Right now, ShadowBroker is really optimized for 'blinking blip' real-time radar tracking (streaming the raw GeoJSON payload from the FastAPI backend directly to MapLibre every 60s), so we get as close to as smooth 60fps entity animations across the map.
Moving to something like Martin would be incredible for handling EVEN MORE entities if we start archiving historical flight and AIS data into a proper PostGIS database, but the trade-off of having to invalidate the vector tile cache every few seconds for live-moving targets makes it a bit overkill right now....
You can throw it on a server and run it for you to see (or anyone else if you trust people or dont care about losing your free API keys) It's just a standard Next.js and FastAPI stack, and there are Dockerfiles in the repo so it should be pretty straightforward to spin up on a cheap VPS (like a DigitalOcean droplet or Hetzner).
Honestly, if you just want to show it off to a few people, running it locally and exposing it with a Cloudflare Tunnel or Ngrok is probably the path of least resistance.
I WILL work on having a version to host it where users have to bring their own keys to see it in the future though
Did the terminal throw any Python FastAPI errors, or did it just serve the Next.js frontend? I'm going to push an update later today to show a prominent "Backend Disconnected / Missing API Keys" warning on the UI so it doesn't just look dead. Thanks for testing it!
