# Replay

> Replay is an AI-native QA platform. Replay QA autonomously explores your web app, records every session with time-travel debugging, finds real bugs, and gives your coding agent the root cause and fix.

## Pages

- [Replay QA — AI wrote the app. Replay QA finds what broke.](https://www.replay.io/agent/index.md): Add your GitHub repo for continuous testing, or drop in a URL for a one-time check. Replay QA explores your app, finds real bugs, and gives your coding agent the root cause and fix.
- [How Replay QA Works](https://www.replay.io/agent/how-it-works.md): From URL to bug report — automatically. See how Replay QA explores your app, records every session, and delivers root cause and fix for every bug it finds.
