Quick answer

Clean, ad-free Facebook feed with real-time content filtering

F-Droid repository metadata

SlimBook provides a clean, ad-free Facebook feed by wrapping Facebook's lightweight mobile web client with real-time content filtering.

Features: • Removes ads, sponsored posts, stories, and reels • Hides posts from unfollowed pages and unjoined groups • Filters "People you may know" and other suggestions • Post age filter — hide posts older than a chosen threshold • Author and group management — block specific sources • Background notification polling • Messenger support via messenger.com • Photo upload support • Video autoplay disabled (tap to play) • Pull-to-refresh • External links open in system browser • Persistent login across app restarts

SlimBook uses Facebook's WebLite interface which delivers lightweight server-rendered HTML. A small JavaScript filter identifies and hides unwanted content by text patterns, running continuously via MutationObserver to catch new content as it arrives.

No tracking. No analytics. No data sent to third parties. All communication is between your device and Facebook's servers.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
