Meticulous injects a JavaScript snippet into the client side application that captures user behaviour

The data in these sessions include user events (clicks, keydowns, etc.), network activity, and browser metadata

When replaying the session, Meticulous simulates all user events in the same sequence they were recorded and takes screenshots at important moments

Meticulous automatically selects the set of sessions that provide the highest level of coverage on a daily basis

While automatic session selection is usually sufficient, you do have the ability to manually select any sessions. This ensures that they are executed on every test run. We don't advise doing this as it's an additional burden and adds limited value

Meticulous automatically initiates a test run for every new commit to a branch with an open Pull Request

Meticulous comments directly on Pull Requests with a link to view and potentially review any visual differences

The default grouping is Similar Differences, which groups the underlying elements that changed regardless of the screen the change occurred on. This allows you to typically only need to sample a small subset of the total differences

The drilldown view enables you to view more session specific functionality such as viewing the HTML difference, a full timeline, and replays of the simulations

Debug with AI initiates an agent debugger with full context on your code change and the session replayed, and provides a diagnosis of why a change happened

You can get your agents to communicate directly with Meticulous using our agentic skills. See the documentation for more information. This allows them to directly run test runs and check results to validate changes
