disktree

See what fills your disk. A GPU-rendered treemap of any folder, built with GPUIX. A light, frosted port of tobi/disktree.

npx disktree            # scan the current directory
npx disktree ~/src      # or any folder
npx disktree /          # the whole disk

Runs on Node 20+ or Bun (bunx disktree). No Electron, no web view: GPUI paints it with Metal.

What it shows

• Tiles sized by disk usage (st_blocks × 512), coloured by kind: code, agent scratch, toolchains, synced, git, media, documents, cache
• Hatched tiles are reclaimable: caches, build output, node_modules beside a package.json, trash
• Worth a look ranks the largest things that could go
• Disk shows free space on the volume

How it scans

A pool of up to four worker threads walks the tree with synchronous lstat, one volume only, hardlinks counted once. Each directory keeps its 12 largest files as tiles and folds the rest into one "N smaller files" tile, which keeps a full-disk scan in memory.

/System/Volumes/Data is skipped when scanning /, since it mirrors /Users and /Applications.
