Replay provides AI coding agents with full browser runtime context to automatically identify root causes and generate specific fixes for bugs.

Replay captures every DOM change, network request, and state update during a browser session, creating a deterministic recording. This recording is then analyzed to pinpoint the exact root cause of a bug and deliver a detailed, implementation-ready fix directly to coding agents or via a Chrome extension, eliminating manual debugging.
