Automated e2e screenshot testing without writing or maintaining tests

What it does

Meticulous is a tool to automatically catch UI bugs in your web application with zero-effort. Install our JavaScript snippet onto production or staging and dev environments, which records user sessions by collecting clickstream and network data. When you post a pull request, Meticulous selects a subset of sessions which are relevant and simulates these against the frontend of your application. Meticulous takes screenshots at key points and detects any visual differences. It posts those diffs in a comment for you to inspect in a few seconds. This eliminates the setup and maintenance burden of UI testing.
