Self-host Maps with Protomaps and Supabase Storage

Protomaps is an open source map of the world, deployable as a single static file on Supabase Storage, allowing users to extract areas from the world map and compress them into a single static PMTiles file. Users can then upload these files to Supabase Storage, where they can be rendered using MapLibre GL or Leaflet, and accessed with restricted permissions through Supabase Edge Functions, which enable secure server-side access control.
