Switching from Twitch to Owncast

Run `docker run -p 8080:8080 -p 1935:1935 -v $HOME/owncast-data:/app/data owncast/owncast`. Set the RTMP stream key in the admin panel; point OBS or Streamlabs at `rtmp://your-host:1935/live` and start streaming. Owncast ships with built-in chat (auth via Fediverse follow or guest), customizable themes, and Fediverse notifications when you go live so Mastodon followers get pinged. There's no backfill — past streams stay on Twitch unless you download VODs and host them on a separate site.

Good fit for: Streamers who want a Twitch-like single-channel experience under their own domain with no platform cut.
Weak at: No multi-channel directory or discovery; chat is single-room (no IRC-style rooms or Twitch's emote economy).
