X-callback-url Scheme

RSSBud has implemented the x-callback-url protocol, which provides a standardized means for iOS developers to expose and document the methods they make available to other apps via custom URL schemes.

You can open the following URL to let RSSBud analyze the provided URL and return the RSS feed chosen by the user:



  • url The URL you want RSSBud to analyze


  • feed_title The name of the RSS feed chosen by the user
  • feed_url The URL of the RSS feed chosen by the user

PopClip Extension

If you happen use both RSSBud and PopClip on macOS, here's a handy extension that can be used to analyze selected URLs with RSSBud. Simply select everything in the code block below and you will see an option to install the extension in PopClip.

name: RSSBud
icon: iconify:ph:rss-bold
url: rssbud:///analyze?url=***

Notes for Building from Source

The core functionality of RSSBud comes from RSSBud Core, a sub-project written in JavaScript. The code is mainly referenced from RSSHub Radar.

Make sure you have Node.js installed before you build with Xcode.

If you wish to use the action extension, please set up your own App Group in both the iOS and Action Extension targets and modify RSSBud.appGroupIdentifier accordingly.


RSSBud’s functionality is largely powered by rules from two open-source projects. Please consider contributing to the appropriate rules if a particular feed can’t be discovered by RSSBud.

  • RSSHub Radar Rules are created and maintained by the RSSHub community. They are used to discover RSSHub feeds.

    Submit new RSSHub Radar rules

  • RSSBud Rules are a superset of RSSHub Radar rules. The extended schema allows non-RSSHub feeds (e.g. official RSS feeds that are not discoverable by parsing HTML) to be discovered. Please consider contributing to RSSHub Radar rules first if the feed is an RSSHub feed.
