Dependency tracking · free for 3 projects

## Know when your own dependencies move

This page watches array-flatten. inlinr reads your package.json and keeps the same watch on every dependency you declare, then tells you only what needs you.

- Advisories reach you  
An email when a critical or high advisory affects a project, before the next install.
- Upgrades checked first  
Peer ranges, Node, ESM-only and types changes read before you bump.
- Only what matters  
Majors and breaking notes stay; patches and sibling bumps fold into one line.
