Why PostgreSQL?

PostgreSQL is known for being:

  • Reliable – It’s been around since 1996 and is trusted by big companies, governments, and developers all over the world.

  • Free and Open-Source – You can use it, modify it, and share it without paying a dime.

  • Feature-Rich – From simple queries to complex analytics, PostgreSQL can handle it all.

What Can You Do With It?

  • Store data for web apps, mobile apps, or internal tools

  • Analyze large datasets using advanced SQL functions

  • Build APIs and connect PostgreSQL to other tools and services

  • Work with complex data like JSON, time zones, or even spatial (map) data

Pretty much everyone. From startups to global companies like Apple, Instagram, and Spotify—PostgreSQL is trusted by teams that need a solid foundation for managing data.
