Coding agents write tests when you ask them to. Checksum runs continuously in the background, generating, executing, and healing tests automatically without anyone prompting it. The difference is on-demand versus always-on. Most teams find they're spending more time fixing AI-generated tests than writing them. Checksum removes that loop entirely.

No. It removes the low-leverage work, writing and maintaining tests that break every time the UI changes. QA teams that use Checksum spend less time on upkeep and more time on exploratory testing, edge cases, and quality strategy.

Most teams are running their first tests within a day. Checksum connects to your existing CI pipeline and works with your current frameworks. There's no rip-and-replace.

Yes. Tests are delivered as real code: Playwright for end-to-end tests that lives in your repository. You can run them anywhere, modify them however you want, and take them with you. No vendor lock-in.

When a selector changes or a flow shifts, Checksum detects the failure, fixes the test, and opens a PR for your review. You see exactly what changed and can approve or reject it. About 70% of failures resolve this way without any human involvement.

Checksum works alongside what you already have, not instead of it. It fills gaps in coverage, keeps existing tests green, and generates new tests as your product changes.

Most teams start by reviewing everything, then gradually extend trust as they see the results. You always have controls: tests come as PRs, healing changes are reviewable, and you can adjust scope at any time.
