Point to point secure chat
It's better on our website! We recommend going to our website instead of reading the below content. It's meant to be clearer and also looks better.
P2PSC is a simple command-line chat application that's based on sockets, and most importantly, doesn't rely on a main server or backend.
Chats are created by "peering" with other users. They must give you an IP address and port to connect to, and then all messages will be sent over a socket.
A guide to quickly creating a chat between two people not on the same network.
Both of you:
- Install P2PSC with
yarn global add p2pscor
npm install -g p2psc
- Download and set up Ngrok
p2psc ngrok 1337
ngrok http 1337in a seperate terminal
- Enter the url that Ngrok gave you (without the
https://) into P2PSC
One of you:
- Get the other's peer string; it should look something like
- Send it in chat
To download P2PSC the normal way from Node, just run one of the below commands depending on your preferred package manager.
yarn global add p2psc
npm install -g p2psc
If you want to download a compiled executable which could be useful if you're going to a summer camp and want to give others copies of the app to chat with one another across campus under the nose of the faculty and staff (seems oddly specific, doesn't it?), you can download it for various platforms from one of the below links:
p2psc and enter your hostname to start P2PSC. This hostname is what others will be able to use to connect to you.
To peer with someone else, just send
/peer HOST:PORT in chat.
Does it support group chats?
Yep! Just peer to multiple people and it'll work fine.
How secure is it?
Well, nothing is encrypted. But by default, it's only exposed to people on your local network and other people need both your IP and the port P2PSC is running on. To expose it to the public you'd need a service such as Ngrok, see the next question.
Can I use it with Ngrok to chat with other people across the web?
Why, yes! Just run P2PSC like this instead
p2psc ngrok SOME_PORT, and then run
ngrok http SOME_PORT. Then, in P2PSC when it asks for a host enter the url Ngrok gave you (without the
How does P2PSC choose ports? Can I choose my own?
P2PSC will find an available port with an amazing NPM package called
portfinder. And yes, you can choose your own! Just run
