What is all-about-rss?

ALL about RSS is a large, maintained catalog of almost everything related to RSS (Really Simple Syndication), the web standard that lets you subscribe to websites and receive updates without checking each site manually. Think of RSS as a universal inbox for content from any source that supports it: blogs, news sites, podcasts, YouTube channels, and more. This repository organizes hundreds of tools, services, and resources that revolve around that standard. The catalog is divided into clear sections. There are RSS readers for every platform: desktop apps for Windows, Mac, and Linux, mobile apps for iOS and Android, self-hosted servers you can run on your own machine, hosted services you can access from a browser, and even terminal-based tools for developers who prefer the command line. There are also RSS bots for messaging platforms like Telegram and WeChat that push feed updates directly into a chat. Beyond readers, the list covers tools for generating RSS feeds from sources that do not natively provide one. That includes tools to create feeds from Twitter, Instagram, YouTube, GitHub, Hacker News, and many other platforms. There are also tools for forwarding feed content to email, Kindle, Slack, newsletters, and social media accounts automatically. Other sections cover feed validators, feed search engines, workflow automation services that integrate RSS, customized visual themes for popular RSS reader software, free public server instances of common self-hosted readers, and an interactive chart showing how different tools connect to one another. The project is maintained by the @AboutRSS community and does not restrict itself to popular or open-source entries: any well-functioning, actively maintained service or tool qualifies for inclusion. The full README is longer than what was shown.
