Zero-flake test runs in CI
A reliable release signal you can trust on every build.
Run your Playwright tests in parallel across browsers and environments. Get a clear pass/fail signal you can trust — no more re-running to see if it passes this time.
Flaky tests destroy confidence in your test suite. Stably gives you a reliable release signal so you can ship with confidence.
- Parallel test runs across browser and environment combinations
- Failures grouped by root cause, not scattered across logs
- A clear release-ready signal for every build
