Overview

JARR (Just Another RSS Reader) is a free, open source, self-hosted RSS and Atom feed aggregator that lets users follow blogs and news sites from a single web interface they fully control. It began as a fork of Cedric Bonhomme's Newspipe project and is now maintained by a developer known as jaesivsm, distributed openly on GitHub for anyone to self-host.

As a community-maintained, single-developer-led project rather than a commercial product, JARR appeals to self-hosting enthusiasts and technically comfortable users who value data ownership and independence from centralized feed reader services like Feedly.

Key Features

JARR presents a classic three-column reading layout: categories and feeds on the left, an article list in the middle, and full article content on the right. For feeds that only publish truncated summaries, it uses Readability-based content extraction to pull and display the full article text inside the app itself.

A queue-based crawler periodically polls subscribed feeds for new content, and filtering options let users quickly surface feeds with unread items or fetch errors. The interface is mobile-responsive for use on tablets and phones, and the app is built on a Python 3 and Flask backend with a ReactJS frontend.

Pricing

JARR is entirely free and open source, with no license fees, subscription tiers, or paid features; the only cost involved is whatever server or hosting infrastructure a user chooses to run it on, typically via Docker on a home server or low-cost VPS.

There is no commercial entity behind JARR selling support contracts or hosted plans, so users rely on the public GitHub repository, documentation, and community for setup help; a public jarr.info instance is available to try the reading experience before self-hosting.
