Source: https://mariadb.org
What does MariaDB integrate with?
We have confirmed 14 integrations for MariaDB, including MariaDB Connector/C, MariaDB Connector/Node.js, MariaDB Connector/ODBC, MariaDB Connector/J, MariaDB Connector/Python, MariaDB Connector/R2DBC, MySqlConnector for ADO.NET and ADO.NET Driver for MySQL, plus 6 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.

What security certifications does MariaDB have?
We have independently confirmed GDPR for MariaDB. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as MariaDB not holding them. Always confirm compliance directly before you rely on it.
Is MariaDB open source?
Yes. MariaDB is published under the GPL-2.0 licence, a copyleft licence, so check its terms before embedding it in a closed-source product. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for MariaDB, not the verdict.
