Checkly

What is Checkly?

Checkly is a synthetic monitoring platform where checks are written as actual TypeScript/Playwright code that lives in your repository, not configured through a point-and-click UI. That means your monitoring setup gets version control, code review, and the same tooling as the rest of your codebase, instead of living in a separate dashboard nobody remembers to update.

Key features

• Checks are real Playwright scripts, so anything Playwright can do (multi-step flows, assertions, screenshots) is fair game for a monitor
• Checks-as-code workflow: define monitors in your repo, deploy them via CLI or CI
• API monitoring alongside browser checks, for testing endpoints directly without a full browser
• Global check locations for testing latency and uptime from multiple regions
• Alerting integrates with common on-call and chat tools

Who it's for

Fits teams already comfortable with Playwright who want monitoring that lives in code and gets reviewed like any other change. If you just need a basic "is it up" ping check, that level of setup is more than you need.
