Visualize dependency tree in package-lock.json and make it searchable.

Try our hosted version at

This app is built with React + Redux + glamor and is run purely in a browser. We will not send your package-lock.json thru the network.


We maintain many open source projects. But from time to time, our projects may eventually depended on outdated dependencies, some may also contains security vulnerabilities.

We built lock-walker in search for an easier way to look at a few things:

  • Find out what packages need to be updated to pass security check
  • De-dupe packages with multiple versions by upgrading some of its dependents
  • Find out what caused version conflicts
  • Make package-lock.json way more useful
