Postgres

Open-source relational database that handles everything from side projects to billion-row production systems.

What are Postgres?

Postgres is an open-source relational database that's been battle-tested since 1986.

It stores your data in tables with rows and columns, but goes beyond basic SQL with features like custom data types, JSON support, full-text search, and geospatial queries through PostGIS.

Most builders use it as their default database choice. It runs on everything from a $5 DigitalOcean droplet to massive production systems at Uber and Instagram. You can self-host it or use managed services like Neon, Supabase, or Railway.

Free and open source. Managed hosting starts around $10/month for small projects.
