About
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.
Problem
E2E test failures are time-consuming to debug because error messages only show what failed, not why, forcing developers to spend hours reproducing issues manually.
For
software development teams using end-to-end testing with Playwright or Cypress
How it works
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.
