What I like best about Checkly is its "monitoring-as-code" approach, which fits perfectly into modern CI/CD workflows. The ability to write API and browser checks in JavaScript/TypeScript using Playwright, commit them to Git, and run them globally is a game-changer. It feels like an extension of your development process—not a separate tool you have to babysit.
The integration with Playwright is especially powerful—it allows for deep browser-based testing with rich artifacts like screenshots, traces, and console logs. Checkly also makes alerting simple and flexible with Slack, email, and webhook support, so you always know when something breaks. Review collected by and hosted on G2.com.
While Checkly is powerful, there are a few areas where it could improve. The pricing tiers can feel a bit rigid—especially for growing teams that fall between the limits of Starter and Team plans. More flexible or usage-based billing would be helpful.
Also, while the Playwright integration is great, the learning curve can be steep for teams new to writing tests in code. Some advanced features could use more in-depth documentation or examples.
Lastly, data residency options are limited. For teams with strict compliance needs (especially in the EU), having more control over where monitoring data is stored would be a big plus. Review collected by and hosted on G2.com.
