FediCraft
Federated network support for Minecraft
About this Mod
This mod enables better integration between Minecraft and federated networks (of note, ActivityPub), especially with standalone apps for federated networks.
On the client side, it allows clicking links to federated networks in general - as sent by the server - and opening them as per the Fedi Links Project (or see below). This is in addition to the existing, vanilla support for HTTP and HTTPS links. (This currently requires a DLL on Windows, shipped with the mod for x86 and x86_64. Sorry Windows on arm64 players, we do not currently know how to compile the DLL for Windows on arm64; we tried.) On the server side, it attempts to resolve ActivityPub handles into the appropriate ActivityPub links.
Fedi Links are preferentially opened in the user's standalone apps, if any, but they will be opened in the browser if no app is installed! This is made possible thanks to Fallback Protocol Handlers as specified by the Fedi Links Project. For example, an ActivityPub link would open in a Mastodon client and allow you to immediately interact with it, but if you don't have a Mastodon client, it'll open a read-only view in a browser instead.
The main goal of this mod is to persuade instances to have a protocol handler endpoint while also enabling fedi-related networking (meeting folks and sharing handles) for in-game events like modfest and blanketcon. Instance admins are encouraged to implement Fallback Protocol Handlers for players without an app installed. For Mastodon instances, this can be done with a patch. Akkoma instances can use the pull request instead.
List of ActivityPub instances that have implemented the Fedi Links fallback handler and agree to be listed here:
- portend.place (closed regs/single-user-ish)
List of third-party Mastodon-compatible clients known to be compatible with FediCraft:

- Tuba (Linux)
- Feditext (macOS)
