What TurbineProxy is

TurbineProxy is a free, open-source Rust database proxy for MySQL and PostgreSQL. It directs reads and writes according to query intent without requiring application code changes, and can run as a replica-aware router or in front of one database server. For replica routing, it lists round-robin and least-connections balancing and can exclude replicas past a lag threshold. Per-backend connection pools support multiplexing and configurable sizes. Security controls include SQL injection detection, per-user read-only enforcement, query allowlists, and AES-256-GCM encryption at rest. A web dashboard, Prometheus metrics, query analytics, a heatmap, and prebuilt Grafana dashboard JSON support monitoring. Its embedded MCP server offers seven tools, including slow-query analysis, N+1 detection, index advice, replica lag, and backend health. It supports VS Code Copilot, Claude Desktop, Cursor, and other MCP clients. Deployment options include binaries, Docker, Homebrew, AUR, .deb, and .rpm; the software is self-hosted under Apache-2.0 with no per-query fees. GTID-aware read-your-own-writes support is specified for MySQL 8.0 and later.
