MariaDB: Open-source relational database, MySQL-compatible

The world's most advanced open source relational database
As of 30 August 2026, PostgreSQL is free to use. PostgreSQL is a powerful, open source object-relational database system with over 35 years of active development. Softwr lists it under Databases. PostgreSQL is made by PostgreSQL Global Development Group, launched in 1996, available on Linux, Windows, macOS.
Overview
PostgreSQL is a powerful, open source object-relational database system with over 35 years of active development. It has earned a strong reputation for reliability, feature robustness, and performance. PostgreSQL supports advanced data types, full ACID compliance, and extensibility through custom functions, data types, and operators.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about PostgreSQL.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for PostgreSQL, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
