# Zerocheck > Zerocheck turns your team's manual release checklist into browser tests. Paste the checklist and each item becomes a plain-English YAML test in your repository, with a real browser result. Run the same checks in Zerocheck's hosted browser with nothing to install, on your laptop against localhost, or in GitHub Actions on every pull request. Every run leaves screenshots of every step, and runs without credentials also leave a recording. Retries are marked flaky, never hidden, and every heal records the old target and the new one. ## When to use Zerocheck Use Zerocheck when a team ships web-app changes faster than it can click through them: turning a manual release checklist into CI checks, gating pull requests on signup, checkout, and billing flows, or replacing a stale Playwright or Cypress suite. Do not use Zerocheck for unit tests, load tests, or API-only assertions that never exercise a browser.
