It appears to be P2P, so, just like federated protocols, they are good in my book compared to centralized silos.
But I have yet to find a P2P chat protocol that works well in practice on mobile (energy efficiency/battery usage is a real concern, and mitigating it in practice means losing the benefits of P2P without the advantages of federated).
SimpleX is not purely P2P as there are servers that forward the messages. The battery consumption is still too high with SimpleX, but that can and is being worked on
The site is https://simplex.chat . It uses it’s own simplex protocol. There are no permanent user identifiers with SimpleX which gives a lot more privacy and independence. Here’s a comparison: https://github.com/simplex-chat/simplex-chat/blob/stable/docs/SIMPLEX.md#comparison-with-other-protocols
