Show HN: Browser-Based Uptime Checks (onlineornot.com)

Hey HN,

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 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. When things go wrong, you get notified via Email, SMS, Slack, or via Webhooks.


Looks really good. I like the idea that puppeteer instance checks the page. Keep going!
