Browser Checks for your
How it works
OnlineOrNot builds website monitoring tools - the first of which was a uptime checker.
After running a few million checks, my customers were asking why I didn't support Single Page Applications (SPAs) like React - and the answer was pretty simple: the basic uptime checker is better suited for static pages.
With OnlineOrNot's Browser Checks (powered by Puppeteer), 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.
Browser Checks 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/Discord, SMS, and Webhooks when things go wrong
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)
Bring the whole team
Monitoring is your whole team's job, not the responsibility of just one person. Bring your whole team at no extra cost.
