It's literally on Fluxer.

Pros:

• AGPLv3, WITHOUT a CLA
• Familiar Discord UI
• Text and voice channels
• Images, attachments, gifs
• Emojis, reactions
• Screensharing and video calls
• Main server runs decently fast
• Federation is coming
• Not based in UK or US

Cons:

• Only 1 dude working on it
• You can optionally buy Plutonium, which isn't necessarily bad, they need money, and the code stays Open Source™
• No mobile app yet (they're working on it)
• The main server has had some downtime... which I think are just growing pains
• I don't have friends to invite to Fluxer
