About The Project

This is the relay server for CrewLink, an Among Us proximity voice chat program. I am currently hosting a server at, but if you want a more reliable option I would suggest to deploy this repository yourself.

Environment Variables

Optional environment variables:

  • PORT: Specifies the port that the server runs on. Defaults to 443 if HTTPS is enabled, and 9736 if not.
  • ADDRESS (REQUIRED): Specifies the server domain
  • NAME: Specifies the server name
  • HTTPS: Enables https. You must place privkey.pem and fullchain.pem in your CWD.
  • SSLPATH: Specifies an alternate path to SSL certificates.

Deploy to Heroku

To get up and running quickly, you can deploy to Heroku using the button below


This will deploy an instance of the crewlink-server. You can get the URL of your server by using the app name that you gave when you launched the app on heroku and appending You can also find the URL of your server by going to "Settings", scrolling down to "Domains", and removing the https:// and trailing slash from the url. Using this URL, follow step 4 of the installation instructions to connect your client to your server instance.

Docker Quickstart

Run the server with Docker by running the following command:

docker run -d -p 9736:9736 ottomated/crewlink-server:latest

To change the external port the server uses, change the first instance of the port. For example, to use port 8123:

docker run -d -p 8123:9736 ottomated/crewlink-server:latest
