Replay QA comparison
Replay QA vs Tester Army
Tester Army runs plain-English tests on web and mobile and alerts you when a step fails. Replay QA explores your web app from a URL, records every session deterministically, and tells you why it broke and how to fix it.
The short version
- Tester Army tests are prompts turned into editable steps. Discovery runs explore toward a goal, capped at 12 steps and 15 minutes. Replay QA maps the app and discovers journeys itself.
- Tester Army gives you video, screenshots, logs and an agent transcript. Replay QA adds root cause analysis and a suggested fix.
- Tester Army covers iOS and Android. Replay QA is web only.

Where Replay QA goes further
Why it broke, not just that it broke
Tester Army tells you which step failed and what the agent saw. Replay QA agents time-travel through a deterministic recording to find root cause and attach a suggested fix.
No tests to write
Tester Army tests start from a prompt you write. Replay QA explores from a URL and writes and runs its own Playwright tests.
Security in the same tool
Replay QA’s optional Security Scan looks for injection, broken access control, weak authentication and business-logic gaps like cross-tenant data exposure.
Where Tester Army is stronger
