Open J Proxy
Building the future of database connectivity for Java applications
To empower developers and organizations to build scalable, reliable Java applications without the constraints of traditional database connection management. We believe in open source, freedom from vendor lock-in, and providing enterprise-grade solutions accessible to everyone.
In modern cloud-native architectures, microservices need to scale elastically to handle varying loads. But traditional connection pooling creates a critical bottleneck: as services scale up, each instance maintains its own database connections, leading to connection storms that can overwhelm and crash database systems.
Open J Proxy was born from real-world pain points experienced by teams building scalable Java applications. The project started as an internal solution to enable true elastic scaling while protecting critical database infrastructure.
By introducing a JDBC Type 3 architecture with server-side connection pooling, OJP decouples application scaling from database connection management. Applications can scale freely while the database sees a stable, controlled number of connections.
We believe in transparency, community collaboration, and giving back. Open J Proxy is 100% open source with no hidden features or artificial limitations.
No vendor lock-in. No cloud-specific dependencies. OJP works everywhere: AWS, Azure, GCP, on-premises, or any infrastructure you choose.
We obsess over performance. Built on proven technologies like HikariCP and gRPC, OJP delivers enterprise-grade performance with minimal overhead.
Your database is critical infrastructure. We build OJP to protect it with circuit breakers, backpressure, and comprehensive monitoring.
Powerful doesn't mean complex. OJP requires zero code changes and minimal configuration. Get started in minutes, not months.
We listen to users, welcome contributions, and build together. The best ideas come from those who use OJP every day.
Built on proven, industry-leading technologies
