in the remote run either. Don't put a real password in the script: Terraform stores it in state and can show it in a plan.

For independent browser checks, this setup is easy to keep in the same repository as your infrastructure. If you need shared fixtures or custom packages, look at Checkly's suite support. Hyperping documents browser environment variables if that's a requirement.

OnlineOrNot pricing

Pro starts at $25/month for 35 monitors, 3,000 browser runs per month, one public status page and unlimited team members. Additional monitors, browser runs and pages cost extra. See current pricing.

One browser check every five minutes schedules 8,640 runs in a 30-day month. Selecting three regions still schedules one execution per cycle; creating three separate monitors schedules 25,920 runs. The pricing examples below show how the run packs add up, before retries and manual runs.

OnlineOrNot vs UptimeRobot

Requirement	OnlineOrNot	UptimeRobot
Body correctness	JSONPath, header, text, and HTML assertions	JSON-field assertions on paid API monitoring
Browser interaction	Standalone Playwright journey	No scripted browser type in reviewed catalog
Regional execution	One selected region per scheduled run	Rotation through selected regions
Failure policy	Cross-region verification; configurable confirmation and recovery	Documented confirmation within affected region; regional alerts
Team dashboard access	Unlimited on Pro	3 seats Team; 5 Scale; paid additional seats
Status-page count	One public page on Pro; extra pages paid	Three Solo; 100 Team; unlimited Scale

UptimeRobot offers more free monitors, more included status pages, and 15-second polling on Scale. OnlineOrNot doesn't provide application tracing or log aggregation.

If that setup covers what you need, try OnlineOrNot alongside UptimeRobot for 14 days. You can also read the Terraform guide first.

2. Better Stack: for monitoring and on-call response

Better Stack combines monitoring with on-call schedules, escalation policies, incident timelines, and status pages. Its broader platform also provides logs and other telemetry.

Its on-call system assigns an incident to the current responder and escalates if nobody acknowledges it. That's useful if you currently maintain a separate rota and incident tool. If you already use PagerDuty and like it, you'll need less of what Better Stack sells.

Better Stack pricing

The free tier includes limited monitoring and a status page. Paid responder licenses are $34 per responder per month on monthly billing, or $29 with annual billing. Additional uptime monitors, heartbeats, and status-page options are separately priced. Playwright transaction monitoring costs $1 per 100 browser minutes.

Check which teammates need responder access. A free telemetry user and a paid incident responder have different permissions.

Because it bills browser minutes, a stuck script costs more than a quick run at the same frequency. Set timeouts and measure failed runs too. Two scripts taking 20 seconds each, every five minutes for 30 days, schedule 5,760 minutes before retries: $57.60 at its browser rate, on top of responder and monitor charges.

3. Checkly: for Playwright suites and CI workflows

Checkly supports API and browser checks, uptime monitors, and heartbeats. I'd look at it first if you want to run an existing Playwright project in production with its shared helpers and dependencies.

You can keep OnlineOrNot checks in Git with Terraform too. Checkly adds TypeScript/JavaScript constructs and its own CLI; it also has Terraform and Pulumi providers.

Browser Checks or Playwright Check Suites?

Its Playwright comparison distinguishes single-file Browser Checks from Playwright Check Suites:

Capability	Browser Check	Playwright Check Suite
Test source	One spec file	Multiple spec files
Browsers	Chromium/Chrome	Chromium, Firefox, WebKit
Packages	Fixed runtime dependencies	Custom public and private dependencies
Project structure	Partial configuration support	Playwright projects, tags, storage state, and configuration

If your spec contains import { login } from './helpers', you'll need to deploy the helper as well as the spec. Checkly's suites handle that project structure; its single-file Browser Checks use a fixed set of runtime dependencies.

You may still need to change the tests. A CI suite that seeds a database or resets accounts won't be suitable for repeated runs against production. Pick a path that you can run repeatedly without changing customer data. For internal services, Checkly offers private locations on Team and Enterprise.

Checkly pricing

Starter Detect costs $29/month on monthly billing, or $24/month with annual billing. It includes 50 uptime monitors, 3,000 browser runs, 25,000 API runs, and three users.

