MySQL
FreemiumThe world's most popular open source database.
Published 29 May 2026 · Last updated 27 September 2026
Scores
Popularity5/5
The most widely deployed open-source relational database globally — powering the majority of web applications and the default choice in shared hosting and PHP stacks for decades.
Learning Curve2/5
GUI tools (MySQL Workbench, phpMyAdmin) and extensive tutorials make it highly accessible; basic SQL is straightforward but advanced features like stored procedures and replication configuration require more study.
Flexibility3/5
Covers standard OLTP use cases thoroughly; lacks some advanced SQL features PostgreSQL offers (partial indexes, richer JSON, table inheritance); plugin storage engines add flexibility for specific workloads.
Performance3/5
InnoDB delivers solid OLTP throughput for standard read-heavy workloads; query optimizer has historically lagged behind PostgreSQL and MariaDB for complex plans, and thread pooling requires the Enterprise edition.
Portability4/5
Available on every major cloud as a managed service (RDS, Cloud SQL, Azure Database); supported by every major ORM and language driver; minor SQL dialect quirks can require adjustments when migrating.
About MySQL
MySQL is an open-source relational database management system (RDBMS) first released in 1995 and now owned by Oracle Corporation. It is the 'M' in the classic LAMP stack and remains one of the most widely deployed databases on the planet — used by Facebook, Twitter, YouTube, Airbnb, and countless others at massive scale.
MySQL uses a client-server architecture and stores data in tables with rows and columns, enforcing relationships through foreign keys. The default storage engine, InnoDB, provides full ACID compliance, row-level locking, and native replication support. MyISAM is a legacy engine still used for read-heavy, non-transactional workloads.
MySQL is available as the free Community Edition (GPL) and as MySQL Enterprise Edition, a commercially licensed product from Oracle that adds enterprise monitoring, security plugins, backup tooling, and 24/7 support.
It is particularly dominant in PHP and web application stacks, pairs natively with WordPress, and is first-class in cloud-managed offerings from AWS (Amazon RDS for MySQL, Aurora MySQL-compatible), Google Cloud (Cloud SQL for MySQL), and Azure (Azure Database for MySQL).
Key Features
- Full ACID compliance via InnoDB storage engine
- Master-replica and group replication built in
- Rich SQL dialect with stored procedures, triggers, and views
- Broad connector ecosystem (Python, Java, PHP, Node.js, Go, .NET, Ruby)
- Cloud-managed on AWS RDS, Aurora, Google Cloud SQL, Azure Database
- JSON column type and multi-valued indexes for semi-structured data
- Point-in-time recovery and binary log-based replication
- Row-level locking for high-concurrency OLTP workloads
Pros
- Extremely mature, battle-tested at massive scale
- Huge ecosystem: tutorials, ORMs, tools, managed cloud offerings
- Excellent performance for standard OLTP read-heavy workloads
- Native replication makes high-availability setups straightforward
- First-class support in every major web framework and language
- Strong default in shared hosting environments — ubiquitous
Cons
- Fewer advanced SQL features compared to PostgreSQL (e.g. partial indexes, CTEs were late additions)
- Oracle stewardship raises open-source sustainability concerns for some teams
- Limited support for complex analytics / OLAP without a separate engine
- JSON support and window functions mature later than in PostgreSQL
- Strict mode quirks and charset/collation configuration can catch beginners off guard

Tech Stacks with MySQL
Python Web (FastAPI + React)
ProjectA clean separation of concerns: React on the frontend, FastAPI serving a typed REST API, and PostgreSQL for persistent storage (MySQL, MariaDB, and serverless Postgres hosts are also available). Docker keeps environments consistent.
HTMX + Django
ProjectA server-driven web stack where Django renders HTML templates and HTMX adds dynamic interactions without writing JavaScript. Ideal for teams that want fast iteration on CRUD-heavy apps and dashboards with minimal frontend complexity.
HTMX + FastAPI
ProjectA lightweight, fast Python stack. FastAPI serves HTML fragment endpoints, HTMX swaps them into the DOM, and Tailwind CSS is an optional styling addition. Great for modern server-driven apps with async Python backends.
Tools Related to MySQL
Works well with MySQL(4)
AWS offers Amazon RDS for MySQL (managed) and Amazon Aurora MySQL-compatible Edition (high-performance); MySQL on AWS is one of the most common database choices for web applications in the AWS ecosystem.
Hostinger provides managed MySQL databases bundled with shared and VPS plans, pre-configured for WordPress and PHP apps through the hPanel control panel.
MySQL is commonly self-hosted on Hetzner VPS instances as part of LAMP stacks or containerised application deployments; Hetzner's cost-efficient dedicated and cloud servers make it a popular European hosting target for MySQL.
Google Cloud SQL for MySQL is a fully managed MySQL service on GCP, supporting MySQL 5.7 and 8.0 with automated backups and replication; it is a straightforward path for running MySQL workloads on Google Cloud.
Integrates with MySQL(7)
MySQL and PHP are co-designed components of the LAMP stack; PHP's mysqli extension and PDO_MySQL driver were developed alongside MySQL, making them the canonical pairing for server-side web development.
Drizzle supports MySQL with a dedicated driver and a type-safe query builder.
Prisma supports MySQL out of the box with schema modelling, migrations, and a type-safe query client.
TypeORM supports MySQL through the mysql2 driver, with migrations and both Active Record and Data Mapper entities.
MySQL powers the overwhelming majority of WordPress installations; the WordPress database schema, wpdb class, and plugin ecosystem are all built around MySQL's query syntax and behaviour.
Directus supports MySQL as its database, introspecting existing tables into its REST and GraphQL APIs and admin app.
Alternatives to MySQL(5)
Both are full-featured open-source relational SQL databases with ACID compliance and broad language support; PostgreSQL offers richer SQL features and a powerful extension system while MySQL prioritises simplicity and read performance in traditional web stacks.
MariaDB was forked from MySQL by its original developers in 2009 and remains a drop-in replacement; both share the same SQL dialect and connector ecosystem but diverge in licensing model, query optimizer, and storage engine lineup.
Plain MySQL is free to run on any server; PlanetScale hosts MySQL on Vitess with horizontal sharding, deploy requests, and online schema changes, on paid plans only.
Both are relational SQL databases but serve very different deployment contexts; MySQL runs as a dedicated server for multi-client workloads while SQLite is embedded and file-based, suited for single-process or local applications.
Often compared when choosing a database for web backends; MySQL provides strict relational schemas and referential integrity while MongoDB offers flexible document storage — the right choice depends on data model and query patterns.
