Helping Companies Ship 10X Faster
Your suite breaks more than your code.
Your E2E suite fails for reasons unrelated to your feature. Selectors change, flows shift, timing breaks. You spend hours debugging failures that have nothing to do with the code you shipped. Meanwhile, PRs pile up and your actual work waits. Test maintenance has become a second job, and it is one nobody signed up for.
The frustrating part is that the suite exists for good reason. You need that safety net. But when it cries wolf often enough, engineers stop paying attention. Failures get dismissed. Real regressions slip through because the signal is buried in noise. You end up in a worse position than if the suite did not exist at all: slower to ship, no more confident, and now responsible for keeping a flaky test infrastructure alive on top of everything else.
What changes with Checksum
Outcome-focused quality that works in the background, so you don't have to.
Self healing
Tests that fix themselves. When the UI evolves, Checksum automatically heals broken tests and opens a PR for your review. No more selector archaeology.
Tested before review
Feedback before review CI Agent runs 50-200 targeted tests on every PR. By the time someone reviews your code, it's already been executed and verified.
Reliable signal
A suite you can trust again 82% lower failure rates vs. manual maintenance. Fewer false alarms. Clearer signal when something actually breaks.
Trusted by fast shipping teams
Frequently Asked Questions
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.
