abuuba organization abuuba is a fediverse server written in [Elixir](https://elixir-lang.org/) and [Phoenix](https://www.phoenixframework.org/). It speaks [Mastodon](https://joinmastodon.org/)'s protocols: ActivityPub for federation and the complete Mastodon client API, all 289 endpoints, so existing apps work unchanged. It exists for one reason: **Mastodon is too slow.** Other organization https://vutuv.de/abuuba Koblenz DE https://vutuv.de/abuuba.json https://vutuv.de/abuuba.txt https://vutuv.de/abuuba.md https://vutuv.de/abuuba.xml abuuba https://vutuv.de/organizations/abuuba/posts/01a05699-c756-7800-825b-461901fc39e7 2026-08-31 # abuuba 1.0 is out A Fediverse server built with Elixir and Phoenix.
