Replay

Replay QA is an autonomous testing tool for web apps from Replay. It explores your app, runs its own tests, and reports bugs with the evidence needed to fix them.

Replay QA opens your app in a real browser and works out the user journeys, including ones nobody wrote down. It runs tests against those journeys and records each run as a full recording. When it finds a failure, it returns the root cause, a suggested fix and the recording, so your team can act without reproducing the bug by hand.

• Explores app journeys without a written test suite
• Writes and runs its own tests in an instrumented Chromium browser
• Records every run for replay
• Returns bug reports with root cause and suggested fix
• Can be started with a prompt for a coding agent

Product and engineering teams that ship often and do not have a large QA group. Teams that need evidence for race conditions and timing bugs, which are hard to reproduce by hand, may find it useful.

You can try it on your own app with no credit card, and no existing test suite is needed. Pricing details are on the Pricing page of the site. The tool runs against your app in the browser, so the app must be reachable for testing.
