; Drizzle
: [[Drizzle (database server)|Drizzle]] was a free software/open source relational database management system (DBMS) that was forked from the now-defunct 6.0 development branch of the MySQL DBMS.<ref name="Clark 2011">{{cite web | last=Clark | first=Jack | title=MySQL fork Drizzle gets general release | website=ZDNet | date=2011-03-17 | url=https://www.zdnet.com/home-and-office/networking/mysql-fork-drizzle-gets-general-release/ | access-date=2016-01-03}}</ref> Like MySQL, Drizzle had a [[client/server]] architecture and uses [[SQL]] as its primary [[command language]]. Drizzle was distributed under version 2 and 3 of the [[GNU General Public License]] (GPL) with portions, including the protocol drivers and [[Database replication|replication]] messaging under the [[BSD licenses|BSD]] license.
; WebScaleSQL
: [[WebScaleSQL]] was a software branch of MySQL 5.6, and was announced on 27 March 2014 by Facebook, Google, LinkedIn and Twitter as a joint effort to provide a centralized development structure for extending MySQL with new features specific to its large-scale deployments, such as building large replicated databases running on server farms. Thus, WebScaleSQL opened a path toward deduplicating the efforts each company had been putting into maintaining its own branch of MySQL, and toward bringing together more developers. By combining the efforts of these companies and incorporating various changes and new features into MySQL, WebScaleSQL aimed at supporting the deployment of MySQL in large-scale environments.<ref>{{cite news

; OurDelta
: The OurDelta distribution, created by the Australian company Open Query (later acquired by Catalyst IT Australia), had two versions: 5.0, which was based on MySQL, and 5.1, which was based on MariaDB. It included patches developed by Open Query and by other notable members of the MySQL community including Jeremy Cole and Google. Once the patches were incorporated into the MariaDB mainline, OurDelta's objectives were achieved and OurDelta passed on its build and packaging toolchain to Monty Program (now MariaDB Plc).<ref>{{cite web |url=https://openquery.com.au/products/ourdelta |title=OurDelta |website=openquery.com.au |date=22 August 2017 |access-date=20 August 2021 }}</ref>
