Free + open source for macOS
Reclaim the space your dev tools quietly keep.
Every toolchain leaves something behind: build caches, indexes, runtimes, model weights. Reclaim finds them, explains what each one is, and removes only what you choose. Nothing ever leaves your Mac.

Coverage
A curated catalogue, not a disk crawler.
Reclaim knows where each tool keeps its scratch data and measures those locations directly, instead of guessing from file sizes across your whole drive. The catalogue grows with every release, and anyone can add to it.
- Build systems
Derived data, intermediate objects and build outputs that every compile rewrites anyway, usually the largest single thing on a developer machine.
- IDEs and editors
Project indexes, language server data, preview and snapshot caches, and the logs that editors keep long after you have stopped reading them.
- Package managers
Download caches and registries across ecosystems, including versions of packages nothing on your machine still depends on.
- Runtimes and SDKs
Downloaded toolchains, device support files, system images, simulators and emulators, including the ones tied to versions you no longer target.
- AI tools and models
Local model weights, session transcripts and agent caches, which grow quietly and are easy to lose track of.
- Containers and VMs
Virtual disks that only ever grow. Reclaim measures them and hands you the tool’s own prune command rather than reaching inside.
Safety
Every item is rated before you touch it.
Nothing is removed without confirmation, and everything goes to the Trash by default. Only Safe items are preselected unless you explicitly opt Caution in.
Guarantees
What Reclaim will not do.
- Touch credentials or settings
Auth tokens, configuration and plugins are structurally excluded from the catalogue. A unit test enforces it on every build.
- Reach inside another tool’s store
Where a tool owns its own storage, Reclaim measures it and hands you that tool’s own cleanup command instead of deleting files underneath it.
- Guess
Every location in the catalogue is one someone identified, described and rated by hand. Nothing is removed on a pattern match.
- Phone home
No accounts, no analytics, no crash reporting, no payment. Beyond an optional update check, nothing leaves your Mac — and you can read the code to confirm it.
Find out what you are storing.
Free forever, open source, and built by a developer who got tired of running out of disk.
