With Checkly and Playwright you can:
CREATE ACTIONABLE BROWSER CHECKS WITH PLAYWRIGHT TEST
Every browser check can collect error traces, screenshots and performance metrics. Use web-first assertions and auto-waiting to write highly reactive code that’s easy to read. Use Playwright traces to easily identify failed assertions and missing resources when you receive an alert.
ADOPT MODERN TESTING PRACTICES IN YOUR MONITORING
Reuse your existing Playwright code and use it for testing and monitoring. Leverage Playwright’s web-first assertions and auto-waiting to define your monitoring with confidence instead of flakiness.
DEBUG WITH EASE
Review failed monitoring alerts with automatically captured videos and screenshots to dive deeper.
Actionable browser checks with Performance and Error Tracing
Every browser check you run will automatically collect error traces, screenshots and performance metrics. Error Tracing enables you to easily identify JavaScript errors and missing resources while automatically generated screenshots help with debugging. Additionally, we have added performance metrics such as Google's Core Web Vitals to ensure your WebApp is snappy and provides a great user experience.
