PostgreSQL: More advanced SQL standards compliance and stricter type checking; preferred for complex queries

The open source relational database for the enterprise
As of 30 August 2026, MariaDB is free to use. MariaDB is a community-developed, commercially supported fork of MySQL. Softwr lists it under Databases. MariaDB is made by MariaDB Foundation, launched in 2009, available on Linux, Windows, macOS.
Overview
MariaDB is a community-developed, commercially supported fork of MySQL. It is intended to remain free and open-source, with enhanced features, improved performance, and better storage engines compared to MySQL. MariaDB maintains compatibility with MySQL APIs and commands.
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 MariaDB.
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.

MySQL: The predecessor; direct compatibility but updated independently by Oracle


Microsoft SQL Server: Enterprise database with different licensing model and Windows-native tools


Oracle Database: Enterprise-grade database with advanced features and different scaling approach

Each answer names the page it came from, so you can check it rather than take our word for it.
Yes. MariaDB Server is licensed under GPLv2 and guaranteed to remain perpetually free and open source, independent of any commercial entities.
SourceYes. MariaDB was designed as a drop-in replacement for MySQL. Every application, driver, and configuration that worked with MySQL works with MariaDB without code changes.
SourceMariaDB supports multiple storage engines including InnoDB (transactional, default), Aria (crash-safe, good for read-heavy workloads), and MyISAM. The Aria engine is faster than InnoDB for certain read-heavy queries and full table scans.
SourceMariaDB Community Server is completely free to download and use. MariaDB offers paid enterprise support and managed cloud services for organizations needing professional support.
SourceMariaDB stores JSON using text fields (the JSON type is an alias for LONGTEXT), not as a native binary type like MySQL does. JSON support exists but is less sophisticated than MySQL's JSON functions and syntax.
SourceMariaDB supports both scaling up (more cores, memory, storage) and scaling out (read replication, Galera Cluster with multi-node replication). However, Galera Cluster performance cannot exceed the slowest node in the cluster.

Softwr does not host reviews and shows no star rating for MariaDB, 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.
