Replay
E2E test failures analyzed automatically — root cause and fix posted to your PR

Replay is a CI agent that automatically records every end-to-end test run and uses time-travel debugging to analyze failures. When a test fails, the agent traces the exact sequence of events and posts a root cause analysis, failure trace, and suggested fix as a GitHub PR comment. It integrates with Playwright and Cypress without requiring changes to existing test code.
Replay records every test run deterministically capturing all function calls, DOM mutations, and network requests, then an AI agent analyzes the recording on failure and posts root cause and fix suggestions directly to the GitHub PR.
