Plamenu

Plamenu is an experimental ActivityPub server, written in Rust.
It's roughly Mastodon-shaped (including relays, quotes and collections), with a bunch of familiar features slapped on top, like Lemmy-compatible groups, *oma and *key-compatible emoji reactions, markdown, local visibility, Peertube/Owncast broadcast playback, and more to come. Most of the clients are supported, Phanpy and Tusky recommended.

This instance exists to test it in real-world conditions, it will be decommissioned later, as we get closer to the release.
Sign up is available via review or invitation; no email address is required. I invite you to register and help with testing.
