Free · Open source · Local-first

One reader. Every device.

Keryx is a local-first RSS reader. macOS-ready today, with Windows and Linux on the roadmap. Your feeds live on your device and sync through cloud storage you already own — no accounts, no servers, no tracking.

Completely free — no freemium, no trial, no ads.

Features

Everything you want from a reader, nothing you don't

Built for people who want to own their reading — fast, private, and yours.

  • Multi-device sync

    Keep your feeds in sync across devices via cloud storage you control (Dropbox or Google Drive).

  • Local-first

    No central server. Keryx works fully offline — sync is entirely optional.

  • Fast local search

    Instantly search article titles and content by keyword, right on your device.

  • Tags & folders

    Tags for cross-cutting labels, folders for hierarchical grouping — organize feeds your way.

  • RSS & Atom

    Supports RSS 2.0 and Atom 1.0; RSS 1.0/RDF is also loosely parsed.

  • OPML import & export

    Migrate to or from other RSS readers and back up your subscriptions.

  • Completely free

    No freemium, no trial period, and no ads. Ever.

  • Open source

    The source code is public and can be inspected or modified by anyone.

Private by design

No accounts. No servers. No tracking.

Keryx has no backend that the developer controls. Everything — subscriptions, articles, tags, settings — lives in a local database on your device.

Read the Privacy Policy
  • No analytics, telemetry, crash reporting, or ads — nothing is collected in the first place.
  • Optional cloud sync goes straight from your device to your own Dropbox or Google Drive, never through a developer server.
  • Every claim is verifiable against the open-source code.
