leanest: Jev-Powered End-to-End Test Optimization

Sep 20

leanest is a tool that leverages Jev to execute only the end-to-end tests relevant to a given pull request, significantly reducing test execution time.

Introducing leanest: uses Jev by @typesafeai to run only the e2e tests your PR can actually affect. Diffs your PR, judges each test in parallel, runs the rest through your own Playwright/Vitest. Fails open, BYOK. 153 tests -> 7. 7m25s -> 1m28s. leanest.pages.dev
