About

FeedFlow is an open source RSS reader built for desktop — a fast, minimal timeline for your news, blogs, and feeds. No algorithms, no clutter, no noise.

A Desktop-First Reading Experience

  • Three-pane layout: sidebar, feed list, and article view — all visible at once
  • Switch to single-pane mode if you prefer a focused view
  • Keyboard shortcuts for everything — refresh with F5, navigate with arrow keys, mark as read with Ctrl+Shift+A
  • The app remembers your window position and size between sessions
  • Dark mode, light mode, and OLED black theme

Read Articles Your Way

  • Open articles in your default browser, or use Reader Mode for a distraction-free reading experience
  • Adjust text size and spacing in Reader Mode for comfortable reading on any screen
  • Prefetch and cache full article content for offline reading

Sync Feeds Across All Your Devices

  • Keep everything local, or sync with multiple backends
  • Cloud storage sync with Dropbox
  • Self-hosted and server sync with FreshRSS, Miniflux, Feedbin, or BazQux
  • Your feeds, read status, and bookmarks stay in sync across Linux, Windows, Android, iOS, and macOS

Stay Organized

  • Import and export feeds with OPML — migrate from any RSS tool
  • Block keywords to filter out unwanted content
  • Organize feeds into categories and bookmark articles for later
  • Search across all your feeds to find articles quickly

Built for RSS, Atom, and the Open Web

  • Supports RSS 2.0, RSS 1.0, and Atom feed formats
  • Add feeds by URL or browse curated suggestions
  • No account required to get started

Open source with an active community. Available on all major platforms. Translated into 25+ languages.
