Supabase + PostGIS

Deploy a production-ready PostgreSQL instance with the PostGIS spatial engine enabled in one click.

Supabase eliminates the DevOps overhead of managing geospatial infrastructure by providing a pre-compiled PostGIS extension on top of a dedicated Postgres instance. You get full access to 1,000+ spatial functions (like ST_Distance and ST_Within) and the ability to index geometry and geography columns using GIST. Because it integrates with the Supabase Realtime engine and GoTrue auth, you can stream live coordinate updates to your frontend while enforcing row-level security policies based on a user's physical location.
