Replay QA

Replay QA is an autonomous testing platform built for the era when AI agents write code and ship apps in hours, not weeks. Drop in a URL or connect a GitHub repo, and Replay QA explores your app, writes its own Playwright tests, records every session, finds real bugs, and hands your coding agent the root cause and suggested fix — no test suite to write, no QA team to manage.

Built by the team behind Replay's time-travel debugging engine (used by Vercel, Glide, and Pantheon), the platform discovers user journeys automatically, runs tests with full session recording, and produces detailed bug reports with runtime breakdowns — function calls, DOM mutations, network requests, and state changes. Every bug comes with a confidence-scored root cause analysis.

Two modes: continuous quality gate via GitHub integration (runs on every PR or main branch update), or on-demand testing by pasting a URL. Free plan includes 25 credits per month. Paid plans start at $20/month for individuals and $200/month for teams.
