TURN relay is used to transfert all datas while the signaling server is here to find your external IP (STUN) and send all known peers id/ips to clients so they can connect to each others. The signaling server is not used to send datas. |

Bro I know what it is. I don’t want to pay for an additional websocket
server. The idea is to create a temporary turn connection to set up the
signaling between peers. Due to firewalls I have to pay for a turn server
anyway.

Can't you just start the 2 apps on the same server ? |

They need to be scaled - since they aren't stateless this is very expensive |

I don't use TURN server, you mean you're actually paying for this kind of service ? Its for a professional app ? TURN server needs to have enought power/bandwidth to handle packet redirections, but signalling server shouldn't consume that much, or maybe you have thousands of users ? I've setup my own signaling server, I know some people used public hosts to setup their signaling server, they use some service like pastbin or something so they modify the only file when they connect then read it again to get all peers, maybe you can setup something like that too ? I built multiple classes that can dispatch the peer infos on UDP broadcast, WebSocket and more. |

Yes many thousands of users

Maybe you can try libtorrent for peer signaling ? |

You need to have a signaling server of some kind as you need to let both devices know the others IP address. This is two strings you need to exchange every time two devices decide to connect to each other and it is really not a lot of work. 80% of the SDP is the same, so with some hacks you can store just the candidates themselves. Your cheapest option is going to be some kind of database backed store with an HTTP frontend. This isn't free, like anything else. You'll likely be able to get away with Cloudflare workers and it'll be a few bucks a month or if you're really good at what you do, one PHP/SQL server. You can try libtotrent, but any time you try to piggy back off of others it'll be an unreliable (and insecure) solution. As for the turn server, it will be required the moment you try to use it behind a non-cheapo-residential firewall, but that's like 10-20% of residential connections. But turn compute should be very cheap so most of your costs will be bandwidth, not compute. |

No, signaling is not just a relay, it's more like a meeting point for the two peers to exchange connection information before establishing it.
No, TURN only allows to allocate a public-facing network port and relay the traffic, it can't serve as meeting point.
Signaling should be more or less integrated with your own application backend to handle authentication, peer discovery, rooms, etc. It can be performed over the protocol of your choice, you don't have to use WebSockets. |

We have a central database to act as the meeting point but the cost of
funneling signaling through it is prohibitive. All that’s needed is a relay

Wouldn't it be possible to use the TURN server (that's already required)
to transmit signaling messages?
No, TURN only allows to allocate a working network port and relay the
traffic, it can't serve as meeting point.
Why pay for both?

Another option I was considering was to elect one of the peers as the
signaling server, use the database to signal with that peer, and then use a
datachannel relay for the rest of the signaling.
