Windsurf editor cache on Mac: safe to delete?

Safe to deleteRegenerated automatically; Thermo deletes it outright.

Quit first: Windsurf

Where it is

  • ~/Library/Application Support/Windsurf/Cache
  • ~/Library/Application Support/Windsurf/CachedData
  • ~/Library/Application Support/Windsurf/Code Cache
  • ~/Library/Application Support/Windsurf/GPUCache
  • ~/Library/Application Support/Windsurf/CachedExtensionVSIXs
  • ~/Library/Application Support/Windsurf/logs
  • ~/.codeium/windsurf/cascade/.cache

What it is

Windsurf, Codeium's AI editor, is built on VS Code and keeps the same kinds of caches in its Application Support folder: web and GPU caches, CachedData, cached extension packages and logs. Its Cascade agent also keeps a cache directory under ~/.codeium/windsurf.

Why it gets so big

These caches build up across app updates and extension installs, and the logs folder grows with every session you open.

Is it safe to delete?

Yes. These folders are regenerated automatically and don't hold your settings or installed extensions. Quit Windsurf first so it isn't writing to them; the next launch may be a little slower while the caches warm up.

See how much space it uses

du -sh "$HOME/Library/Application Support/Windsurf/Cache" "$HOME/Library/Application Support/Windsurf/CachedData" "$HOME/Library/Application Support/Windsurf/Code Cache" "$HOME/Library/Application Support/Windsurf/GPUCache" "$HOME/Library/Application Support/Windsurf/CachedExtensionVSIXs" "$HOME/Library/Application Support/Windsurf/logs" "$HOME/.codeium/windsurf/cascade/.cache" 2>/dev/null

Delete it by hand

Run in Terminal. Deleting cannot be undone, so check the paths first.

rm -rf "$HOME/Library/Application Support/Windsurf/Cache"/*
rm -rf "$HOME/Library/Application Support/Windsurf/CachedData"/*
rm -rf "$HOME/Library/Application Support/Windsurf/Code Cache"/*
rm -rf "$HOME/Library/Application Support/Windsurf/GPUCache"/*
rm -rf "$HOME/Library/Application Support/Windsurf/CachedExtensionVSIXs"/*
rm -rf "$HOME/Library/Application Support/Windsurf/logs"/*
rm -rf "$HOME/.codeium/windsurf/cascade/.cache"/*
