Zerocheck reads your PR diff, understands which user flows are affected, and generates the right tests automatically. No manual test authoring, no selector maintenance, no coverage gaps that grow with every sprint.
“We completely lost trust in our build, and red builds no longer meant anything. Before releases, we would spend about 3 days looking at all the failures and fixing them.”

“At Google, we found that 84% of pass-to-fail transitions are caused by flaky tests, not real bugs.”

“The same pattern kept repeating itself: a harmless-looking UI change, a merge, and then a failing test in CI.”

55% of teams spend 20+ hours per week maintaining E2E tests
60-70% of testing budgets go to maintenance, not new coverage
Zero competitors auto-generate tests from PR changes
With Playwright and Cypress, every new feature needs hand-written tests. Every UI change needs manual selector updates. The maintenance burden grows with every sprint until teams stop writing tests entirely.
AI testing tools (Momentic, testRigor, Mabl) still require you to author tests up front. They help maintain them, but nobody generates tests from the code changes themselves.
QA Wolf eliminates maintenance by outsourcing it to their team at $96K/year. Most growth-stage companies cannot afford that.
Developer ships a checkout redesign. QA lead spends 2 days updating 15 broken E2E tests: new selectors, new assertions, new test data. Next sprint, another redesign breaks 8 more. The maintenance backlog grows. Coverage shrinks. Bugs escape to production.
Developer ships the same redesign. Zerocheck reads the PR diff, generates tests for the affected checkout and cart flows automatically. No manual authoring, no selector updates, no maintenance backlog. Coverage grows with every PR instead of shrinking.

Zerocheck maps your codebase to user flows automatically
On each PR, tests are generated from your code changes
Results posted as PR comments with evidence artifacts
Zerocheck reads the diff, maps changed files to affected user flows, and generates tests for the impacted flows. If your PR changes checkout code, it generates checkout tests. Settings page code untouched? Those tests do not run.
For most flows, yes. Zerocheck generates tests from your code changes automatically. For edge cases or highly specific assertions, you can write tests in plain English. But the 20+ hours per week teams spend on test maintenance drops to near zero.
Every test is visible and reviewable in the PR comment with screenshots and step traces. If a generated test does not match your intent, you can adjust it in plain English. Tests fail closed on low confidence instead of silently passing.
Tests that generate themselves from your code changes. No authoring, no selectors, no maintenance.
