Database: Supabase (PostgreSQL 15)

Supabase provides a production-ready PostgreSQL 15 environment with built-in Auth, Realtime, and instant REST APIs.

Supabase delivers a full PostgreSQL 15 instance with high-performance features like the MERGE command and 4x faster in-memory sorting. Every project includes a suite of integrated tools: PostgREST for auto-generated APIs, GoTrue for identity management, and Realtime for database change listeners. You get full superuser access to manage 50+ pre-installed extensions such as PostGIS for spatial data and pgvector for AI workloads. The platform handles the heavy lifting of infrastructure (backups, connection pooling via Supavisor, and scaling) while maintaining 100% portability with standard Postgres.
