Tone is an API that allows Northstar players to track their kill statistics : https://toneapi.github.io/ToneAPI_webclient/
If you want your server to appear on this website, you can download the server side mod from here
The server side mod will send kills data to Tone API, which will then process them.
You will have to set a personal token for the mod to work, please ask me for one on Discord
Alternatively, you can selfhost your own backend here
npm install
npm run serve
npm run build
npm run lint
