Introduction

As far as I know, the software used by Fediverse, a decentralized social networking site, makes information public due to its decentralized nature, and as a result, it's often possible to obtain feeds of the latest information via RSS.

However, the extent to which this is possible varies depending on the software's capabilities and features, and I was interested in the functionality of each piece of software, so I decided to write this article to research and summarize the state of RSS on Fediverse, including its URL structure.

This article is based on a pioneering article titled "Finding Fediverse Feeds" that appeared on the website Hyperborea: Kelson Vibber.

Stream RSS feeds to Your Fediverse Feeds

A well-known method of distributing RSS feeds from the web to ActivityPub is software (server) called RSSParrot, which was created for that purpose.

In addition, in the Japanese-speaking world, there is a public Mastodon instance called the RSSフィードbot鯖, which is dedicated to RSS Bots and is also widely used.
