Clean My Ubuntu

Clean My Ubuntu shows what’s taking up space on your Ubuntu computer and lets you clean it safely. It comes as a desktop app (GTK 4 / libadwaita) and a terminal app (cmu) that share one engine.

• Smart Scan: APT cache, unused packages, old kernels (a fallback is always kept), old Snap revisions, systemd journal, crash reports, thumbnails and the Trash
• Each browser and each app’s cache as its own choice
• Developer caches: npm, Yarn, pnpm, pip, Go, Cargo, Gradle, Maven, Conda, Docker and Podman
• AI tools: caches and old sessions of Claude Code, Codex, Gemini and more; downloaded Ollama, Hugging Face and LM Studio models listed one by one
• Uninstaller showing each app’s real size and when you last used it
• Space Lens, large and old files, duplicate finder, startup items, privacy cleaner
• Optional weekly automatic cleaning

Nothing is deleted until you’ve seen the list and confirmed. It uses Ubuntu’s own tools (apt, journalctl, snap) instead of deleting files by hand, and your own files go to the Trash so you can undo. No telemetry.
