Know what breaks before you upgrade.
Not a security scanner. Not a dependency updater. Linchpin tells you exactly what will break, what's safe, and the order to upgrade without blowing up your app.
Check your Health Score
Drop your package.json here. We'll check every dependency against the npm registry.
Folder scanning requires Chrome, Edge, or Opera. Or upload each workspace's package.json separately.
Breaking Change Detection
See which updates will break your app before you run npm install. Not after.
Safe vs. Dangerous
Every package gets a verdict: Update now, update carefully, or skip entirely.
Upgrade Order That Works
We tell you what to upgrade first so peer dependencies don't explode.
One Command Per Step
Copy, paste, run, test. Move to the next step only when you're ready.