Starter Communicate adds status pages for $12/month, taking Detect plus Communicate to $41/month before extra usage. Resolve diagnostics cost extra too. Hobby has free allowances across the modules.

4. Uptime Kuma: for self-hosted monitoring

Uptime Kuma is an open-source monitoring tool you run yourself. It supports HTTP, keyword and JSON-query checks, TCP, ping, DNS, push monitors, Docker containers, and multiple status pages.

The software is free; you pay for hosting, backups, and any paid notification services. You'll also need someone to update and maintain it.

Where to run it

A Kuma instance inside your network can check a private database port or Docker container that an external probe can't reach. You'll still need an external check to test public DNS and the route through your CDN.

Don't put your only monitor on the same host as the app. If that host dies, the monitor dies with it. Running Kuma internally alongside a hosted external check gives you coverage for both private services and the customer-facing path.

Back up its configuration and test the notification integration after changing it. Kuma also supports push monitors for jobs; send the ping after successful completion, or a job that starts and then crashes could still look healthy.

5. Hyperping: for monitoring, status pages, and on-call

Hyperping combines uptime monitoring, Playwright browser checks, cron monitoring, status pages, server monitoring, and on-call features.

Paid plans include on-call schedules and escalation policies. Server agents collect CPU, memory, disk, and network metrics, so you can check the host as well as the public endpoint.

Hyperping pricing

The free plan includes 20 monitors with five-minute checks, one seat, and a basic status page. The rendered pricing page showed Essentials at €29/month or €290/year (about €24/month). That includes 50 monitors, three browser checks, three seats, and one custom-domain status page with 100 subscribers.

The pricing table lists 30-second uptime checks and five-minute browser intervals on Essentials. It charges by the number of browser checks rather than selling an included run allowance. Additional seats cost extra.

Browser credentials and failure output

Hyperping's browser-check documentation specifies headless Chromium, a two-minute run limit, per-monitor environment variables, and a default retry from another region before opening an outage. Its newer runtime documents failed-run traces and video, plus per-step reporting through test.step().

You can replay a failed run to see where it stopped. Its browser environment variables also let you supply credentials without putting them in the script; OnlineOrNot's documented browser workflow doesn't currently support that.

Essentials' three included browser checks can be cheaper than buying run packs if you want two scripts running every five minutes. Check the selected locations and retry policy when setting them up.

The status-page limits may push you onto another plan. Essentials includes 100 subscribers; Pro includes 1,000 and adds private and multilingual pages. You'll need Business to remove Hyperping branding. Extra Essentials seats cost €7/month each on the page checked.

6. Datadog Synthetic Monitoring: for teams already using Datadog

Datadog Synthetic Monitoring supports API and browser tests, managed and private test locations, and integrations with the wider Datadog platform.

If your team already uses Datadog APM or RUM, you can investigate a failed synthetic test alongside that data. Its browser recorder lets you create tests without writing a script and records screenshots for each step.

Datadog pricing

Synthetic API tests start at $5 per 10,000 runs, and browser tests start at $12 per 1,000 runs, billed annually. Month-to-month rates are $6 and $15 respectively; on-demand rates are $7.20 and $18.

At the month-to-month API rate, 20 endpoints checked once per minute for 30 days produce 864,000 runs: $518.40 before contract rounding or other charges. Two browser scripts every five minutes add 17,280 runs, or $259.20. Those figures don't include a status page, APM, logs, or incident-response seats.

Datadog's APM and RUM integration can help you trace a browser failure to a backend dependency, provided you've configured that telemetry. That's a reason to pay for it if you already work in Datadog. For simple endpoint monitoring, per-monitor pricing is often easier to budget than paying for every HTTP execution.

Pricing for two small-team setups

To compare bills, let's price 20 endpoints and a status page, then add two browser checks. Both examples use monthly billing.

UptimeRobot and Hyperping showed EUR prices; the others showed USD. Keep the currencies separate when comparing them. The figures exclude taxes, SMS/phone usage, white-labeling, private pages, retries, and manual runs.

Workload A: 20 endpoints and a shared status page

Assume 20 HTTP monitors, three dashboard users, and one public custom-domain page with email subscriber updates. For Better Stack, all three users need responder access. Polling intervals, retention, and incident features still differ between these plans.

