Your coding agents open more pull requests than anyone can test by hand. A pull request can pass every test and still break sign-up or checkout. Paidwen blocks that pull request before it reaches production. You choose your critical features once. On every pull request, Paidwen uses your app like a real user and blocks the merge when one of them breaks, with a video of what broke. You write no test code, and your code never leaves your own GitHub Actions runner.
