Works alongside Replay QA
Replay QA vs QA Wolf
QA Wolf builds, runs and maintains your end-to-end test suite, with its own agents and experts. Replay QA explores your app autonomously and explains why things break, down to a suggested code fix.
The short version
- QA Wolf is built around a durable regression suite, either self-serve or fully managed. Replay QA needs no suite.
- QA Wolf separates app bugs from out-of-date tests and repairs the tests. Replay QA diagnoses the app bug and suggests a code fix.
- QA Wolf covers web, iOS, Android and Electron. Replay QA is web only.
At a glance
| Dimension | Replay QA | QA Wolf |
|---|---|---|
| What you provide | A URL or a GitHub repo. No setup beyond that. | Self-serve platform, or a managed service via sales. |
| Test suite | None needed. Writes and runs its own Playwright tests. | Playwright and Appium suite, created and maintained for you. |
| How bugs are found | Agents explore the app and discover user journeys themselves. | Mapping AI maps test cases; the suite runs on schedule or deploy. |
| Evidence | Deterministic time-travel recording of every session, plus video and annotated screenshots. | Video, Playwright traces, console logs; human-verified reports. |
| Root cause analysis | Agents time-travel through the recording; each report has a confidence score. | Classifies failures as app bug or outdated test. |
| Suggested code fix | Every bug report includes a suggested fix for a coding agent. | Repairs tests, not application code. |
| Needs real user traffic | No. Tests before you ship. | No. |
| Native mobile | No. Web apps, tested in Chromium. | Yes, including real iPhones and iPads. |
| Coding agent access | Replay MCP server, REST API, and PR comments. | MCP server for Claude Code, Codex and others. |
| Pricing | Free (25 credits/mo), Starter $20/mo, Pro $200/mo. | 1¢/AI credit + 15¢/runner minute; managed tier by quote. |

How they work together
Suite plus diagnosis
QA Wolf keeps a regression suite running across web and mobile. Replay QA explores beyond the suite and, when something breaks, records the run and finds root cause in your app code.
Both speak Playwright
QA Wolf tests are open-source Playwright. Replay QA writes and runs its own Playwright tests too, so neither locks you into a proprietary format.
Where Replay QA goes further
Start in minutes, from a URL
Paste a URL or connect a GitHub repo and Replay QA maps the app and discovers journeys itself.
Fixes for the app, not the test
Replay QA agents time-travel through a deterministic recording to find root cause, and every report includes a suggested fix for your coding agent.
Security, accessibility and performance
The same run checks WCAG issues and performance problems, with an optional AI pentest.
Where QA Wolf is stronger
Managed coverage
QA Wolf’s Coverage as a Service has its team create, run, investigate and maintain tests, with human-verified bug reports.
Mobile and real devices
QA Wolf covers iOS, Android and Electron, including real devices.
