api monitoring

No more broken APIs

Make sure your API always responds quickly and with the correct payload. Get started with our Swagger or cURL importer and super easy API monitor creator.

Monitor your API performance from 16 different locations, as often as once every minute. We'll also check if your SSL certificate is about to expire.

synthetic monitoring

No more broken web apps

Monitor and validate your most crucial site transactions like logins, shopping carts and onboarding flows. Take screenshots to get instant insights into what's working and what's not.

Scripting browser click flows used to suck. Not anymore. Checkly uses Google's Puppeteer framework to run your flows in a Chrome browser.

Stats & metrics

Insights without limits

Doing a root cause without complete and accurate data is insane. But too much detail can also be distracting. That's why next to calculating aggregates to keep an overview, Checkly stores each and every raw result for you and your team to dive into.
