BookWyrm is the Fediverse’s alternative to Amazon’s GoodReads. You can find out more about it on the official website at JoinBookWyrm.com ⧉ and there’s a project account on the Fediverse at @firstname.lastname@example.org ⧉ (also on RSS here ⧉).
BookWyrm servers let users keep track of which titles they’ve read, discover new books to read based on human recommendations (instead of algorithms), and publish their own reviews.
BookWyrm users can import their data from GoodReads, LibraryThing, StoryGraph, OpenLibrary and Calibre, and there’s also a book catalogue built-in (based on information from Wikidata ⧉ and another Fediverse service Inventaire ⧉) if people want to add titles by hand. There’s also support for barcode scanning.
Because it’s part of the Fediverse, people on Mastodon etc. can also follow BookWyrm users’ accounts and see BookWyrm reviews appear in their timeline.
Under the terms of the BookWyrm project software, anyone (except corporations) can start their own BookWyrm server, and there’s a list of existing servers to join at joinbookwyrm.com/instances ⧉. If you are a top tier patron, you can also get a managed hosting service ⧉ where BookWyrm’s lead developer personally maintains your BookWyrm server so that you don’t have to do any technical stuff.
