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; Xero the Early plan caps you at 20 invoices and 5 bills per month, and the invoice limit counts both approving and sending
  • They diverge on capability: MariaDB covers MySQL Compatibility, Xero covers Bank reconciliation.

Where each one falls short

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

Xero

  • The Early plan caps you at 20 invoices and 5 bills per month, and the invoice limit counts both approving and sending
  • Invoices created by connected app partners count against the Early plan invoice limit
  • Multiple currencies, project time and cost tracking, employee expense and mileage claims and industry benchmarking are restricted to the top Established plan at $90 per month
  • Cash flow forecasting is capped at 30 days on Early and 60 days on Growing, with 180 days only on Established
  • Payroll is not included in any plan and costs an extra $36 a month plus $6 per employee or contractor through Gusto
  • Inventory Plus is a paid optional add-on rather than part of any plan
  • The advertised 90% off applies only to the first 6 months, after which the regular $25, $55 or $90 monthly price auto-renews
  • The introductory discount excludes add-ons, usage charges and payment fees
  • Payment fees apply to online invoice payments and to bill payments other than standard domestic ACH, and are billed on top of the subscription
  • Subscriptions are billed monthly with no annual payment option, and after upgrading you must wait one month before downgrading to a cheaper plan
  • Xero states subscription prices are increasing from October 1, 2026

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
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

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.
