I wanted to run a Mastodon instance for quite a while but loathed the idea of all of its complex components. I stumbled upon this project and it has been amazing!

Requirements: Elixir and Postgres

It is so lightweight it can run on a Raspberry Pi, and it’s not even fully optimized yet. I can also continue to use my favorite Mastodon mobile client because they implement the Mastodon API as well. This significantly lowers the barriers for entry into running your own server in the Fediverse.
