Free · Open source · Local-first
One reader. Every device.
Keryx is a local-first RSS reader. macOS, Windows, Linux, and Android ready today. 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, Google Drive, or OneDrive). On Android, Dropbox and OneDrive are supported.
-
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- The app includes 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 cloud storage, never through a developer server.
- Every claim is verifiable against the open-source code.
