diskdiet

See where your developer disk space went, and get it back safely. One tool for macOS, Linux and Windows: a CLI, a desktop app, a VS Code extension and an MCP server for AI assistants.

diskdiet scanning and cleaning (made-up demo data)

Disk full right now? Nothing to install

npx diskdiet            # see what's using space (changes nothing)
npx diskdiet clean      # free what's older than 30 days, after showing the list
Fixes for the exact problem you have: no space left on device · huge npm cache · old node_modules · Docker · pip & uv · Xcode

Why diskdiet

Package managers never forget. After a year of installs, the npm cache alone can pass 40 GB, and Docker images, the pnpm store, Gradle caches and old projects' node_modules add more. Most cleaners either wipe everything, so your next installs crawl, or handle one tool.

diskdiet shows the whole picture first, then removes only what you haven't used lately: by default, anything unchanged for 30 days.

  • One breakdown

    npm, Yarn, pnpm, Bun, pip, uv, Cargo, Go, Gradle, Maven, Playwright, Cypress, Xcode, Docker, and the node_modules and target folders of projects you haven't touched. Biggest first.

  • Old, not everything

    Removes what hasn't been used for 30 days (or 7, or 90), so the packages you use every day stay cached and installs stay fast.

  • Safe by default

    Shows exactly what it will remove and asks. Never outside a cache folder, never follows symlinks, uses pnpm store prune and docker prune where they exist, keeps Docker volumes, and waits while a package manager is installing.

  • Wherever you work

    CLI · desktop app with a tray icon · VS Code · AI assistants (MCP)

The desktop app

The diskdiet app (made-up demo data)

Pick an age, untick anything you want to keep, and free it in one click. The app stays in your menu bar or system tray, checks every few hours, and tells you when more than 10 GB could be freed. More about the app.
