Which upgrades will break your repo?

Paste a public GitHub repo. We upgrade each outdated major (TypeScript 7, ESLint 10, vitest 5, React Router 7…) in a sandbox and run your own type-check, build, lint and tests. You get a shareable report in about ten minutes.

Nothing is pushed and nothing is installed on your repo. The code runs in a throwaway container with no network during checks.
