The short version
- Each has a real cost: Firestore the no-cost Spark plan caps Standard edition at 50,000 document reads, 20,000 writes and 20,000 deletes per day; MariaDB jSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions
- They diverge on capability: Firestore covers Document Model, MariaDB covers MySQL Compatibility.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Firestore
- The no-cost Spark plan caps Standard edition at 50,000 document reads, 20,000 writes and 20,000 deletes per day
- The Spark plan caps storage at 1 GiB and network egress at 10 GiB per month
- Charging is per document read, so a query returning many documents bills for every one of them
- Going beyond the free thresholds requires the pay as you go Blaze plan billed at Google Cloud rates with no fixed monthly ceiling
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

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.
SourceMariaDB: 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.
SourceMariaDB: 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.
SourceMariaDB: 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.
SourceMariaDB: 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.
