Synthetic monitoring for your vital click flows

Broken signup forms and flaky shopping carts are extremely frustrating to your customers. With Checkly's Browser checks you can accurately simulate interaction with your site and validate the correctness and performance of all your crucial click paths.

Real browsers

Your checks are run in actual Chrome browsers to achieve a 100% match with real world conditions. We run each session in a sealed off sandbox for extra security.

Validate all the things

In a Browser check you can check for specific content items, browser responses, visibility and error responses.


Take a screenshot at any stage in your transaction for quick and easy reference. You can take full page shots, or just a specific page element for more focus.

Monitor globally

We monitor your transactions from data center locations around the world.

CI/CD integration

Integrate your Browser checks into your QA or continuous delivery process by triggering adhoc runs from GitHub or the command line.

Coding optional

Use our browser plugin to record a script and import it into Checkly. Want more control? Dive into the code and tweak your script to perfection.
