Peer-to-peer WebRTC connections with built-in signaling and discovery

Works across browsers, Node.js, and React Native.

- P2P servers. Listen for peer connections anywhere, even in the browser.

- Direct connections. Connect to peers across devices and networks.

- Built-in signaling. Automatic SDP/ICE exchange and negotiation.

- Identities. Shareable cryptographic addresses instead of IP addresses.

- Peer discovery. Announce and find peers using shared topics.

- WebRTC API. Use data channels, audio/video tracks and transceivers.

- Ready to use. Signaling, STUN and TURN configured by default.

I just found cloudflare conveniently has some free tier TURN and STUN server allowance.

Great work! Does this offer something beyond what https://trystero.dev/ provides?

Do I understand correctly that this is normal webRTC with a custom signaling server using private/public key cryptography, and STUN and TURN servers I can use?

That's always what these things are since p2p WebRTC doesn't exist.

Sure, but once a peer is attached, the goal isto match onthe p2p mesh, but the entry is always relau first

Single signaling server:

What happens to anybody who builds on this when you turn off your server in a few months time?

This is the example. When building out yours, you can configure your ports

At first glance, it seems extremely similar to PeerJS.

Just to make sure it's clear, this is not a fully in-browser solution; unfortunately an external STUN server is still required. Would be great if the browser gave us a way to discover peers fully in-browser, even just on a local network

It doesn't have built-in signaling and peer discovery, because that's impossible.

It does look kinda neat, though!

cyanydeez 14 minutes ago | parent

Its basically the same though. You stop at the relay, then connect to a peer to find other peers. Rther than the relay handing oht p2p, the relay just hands out peer-as-server.

So, sure, we are stiill straining for decentralization.
