❤️ FluentCleaner is donation-supported.
Im building FluentCleaner as a donation-supported project. Learning WinUI 3 and turning this into a real app was definitely not painless, but it has been a lot of fun too.
If you like the project and want to support future releases, donations really help keep it going

CCleaner without the crap. finally.

FluentCleaner is a modern Windows cleanup tool built with WinUI3 and powered by the winapp2.ini ecosystem.

Features

• Winapp2.ini support out of the box, ~3,700 entries, community-maintained, always fresh
• Blazing fast parse + scan pipeline
• Custom databases supported; drop in any winapp2-compatible .ini and it just works
• Modern WinUI 3 interface that doesn't look like it was designed in 2009
• Category-based cleaning so you actually know what you're deleting
• Lightweight, no installer, just runs
• No Avast. No toolbar. No "recommended partner offer". No telemetry. Not even a little bit. Ive checked 😄
• Hardened Winapp2.ini entry handling (better compatibility and edge-case handling) It is recommended to update the database from time to time (FluentCleaner > Settings > Database)
• Control the full cleaner via CLI
• Proper app icon, because details matter. Thanks to @https://github.com/naderi
• Registry Cleaner, Nope. Registry cleaners are snake oil. that tab exists to make a point, not clean anything. something actually useful will go there eventually

Optional: download this Extensions.zip asset for additional tools.
