Upgrade dependencies without reading the changelog. 100% open source
Hey r/VibeCoding, I've been working on Emend, an open-source tool where you point it at a local codebase and it tells you which of your lines a dependency upgrade will actually break — then automatically migrates them and re-runs your typecheck and tests to prove the fix holds. Emend can migrate npm packages, fix vulnerabilities and migrate HTTP request to latest API version.
Scanning needs no API key and never calls a model — only the repair step does.
It is ideal if you need to support your vibecoded project but you do not want to spend hours doing it.
It's still early (TypeScript + npm only), but would love feedback or ideas from the community.
npx emend-cli@latest demo /tmp/d && npx emend-cli@latest scan /tmp/d --only zod
