Reclaim

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.

  • Safe

    Regenerated automatically. Build caches, indexes and logs. The first build afterwards is slower, and nothing else changes.

  • Caution

    Restorable, but it costs something. Large downloads have to be fetched again, and some history, like old crash symbols and past sessions, does not come back.

  • Destructive

    Removes things you created, like virtual devices and their saved state. Never preselected, and always flagged again at confirmation.

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.
