Stop maintaining tests. Start shipping features.
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.

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
No. Checksum runs inside your existing CI pipeline using the frameworks you already have, PyTest, Jest, Playwright, whatever your team uses. No rip-and-replace required.

No. The CI Agent runs targeted tests on what changed in each PR, not your full suite. It's designed to add signal without adding significant time.
Checksum automatically heals broken tests and opens a PR for your review. You approve the fix rather than hunting down the selector.
Yes. Tests are generated as real Playwright code that lives in your repository. No vendor lock-in.
Checksum connects to your CI and your codebase. Most teams are running tests on PRs within a day, without any manual test setup.
