Is MariaDB or Redis better?

Neither clearly leads. MariaDB starts at Free and Redis at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, MariaDB or Redis?

MariaDB starts at Free and Redis at Free.

Does MariaDB or Redis run on more platforms?

MariaDB runs on Linux, Unix, Windows, macOS. Redis runs on Linux, macOS, Windows.

Can I use MariaDB for free?

Both have a free tier, so you can try either at no cost before committing.

What is MariaDB best used for?

MariaDB is most often used for transaction processing, data storage, application backend, reporting. Of those, transaction processing and data storage are not what Redis is typically brought in for.

What can MariaDB do that Redis cannot?

MariaDB covers MySQL Compatibility, Aria Storage Engine, ColumnStore, Galera Cluster. Redis covers In-memory data store, Data structures, Pub/Sub messaging, Lua scripting.

The short version

Each has a real cost: MariaDB jSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions; Redis licensing changed from BSD to AGPL in 2025, impacting open-source usage
They diverge on capability: MariaDB covers MySQL Compatibility, Redis covers In-memory data store.

Where they differ

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

Redis

Licensing changed from BSD to AGPL in 2025, impacting open-source usage
All data must fit in memory, limiting scalability to available RAM
No built-in support for multi-tenancy
Limited transaction support compared to traditional databases

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.

Source

Redis: Is Redis open source?

Redis was open source under the BSD license since its inception in 2009 and has remained open source. However, in 2024-2025, Redis Labs changed licensing to source-available and AGPL, prompting the creation of Valkey, a BSD-licensed open-source fork.

Source

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.

Source

Redis: What is Redis used for?

Redis is an in-memory data structure store used primarily as a cache, database, and message broker. It provides high-speed data access for real-time applications, sessions, leaderboards, real-time analytics, and other use cases requiring fast data retrieval.

Source

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.

Source

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.

Source

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.

Source

MariaDB: 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.
