You can easily have this running on your own server.
- Install Node
- Clone this repo
- run
npm install
in the directory you cloned - run
npm start
to start the Express server (default port: 3000, you can use iptables to forward port 80 traffic to 3000) - If you're running this on a VPS, you probably want to use forever service. It will start the server on boot and also restart if problems arise.
