What is Checkly

Checkly is a monitoring platform that checks if your websites and apps are working properly. It runs automated tests from different locations around the world to make sure everything functions as expected. Unlike traditional monitoring tools, Checkly lets you write your monitors as code using JavaScript or TypeScript.

The platform specializes in three types of monitoring: browser checks that simulate real user actions, API checks that test your endpoints, and heartbeat monitoring for scheduled jobs. You can use the same Playwright tests you write for development as production monitors.

Checkly provides instant alerts when something breaks, showing you exactly what went wrong with screenshots, logs, and traces. It includes built-in status pages to communicate issues to your users and team members automatically.

Features of Checkly

  • Playwright-based browser checks for user journey testing

FAQ's About Checkly

Yes, Checkly offers a free Hobby plan with 10 monitors, 1,000 browser checks, and 10,000 API checks per month. This is perfect for personal projects and learning. Paid plans start at $29/month for teams needing more capacity.
Checkly is built for developers and uses code-based workflows. Instead of clicking through interfaces, you write monitors in JavaScript/TypeScript and manage them like your application code. You can reuse existing Playwright tests as monitors and deploy everything through CI/CD pipelines.
Yes, Checkly supports Private Locations starting from the Team plan. You can install the Checkly Agent in your own infrastructure to monitor internal services, databases, and applications behind firewalls while still managing everything from the Checkly platform.
When a check fails, Checkly immediately sends alerts to your configured channels (Slack, email, SMS, PagerDuty, etc.). You get detailed debugging information including screenshots, console logs, network activity, and traces. Your status page is automatically updated if you have one configured.
Absolutely! Checkly natively supports Playwright, so you can take your existing test scripts and run them as production monitors. This means you write tests once and use them both for development testing and production monitoring, avoiding duplicate work.
