The short version
- Only MariaDB has a free tier, so it costs nothing to try first.
- Each has a real cost: MariaDB jSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions; Privacera the company is mid-rebrand to Trust3 AI as of March 2026, so documentation, contracts and support channels are in transition and buyers should confirm which entity and which product name their agreement actually names.
- They diverge on capability: MariaDB covers MySQL Compatibility, Privacera covers Centralised policy authoring.
- Prices and features above were last checked on 31 August 2026.

Privacera

- A bank that must produce a single access audit across its analytics estate for a regulator without stitching together per-engine logsnot MariaDB

- A team exposing governed data to LLM applications that needs the same row and column restrictions to apply when an agent queries on a user behalfnot MariaDB
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
MariaDB
- JSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions
- Galera Cluster maximum performance limited to the slowest node in cluster
- InnoDB tables limited to 1,017 columns and 64 secondary indexes
- Transaction size limits in Galera (128K rows and 2GB by default)
- Less strict SQL type checking than PostgreSQL; allows implicit conversions
Privacera
- The company is mid-rebrand to Trust3 AI as of March 2026, so documentation, contracts and support channels are in transition and buyers should confirm which entity and which product name their agreement actually names.
- Investment is visibly shifting towards agentic AI governance, which raises a fair question about how much engineering continues to go into the classic data access governance modules that most existing customers actually bought.
- Native enforcement depends on each engine supporting the policy constructs you need, so what you can express on Databricks may not be enforceable identically on a less capable source, and coverage must be verified source by source.
- It sits between the data platforms and their own governance features, and as Databricks Unity Catalog and Snowflake native governance mature, single-platform customers find the case for a separate layer weakening.
- Pricing is unpublished and scales with connected sources, so an organisation that keeps adding data platforms discovers the governance layer cost grows alongside the platform costs it was meant to rationalise.

Answered from the vendors’ own pages
MariaDB: Is MariaDB completely free and open source?
Yes. MariaDB Server is licensed under GPLv2 and guaranteed to remain perpetually free and open source, independent of any commercial entities.
SourcePrivacera: Did Privacera merge with Immuta?
No. They remain independent competitors, and Privacera still publishes comparison material against Immuta. What did happen is a rebrand to Trust3 AI announced in March 2026.
MariaDB: Is MariaDB backward compatible with MySQL?
Yes. 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.
SourcePrivacera: Is it the same as Apache Ranger?
It is built on Ranger by Ranger creators, but it adds multi-engine enforcement, discovery, a managed cloud option and support. Ranger alone does not cover Snowflake or cloud storage in the same way.
MariaDB: What are the storage engine options in MariaDB?
MariaDB 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.
SourcePrivacera: Does it slow down queries?
It pushes policy into the underlying engine rather than proxying, so query execution stays native. Policy synchronisation, not query latency, is the usual operational concern.
MariaDB: How much does MariaDB cost?
MariaDB Community Server is completely free to download and use. MariaDB offers paid enterprise support and managed cloud services for organizations needing professional support.
SourcePrivacera: What does it cost?
Not published. Quoted by connected sources, user count and whether you self-manage or use Privacera Cloud. A free trial of the cloud product is available.
MariaDB: Does MariaDB support native JSON storage?
MariaDB 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: What scaling options does MariaDB provide?
MariaDB 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.
