Checkly is a developer-first monitoring platform for APIs and web applications that runs synthetic checks — headless browser scripts (Playwright) and API monitors — on a schedule from global locations to ensure your app works correctly at all times. Unlike uptime ping tools (UptimeRobot), Checkly runs real browser automation to test critical user flows: checkout, login, signup. Monitoring-as-code: checks are defined in code, stored in Git, and deployed with CI/CD.

The verdict
Our take on Checkly
Best developer monitoring for E2E testing in production. Checkly's monitoring-as-code approach means the same Playwright tests developers write for CI run continuously in production globally — closing the gap between testing and monitoring.
