I'm the Trystero author and I'd say both libs attempt to accomplish the same goal but with very different APIs. One key difference is PeerJS uses a single centralized server by default for matchmaking, whereas Trystero offers lots of flexibility and redundancy, using various signaling connections in parallel.

I've been exploring PeerJS (https://peerjs.com/) recently. This seems like a similar concept. Would it give me anything that PeerJS doesn't?
