# Meticulous

> Meticulous automatically generates and maintains frontend browser tests from recorded user sessions to catch visual regressions.

The Meticulous app and documentation are hosted at app.meticulous.ai.

## When to use Meticulous

Use Meticulous when changing a web application's UI and checking for unintended visual changes, reviewing screenshot diffs on a pull request, or investigating a failed replay of a recorded user flow. A connected project and recorded sessions are needed to run replay tests.

For coding agents, start with the setup instructions below, then use the official CLI or MCP server to retrieve test runs, screenshot diffs, and replay details. Authenticate with the user's Meticulous account before accessing project data.
