Monitor every critical user journey — before customers feel it

Uptime monitoring checks whether a URL or TCP port responds — it answers "is it up?". Synthetic monitoring goes further: it simulates real user actions (clicking, filling forms, navigating) using a real browser to answer "does it actually work?". If your checkout page loads but the Pay button throws a JavaScript error, uptime says green — synthetic catches it.

No. If your team already uses Playwright for end-to-end testing, you can port those same test files directly into Checkly as Playwright Check Suites — custom dependencies, fixtures, StorageState, and all. Browser Checks and Multistep Checks use the same Playwright API, so existing test knowledge transfers immediately.

Browser Checks and Multistep Checks can run as frequently as every 1 minute from any global location. API Checks support intervals down to 10 seconds. You can also run checks on demand via the CLI or API for instant validation during deployments.

Checkly immediately captures a full screenshot, video replay, Playwright trace, console logs, and network requests from the failed run. Rocky AI analyzes the failure and provides a plain-language root cause summary. Alerts fire to Slack, PagerDuty, email, or any webhook — with all that context attached.

Yes. Checkly Private Locations let you deploy a lightweight monitoring agent inside your own infrastructure — VPCs, staging environments, or on-premises networks. It runs the same checks as our public cloud locations, with all data staying inside your network.
