Meticulous

Meticulous AI is an autonomous end-to-end testing solution that automates browser testing entirely. It records user interaction sessions across development and staging environments, then uses them to generate and maintain a comprehensive visual test suite covering every edge case—without needing developers to write or update tests. Every time a pull request is opened, Meticulous selects relevant recorded sessions, replays them against the updated version, and captures screenshots at key points. Any visual deviations appear as diff comments in the PR, enabling developers to quickly review and approve expected changes or catch regressions—no manual maintenance required. Built from the ground up on Chromium with a deterministic scheduler, the platform eliminates flaky tests and achieves lightning-fast execution at scale—replaying thousands of screens in under two minutes.
