A good fit for
Relevant to developers checking explicitly defined UI conditions and inspecting execution evidence in CI or agent workflows.
Before you choose
Local model downloads and hardware are required; external models and cloud grids have separate fees. Dashboard upload is opt-in and changes where recordings are stored. Agent-judged checks are separate from deterministic assertions, and imported Playwright tests may be incomplete. Replayed green runs do not guarantee an unchanged application remains correct. Saved login state is sensitive. Reliability, secret masking and performance were not independently tested. No package installed, site automated, credentials saved or test executed.
Workflow and handoff
Use a test account, define deterministic assertions for the important outcome, and inspect failures and imported-test gaps before relying on a verdict.
