Why is my Windows drive full? Free space safely, within limits you set. Never deletes permanently.
See why your Windows drive is full, and free space safely.
Sparewise finds the space that developer and AI tools quietly fill: package caches, local AI models, Docker and WSL disks, browser and editor caches, plus ordinary Windows clutter. It tells you what each item is and whether it comes back by itself. It frees space only when you say so, and anything it moves can be put back.

Windows may warn the first time ("Windows protected your PC") because Sparewise is not code-signed yet. Choose More info → Run anyway. Each release lists SHA-256 checksums, so you can check that a download is the genuine one.
Sparewise is also an MCP server, so Claude, Cursor, VS Code, Claude Code and Codex can ask why your drive is full, plan a cleanup and, only within limits you set, apply it. They can never delete anything permanently.

Is it free? Yes, everything is free to use today. Later versions may add paid features; the version you have keeps the terms it came with (see LICENSE).
Where is the source code? Sparewise is closed source. The "Source code" links that GitHub adds to every release contain only this README and the license files, not the program.
Does it need administrator rights? No. The few extras that use Windows' own admin tools (the fast drive map, Disk Cleanup) ask first, and you can say no.
Something went wrong or looks wrong? Choose Report a problem in the app, or open an issue. Questions and ideas are welcome in Discussions.
