Dependency tracking · free for 3 projects

## Know when your own dependencies move

immer shipped a new major in the last 12 months, among 35 releases. inlinr shows which of your projects are behind, and what the upgrade breaks.

- 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.
