ProxySQL is a high-performance SQL proxy for MySQL, PostgreSQL, and related ecosystems. It sits between applications and databases as a database traffic management layer. Its goal is to help scale database infrastructure without changing the application stack or database engine, addressing operational needs such as connection management, traffic routing, failover, observability, and multi-cluster governance.
In terms of features, ProxySQL focuses on high-throughput, low-latency connection handling, real-time health monitoring, failover detection, and seamless traffic redirection. It also provides real-time traffic patterns and query performance metrics, making it suitable for teams that want to move database access control forward into the proxy layer. Compatibility is one of its major selling points: it natively supports the MySQL and PostgreSQL wire protocols, covering MySQL 5.7 to 9.x, PostgreSQL 13–18, MariaDB, Percona, Aurora, RDS, Google Cloud SQL, Azure Database, TiDB, Vitess, CockroachDB, YugabyteDB, Neon, Supabase, Timescale, and more. ClickHouse can also be accessed via the MySQL protocol.
The project was first released as open source under GPLv3 in 2013. The Community edition is labeled as Always open source and includes ProxySQL Core Features, making it suitable for small projects and feature evaluation. On the commercial side, there are Professional and Enterprise plans: the former targets production environments and includes 24x7x365 support, high-priority bug fixes, architecture design, and Web UI Administration; the latter is designed for large organizations and offers SLA, health monitoring alerts, custom feature development, and more. Specific pricing is not public and requires contacting sales.
The main advantages are broad protocol compatibility and extensive database ecosystem coverage, making it well suited to heterogeneous MySQL/PostgreSQL environments. Its open-source core lowers the barrier to evaluation, while commercial services cover support, DBRE, consulting, training, and custom module development. The downsides are that advanced support and SLA depend on commercial subscriptions, pricing transparency is limited, and as an infrastructure component, deployment, tuning, and troubleshooting require strong database operations expertise. The collected content does not show detailed documentation or API/SDK specifications.
ProxySQL is suitable for DBAs, SREs, platform engineers, and architecture teams, especially in production environments that need read/write splitting, connection pooling, failover, and multi-cloud database entry-layer governance.