Product	Required package and arithmetic	Monthly budget
OnlineOrNot	Pro $15 + one 25-monitor pack $10; unlimited users and public page included	$25
UptimeRobot	Team €41; 3 users and public page included	€41
Checkly	Starter Detect $29 + Starter Communicate $12; 3 users and public page included	$41
Hyperping	Essentials $29; 3 users and public page included	$29
Better Stack	3 Responder × $34 + one 50-monitor pack $25; 3 users and public page included	$127

Better Stack's bill includes its incident-response features. UptimeRobot includes 100 status pages when you only need one. With OnlineOrNot, you buy a smaller monitor allowance but can invite more developers without paying for seats.

At five dashboard users, OnlineOrNot still costs $25. Hyperping Essentials adds two €7 seats, bringing it to €43. UptimeRobot Team needs two extra login seats, or you could use Scale with five included seats. Checkly Starter only includes three users, so you'd need a different plan.

Workload B: add two browser journeys every five minutes

Keep Workload A and add two independent browser journeys, one scheduled execution per journey per cycle, in a 30-day month:

30 days × 24 hours × 60 minutes ÷ 5 minutes
  = 8,640 scheduled runs per journey

2 journeys × 8,640 = 17,280 scheduled runs

For OnlineOrNot and Checkly Starter, the included allowance is 3,000 browser runs. Covering the remainder requires 15 additional 1,000-run packs: ceil((17,280 - 3,000) / 1,000).

Product	Browser addition to Workload A	Combined monthly budget
OnlineOrNot	Pro $15 + one 25-monitor pack $10; unlimited users and public page included; 15 packs × $4 = $60	$85
Checkly	Starter Detect $29 + Starter Communicate $12; 3 users and public page included; 15 packs × $5 = $75	$116
Hyperping	Essentials $29; 3 users and public page included; 2 of Essentials's 3 included browser checks, at a 5-minute interval	$29
Better Stack	3 Responder × $34 + one 50-monitor pack $25; 3 users and public page included; If each execution averages 20 seconds: 5,760 minutes × $0.01	About $184.60 at the unit rate
UptimeRobot alone	Team €41; 3 users and public page included; no scripted browser-monitoring type in the reviewed catalog, so keep a separate browser tool.	Does not cover this workload alone

For Better Stack, actual duration, billing rounding, retries, and failed-run timeouts can change the browser total. For the other run-based products, budget additional executions separately. A 31-day month also schedules more runs.

For these two browser scripts, Hyperping's included checks are a good deal. I'd still compare the runtime against your scripts before buying: a cheaper plan doesn't help if it can't run your dependencies. Checkly's suite support may justify the extra cost; OnlineOrNot suits independent files and a team that wants unlimited dashboard access.

What if each region needs its own check?

Selecting three regions on one OnlineOrNot monitor still schedules 8,640 runs every five minutes in a 30-day month. It picks one region per cycle.

If you want each region checked every five minutes, create separate region-pinned checks. Two scripts in three regions then schedule 51,840 runs in 30 days. That's above OnlineOrNot's current 50,000-run self-service selector, so ask about capacity before setting it up.

The OnlineOrNot calculator can help you price the run allowance you'll need.

How to evaluate an UptimeRobot alternative

If you're still deciding, use these requirements to narrow the list:

Requirement	Products to compare
An app can be broken while its homepage is online	OnlineOrNot, Checkly, Better Stack, Hyperping, or Datadog browser monitoring
Developers need dashboard access without per-seat pricing	OnlineOrNot Pro
You need schedules, ownership, and escalations built in	Better Stack or Hyperping
Monitoring configuration should live in Git	OnlineOrNot's Terraform provider or Checkly's code-first tooling
Existing Playwright suites should become production monitoring	Checkly
Checks need to run inside your private network	Uptime Kuma, or a vendor's supported private-location offering
You already use Datadog to investigate production failures	Datadog Synthetic Monitoring
You only need a large free allowance of basic uptime checks	UptimeRobot may already be the right choice

Compare the bill for your workload

Write down your uptime monitor count, required interval, browser journeys, run frequency, regions, dashboard users, alert channels, and status pages. Add subscriber and private-page requirements too.

