Fluent Reader

A self-hosted RSS server gives you cross-device sync at the cost of running a server. For anyone who reads feeds on one or two computers, that cost is unnecessary.

Fluent Reader is the install-and-go option. 9,598 stars, BSD-3-Clause. It fetches feeds itself and stores everything locally with no backend at all.

Visible care went into its interface — it follows Windows' Fluent design language and is clean and comfortably spaced, which stands out among open-source tools where function usually outranks looks. Card, list and magazine reading layouts are provided, with thorough dark mode support.

Useful capabilities:

• Full-text retrieval for summary-only feeds, so articles are read in the app rather than in a browser.
• Keyword filters and rules by title, author or content that auto-mark as read, hide or highlight — useful for taming noisy feeds.
• Offline reading: fetched articles are stored locally and remain available without a connection, which suits commutes.
• Optional service sync. If you later stand up FreshRSS or Miniflux, or already use Inoreader or Feedbin, it connects as a client and syncs read state — so starting standalone and adding a server later is a viable path rather than wasted configuration.
• OPML import and export for interoperability with other readers.

To be clear about:

• Standalone mode does not sync across devices. What you read on the computer stays unread on the phone unless you attach a sync service. That is the core trade-off against FreshRSS.
• There is no mobile app. The author builds for desktop only; reading on a phone requires a sync service plus a separate mobile client.
• Development has slowed. The current release, v1.2.2, is from April 2026 with the most recent commit in May 2026. The functionality is complete and usable, but this is not a rapidly iterating project.

How to choose: desktop only and no interest in servers → Fluent Reader. Sync between phone and computer and willing to self-host → FreshRSS, with this or a mobile app as the client.
