TurbineProxy is a database proxy written in Rust that sits between your application and your MySQL or PostgreSQL servers.
It handles connection pooling, automatic read/write splitting, query routing, health checks and failover — all configured with a simple TOML file and manageable via a web dashboard without restarts.
Some things it does out of the box:
<ul>
<li>Routes SELECT queries to replicas and writes to primary automatically</li>
<li>Protects against SQL injection at the proxy layer</li>
<li>Monitors replica lag and removes unhealthy backends from rotation</li>
<li>Records query fingerprints, P95/P99 latencies, and slow queries — no extra tooling needed</li>
<li>Exposes Prometheus metrics and a Grafana dashboard</li>
<li>Includes an MCP server so AI assistants can query your proxy’s live metrics and docs directly</li>
</ul>
Supports MySQL 8.0+, MariaDB 10.6+, and PostgreSQL 14+. Ships as a single binary, Docker image, or Helm chart.
100% open source (Apache-2.0) and free.
