Active Reliability for Modern DevOps Teams
Monitor the performance and correctness of your API endpoints & vital site transactions from a single, simple dashboard.
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.
