Plamenu

Plamenu is the upcoming 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, snappy Peertube 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.
