TAS Score: S3/3 — D4/5 · A3 / T2 (D4 not D5: MariaDB Corporation went through financial difficulties in 2023 — acquired by K1 Investment Management. Governance trajectory to watch.)

Alternative	Autonomy	Notes
PostgreSQL	A3 / T2	More powerful; preferred for new deployments
MySQL	A3 / T1	Oracle-owned original; commercial features gated

Trajectory

Direction: mixed

MariaDB was created to provide a community alternative to Oracle-controlled MySQL. The MariaDB Foundation provides independent governance. However, MariaDB Corporation (the commercial entity) went through financial difficulties in 2023 and was acquired by K1 Investment Management — a private equity firm. The Foundation remains independent but the corporate trajectory adds uncertainty.

Signal assessment:

Signal	Status	Evidence
License	✅	GPL-2.0; no changes
Feature gating	➖	Enterprise features exist but core is fully open
Self-hosting	✅	Self-hosting well-supported
Governance	⚠️	MariaDB Corp acquired by K1 (PE) in 2023; Foundation independent but watch