Include the details that affect the plan: standalone scripts or a full project, rotating probes or parallel execution, dashboard users or alert-only contacts.

If OnlineOrNot fits that workload, estimate your monthly cost before starting the trial.

Run both tools before switching

Start with one endpoint and leave its UptimeRobot check running:

1. Copy its full configuration: method, auth, headers, body, redirects, timeout, expected status, assertions, regions, and maintenance settings.
2. On a test service you control, return an error status, then 200 with an incorrect body. If you're adding browser checks, break an interaction while keeping the HTML response healthy. Record which checks fail.
3. Try a short outage and a sustained one, then make the service alternate between passing and failing during recovery. For regional coverage, make it fail only for the chosen probe region. Record when the tool detects the failure and when you receive the alert.
4. Open the alert as if you were on call. Can you find the failed assertion or browser screenshot? Does the incident reach your on-call tool, then resolve when the test service recovers?
5. Before moving the rest, check dashboard permissions, subscriber delivery, and Terraform drift. Keep the old configuration until the new one works for the people answering alerts.

Keep a small evaluation log:

Record	Why it matters
Failure introduced; first failed run; alert received	Separates scheduling, detection, and delivery
Selected regions; confirmation and recovery settings	Makes the comparison reproducible
Failed assertion and available artifact	Shows whether the alert helps diagnosis
Recovery received; incident/page resolved	Verifies the full lifecycle, not only opening

One alert arriving first isn't much evidence. Repeat the failures with the same settings before deciding that one tool is faster.

Ask about importing history and subscribers; don't assume they'll transfer. Keep any records you need before cancelling the old service.

For job monitoring, update the completion ping too. If the job keeps calling the old URL, the new monitor will report a missed run even though the job succeeded. Send both pings during the overlap, then remove the old one once you've checked delivery. Rotate endpoint credentials if the migration changes who can see them.

If you only want a different status page, you may not need to replace monitoring at all. OnlineOrNot can create status-page incidents from UptimeRobot webhook alerts; UptimeRobot's webhook integration requires an eligible paid plan.

If you want help moving your URLs, email me the monitor list. You can also start a 14-day OnlineOrNot trial without a credit card and leave UptimeRobot running while you compare them.

Frequently asked questions

What is the best UptimeRobot competitor?

For standalone browser checks alongside endpoint and job monitoring, I'd compare OnlineOrNot and Hyperping. Checkly is the stronger candidate for an existing Playwright project with dependencies. Better Stack includes on-call and incident response; Uptime Kuma lets you self-host. If your team already investigates incidents in Datadog, start there.

Is OnlineOrNot faster than UptimeRobot?

OnlineOrNot Pro and UptimeRobot Team both schedule uptime checks every 30 seconds. UptimeRobot Solo checks every 60 seconds and Scale every 15 seconds. The alert timing also depends on retries and confirmation settings, so compare those before drawing conclusions from the intervals.

Can I manage OnlineOrNot checks in Git?

Yes, with the Terraform provider. Keep the resource definitions and standalone Playwright files in your repository; file() reads the script when you run Terraform. You'll need a different deployment method for a complete Playwright project with dependencies.

Will selecting more regions multiply my browser bill?

OnlineOrNot selects one region per scheduled run, so adding regions to that monitor doesn't multiply scheduled executions. Creating separate region-pinned checks does. With another vendor, check whether its schedule rotates regions or runs them in parallel.

Does UptimeRobot support browser monitoring?

UptimeRobot doesn't list a scripted browser monitor in the product pages checked for this article. Its HTTP keyword checks can inspect response text, but they won't execute the JavaScript in your app or click through a flow. You'll need a browser check for that.

Is there a free UptimeRobot alternative?

OnlineOrNot, Better Stack, Checkly, and Hyperping have free tiers. Uptime Kuma is free software, though you'll pay for hosting it. Check the allowances before switching: UptimeRobot's 50 free monitors may cover more of your sites if five-minute polling is enough.

Can I switch without interrupting monitoring?

Leave the existing monitors running while you configure the new ones. Test failures, recovery messages, and alert destinations before turning off the old checks. Importing history is a separate question to ask the new provider.
