Browser checks for your critical pages
Your server might be responding, but can your customers actually load your page? OnlineOrNot's Browser Checks verify that your most business-critical pages still work.
Cool screenshot, but what does this actually do?
Let me provide a bit of context: OnlineOrNot builds website monitoring tools - the first of which was a simple* uptime checker.
After running a few million checks, my customers started asking why I didn't support Single Page Applications (SPAs) like React - and the answer was pretty simple: the basic uptime checker just fetched the page, it didn't render anything.
OnlineOrNot's Browser Checks feature is how we solve that problem - by plugging Google's Puppeteer and real Chrome browsers into OnlineOrNot's existing uptime monitoring service, you can now reliably check whether your React (or Vue, or Angular, or whatever comes next) apps successfully render, and display the text you expect.
Tired of unreliable, slow, extremely "enterprise software"-feeling monitoring apps, I built OnlineOrNot to get false-positive-free alerts whenever anything goes wrong with my client's websites.
So you run Puppeteer in the cloud... can you run my Puppeteer scripts for me?
My aim for this Browser Checks feature is to allow Puppeteer test scripts to be added, and have the service send you screenshots of your app when things go wrong.
To start with however, Browser Checks currently supports:
- Loading your web app
- Searching for text on the page
- Retrying, and waiting for several failed checks before alerting
- Sending alerts to Email, Slack, SMS, and Webhooks when things go wrong
*Turns out running millions of uptime checks per week isn't as simple as you'd think!
Browser Checks are run in real Chrome browsers, isolated from each other for extra security.
Each failed check gets retried, and re-checked in separate regions before sending you an alert.
Alerts where you need them
Get notified when your check starts failing and when it works again via SMS, Email, Slack, and Webhooks.
Search your page for text to catch blank pages that don't display obvious errors (such as React, Vue and Angular apps)
