Meticulous
Meticulous records real web-app sessions, generates end-to-end tests, and compares pull-request changes for visual and behavioral regressions.

Meticulous records interactions with web applications in local, staging, preview, or production environments. It maps sessions to code coverage, builds and updates a test suite, then replays selected sessions against old and new app versions to surface differences.
Engineering teams use it with CI and pull requests, alongside or instead of manually written frontend tests. It requires recorded user flows and setup in the application and CI pipeline; official tier pricing was not readable on the pages checked.
