A better way to monitor your APIs and site click flows
Monitor the performance and correctness of your API endpoints & vital site transactions from a single, simple dashboard.
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.
site transaction monitoring
No more broken shopping carts
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.
Alerting when and how you want it
Keep your team up to date with a generous helping of SMS messages and unlimited email, Pagerduty, Slack and web hook notifications. Control exactly how, when and how often you get alerted. Of course, "double-checking" is enabled by default to never get false positives.Learn more
