FediCraft

On the client, FediCraft turns federated links in chat and in-game text into clickable links. When a player clicks an ActivityPub link, such as a Mastodon profile or post, the mod tries to open it in a standalone app installed on the computer. If no app is found, the link opens in a read-only view in the browser instead. Server-side attempts to resolve ActivityPub handles are also made so the right ActivityPub link can be offered.

The mod is built around Fallback Protocol Handlers from the Fedi Links Project, which lets instances offer a fallback so players without an app still see the content. Instance admins are encouraged to implement this, and Mastodon instances can do so with a patch, while Akkoma instances use a pull request. A list of ActivityPub instances that implement the fallback handler is kept, along with third-party Mastodon-compatible clients known to work with FediCraft. Windows builds ship a DLL for x86 and x86_64, and Windows arm64 players must compile the DLL themselves.

FediCraft requires Fabric API and runs on Fabric or Quilt for 1.19.2 – 1.20.4, with the latest file 0.2.7+1.20 for 1.20.4 released on 2023-10-28. Servers do not need it; each player installs it for their own game. The code is licensed under MIT OR Apache-2.0 and is not open source; public links exist for the source code and issue tracker.
