Agentic QA that tests every change like a real user and opens the fix PR
Pie maps your real user flows from a URL or build and finds elements by looking at the screen, so there are no selectors to maintain.
Each PR is read and exercised against the running app, so regressions are caught before they reach users.
Tests survive redesigns and deep links because they rely on how the interface looks and behaves, not on brittle CSS or accessibility paths.
When Pie confirms a bug, it drafts a fix PR with the root cause and the applied change, ready for review and merge.

AI code review that runs your app on every pull request
TestDriver reviews every pull request automatically, reads the diff with its vision agent, and generates end-to-end tests straight from the PR content to prove the new behavior works.
Tests run your actual application in a real desktop sandbox—clicking, typing and reading the screen—so they catch runtime and visual bugs, not just code diffs.
When the UI shifts and a cached element no longer matches, the AI finds it again, updates the cache and continues, so tests survive redesigns without rewrites.
Once a test passes, TestDriver opens a fresh pull request with the generated Vitest test code committed, so coverage lands in your repo alongside the change it protects.
