host your own

Want a canvas for just your friends? Run your own copy of this site. Badges installed from your site show your canvas.

Fork phthallo/supercon.
Deploy server/ on any host that runs containers (Coolify, Fly.io, a VPS). docker compose up in server/ starts it with a Postgres database.
Serve it over https. The flasher and USB access only work on secure pages.
Set the environment variables below.
Open /install on your site and install as above.

`DATABASE_URL`	a `postgres://` URL. The compose file sets it.
`ADMIN_PASSWORD`	password for `/admin`, where you add text and images. Admin is off without it.
`PAINT_COOLDOWN`	wait between paints, like `30s`. `0s` turns it off.
`WIFI_SSID`, `WIFI_PASSWORD`	a network to prefill on this page.
`TRUSTED_PROXY_HEADER`	header holding the visitor's IP behind a proxy. Defaults to `X-Forwarded-For` in the Docker image.

To change the badge app or the full image, edit the repo and run .venv/bin/python tools/build.py supercon ink --release, then redeploy. The README covers setting up the tools.
