OnlineOrNot vs UptimeRobot
Already have Playwright tests? Put them to work.
- OnlineOrNot can run your standalone Playwright scripts on a schedule. 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.
- If you only need HTTP monitoring, UptimeRobot may already do everything you need. Its Team plan checks every 30 seconds; Scale checks every 15 seconds [1].

What you get with each tool
Both tools monitor uptime and cron jobs. Here are the differences.

| Monitor allowance | Free: 50; Solo: 10 or 50; Team: 100; Scale: 200 or 500 [1] | 3 Hobby; 35 Pro, plus 25-monitor packs |
| Multi-location monitoring | Available on paid plans across four regions [2] | Configurable regions |
| Cron job monitoring | Included on paid plans [3] | Yes |
| Browser monitoring | No Playwright script support listed [1] | Standalone Playwright scripts; not full project deployment |
| Custom domain status pages | Solo and above [1] | Paid plans |
| SSL certificate checks | Paid plans list advance expiry alerts at 30, 14 and 7 days [1] | Alerts on invalid or expired certificates when SSL verification is enabled. No advance-expiry reminders |
| Team members | Team: 3 login seats; Scale: 5; additional seats available [1] | 2 on Hobby; unlimited on Pro and Enterprise |
| Advanced notification routing | Integrations vary by plan [1] | Per-check integrations; on-call scheduling via external tools |

How to choose
Written by OnlineOrNot. This is a comparison of published capabilities, not a reliability benchmark. Unverified claims are not treated as missing features. Documented examples, not hands-on benchmark results.
Choose UptimeRobot when
You want the free HTTP-monitor allowance, faster paid intervals or advance certificate-expiry reminders described in its current plans.
A public endpoint can be healthy while a job has stopped
Your application responds normally, but its scheduled invoice job never completes.
Use UptimeRobot’s heartbeat monitoring to detect the missing completion signal; uptime polling alone will not prove the job ran. Keep it when those checks and team features meet your needs, and add a script runner if you also need login and checkout validation.
Example documentationLimitations and requirements to check
- Its faster paid intervals and advance certificate-expiry reminders are not replaced by OnlineOrNot Pro. Verify seats, currencies and plan limits.
Migration boundaries for UptimeRobot
- Recreate supported endpoints and notifications, and validate failure and recovery in parallel. Keep any product-specific features OnlineOrNot does not replace.
Choose OnlineOrNot when
You want focused managed uptime, API checks, standalone Playwright scripts, heartbeats and hosted status pages without adopting a full observability platform.
A success page is not a completed checkout
Your storefront still responds with HTTP 200, but submitting an order no longer reaches the confirmation screen.
Use a standalone Playwright journey to sign in, submit a test order and assert the confirmation. An HTTP availability check alone does not exercise those steps. Keep native on-call scheduling or APM in a separate product if you need them.
Example documentationCurrent limitations
- Hobby is free and includes 3 uptime monitors at 3-minute intervals, 1,000 browser runs per month, 2 team members and 100 email status-page subscribers. SMS, webhooks and on-call integrations are not included on Hobby.
- Pro HTTP checks support 30-second scheduling, not a guaranteed 30-second alert. Browser frequency, run duration and region count affect usage.
- Alerts on invalid or expired certificates when SSL verification is enabled. No advance-expiry reminders
- Standalone browser scripts do not replace a full Playwright project, arbitrary dependencies, private runners, application tracing or native on-call scheduling.
- Enterprise reliability guarantees depend on your contract. No zero-false-positive or faster-than-competitors guarantee is offered.
Comparable workload costs
20 uptime monitors, three active operators and one public status page. Usage-priced HTTP estimates assume one request per monitor every minute for 30 days in one location: 864,000 HTTP executions. The browser workload adds two journeys every five minutes for 30 days in one region: 17,280 executions. More regions, retries, longer runs or retained products can add cost. HTTP intervals vary by plan; these are not equal-performance claims.
Monthly prices where published, before tax; currencies are not converted. Annual commitments, usage estimates, incomplete packages and subtotals are labelled. Browser totals include the base workload unless explicitly marked incomplete. Check current quotes before purchasing.
| Product | Uptime workload | With browser journeys (total) |
|---|---|---|
| OnlineOrNot | USD $25/month Pro $15 + one 25-monitor pack $10; unlimited users and public page included | USD $85/month Pro $15 + one 25-monitor pack $10; unlimited users and public page included; 15 packs × $4 = $60 |
| UptimeRobot | EUR €41/month Team €41; 3 users and public page included | Does not cover this workload alone Team €41; 3 users and public page included; no scripted browser-monitoring type in the reviewed catalog, so keep a separate browser tool. |
OnlineOrNot: pricing assumptions
- Monthly USD, before tax. One public page and unlimited Pro members are included; additional pages, private-page features, runs and monitor packs cost extra.
UptimeRobot: pricing assumptions
- Monthly EUR, before tax. The configuration below includes three team members and one public status page; compare features, not just the entry headline.
Migration boundaries
- Recreate supported checks, credentials, regions, assertions and alert routing. Test a controlled failure and recovery in parallel before cancelling your current service.
- Historical incidents, response-time data, SLA reports, integrations, status-page domains and subscriber lists do not automatically transfer. Export an archive and plan each cutover.
- Keep unsupported capabilities in the existing product. Agree assisted-migration scope and timing; do not send secrets by email.

What would it cost?
Monthly prices are in EUR for UptimeRobot, as shown on its site when checked, and USD for OnlineOrNot. We haven't converted currencies; check UptimeRobot's price in your region before buying [1].
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.
| Feature | UptimeRobot | OnlineOrNot |
|---|---|---|
| 10 HTTP monitors, one operator | Solo: 10 monitors, 60-second checks, from €10/month [1] | 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. [4] |
| 50 HTTP monitors, 30-second checks, up to 3 dashboard users | Team: 100-monitor allowance and 3 login seats, from €41/month [1] | $35/month for up to 60 monitors. Unlimited team members [4] |
| 100 HTTP monitors, 30-second checks, up to 3 dashboard users | Team: 100 monitors and 3 login seats, from €41/month [1] | $55/month for up to 110 monitors. Unlimited team members [4] |
| 200 HTTP monitors, 15-second checks | Scale: 200 monitors and 5 login seats, from €77/month [1] | Pro checks every 30 seconds, so it does not meet this requirement. |
What about the free plans?
UptimeRobot gives you 50 monitors at five-minute intervals. OnlineOrNot gives you 3 monitors at three-minute intervals, plus 1,000 browser runs a month and 2 team members [1][4].
For lots of basic URL checks, UptimeRobot has the larger free plan. If you want to try a Playwright check, start with OnlineOrNot Hobby.
Reasons to stay with UptimeRobot
If you need a status page for each client, pay attention to the page count. UptimeRobot Team includes 100 status pages and Scale includes unlimited pages. OnlineOrNot Pro includes one public page; each extra page costs $24/month on monthly billing [1][4].
UptimeRobot also sends certificate-expiry reminders 30, 14 and 7 days before expiry. OnlineOrNot alerts when a certificate is invalid or expired, not before. If you rely on those reminders, you'll need to keep them elsewhere [1][5].
Try OnlineOrNot before you switch
Start with a few checks. Copy their URLs, request settings and expected responses, then connect your alert channel and subscribe each check to it.
Test an outage and recovery on an endpoint you control, not a production service. For cron jobs, update the heartbeat URL. Keep UptimeRobot running until the new checks and alerts work.
