| Compare | MariaDB.org | PostgreSQL |
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | Engineering/DevOps teams with database administration skills who want no license fees | Engineering teams with SQL skills |
| Who it's not for | Non-technical founders and small businesses tracking customers, contacts, or inventory . this is a server database that requires setup, patching, and backups; use a spreadsheet or a simple SaaS tool instead | Non-technical teams that just need a shared spreadsheet |
| Privacy | MariaDB is mature and the Foundation maintains a published security policy aimed at fixing critical bugs quickly, but the record shows a steady stream of CVEs . including multiple remote-code-execution vulnerabilities . and community edition users are responsible for their own patching cadence.⁹ | Mature and actively patched . but 2025-2026 brought real CVEs, including one exploited in the wild. |
| Public sentiment | Users broadly like it: G2 and Capterra reviewers praise performance, security, and ease of use, Software Advice reviewers call it faster than MySQL, and Reddit users report it benchmarked ~20% faster than competing databases.³ | Developers consistently praise Postgres as robust, fast, and the default relational choice; the friction is operations, not the engine. |
| Biggest gotcha | Community edition users must track and apply security fixes themselves . multiple remote-code-execution CVEs have affected MariaDB over the years, and falling behind on versions is a genuine breach risk⁸ | CVE-2025-1094 saw real-world exploitation; patching discipline is mandatory. |
