What Sifty is

Sifty is a free, open-source maintenance tool for Windows, with a command-line interface and a full-screen terminal UI. It scans and cleans temporary files, browser caches, crash dumps, and other junk. Disk tools report volume usage, locate large files, and find duplicates with NTFS-aware handling. Sifty uninstalls applications through winget and checks for leftover files; it also supports batch uninstalling. For developer cleanup, it can target node_modules, build output, orphaned worktrees, and WSL2 disks. Users can manage startup items and services marked safe to disable, then turn those changes back on. Destructive commands preview changes by default and require `--apply` plus confirmation. Removed items go to the Recycle Bin and can be restored. Windows and key system locations, including Program Files, ProgramData, the drive root, and the user profile root, are protected from deletion. Applied deletions are recorded in an audit log under the user's Sifty application data directory. An optional AI assistant runs locally through Ollama; it can see file names, sizes, and paths, but not file contents, and cannot delete files. Sifty supports Windows 10 and 11 and is distributed through pipx, a standalone executable, Scoop, and winget.
