MySQL or PostgreSQL: which database should you choose?

formulatux teamAuthor 5 Sep 2026Published 5 min readLength

Both are excellent, free and widely supported. The right choice comes down to the kind of data and features you need.

Almost every web application stores its data in a database. Two open-source options dominate: MySQL (and its sibling MariaDB) and PostgreSQL.

MySQL and MariaDB

Fast, simple and available on practically every host. They are the default for WordPress, Laravel projects and many e-commerce platforms, and they handle read-heavy websites very well.

PostgreSQL

Known for strict standards, advanced features and reliability with complex data. It shines with complicated queries, reporting, geospatial data (PostGIS) and flexible JSON fields.

Quick guide

  • Standard business website, CMS or shop: MySQL or MariaDB.
  • Analytics, complex reporting or location data: PostgreSQL.
  • Unsure: either will do the job, and a good framework hides most of the differences.

What matters more than the brand

Good table design, sensible indexes, regular backups and monitoring. A well-designed database on either engine will serve you well.

The bottom line

Do not agonise over this choice. Pick the one your team knows best and your host supports well, and invest your effort in good design.
