The java implementation of Apache Dubbo. An RPC and microservice framework.
Apache Dubbo Project
Apache Dubbo is a powerful and user-friendly Web and RPC framework. It supports multiple language implementations such as Java, Go, Python, PHP, Erlang, Rust, and Node.js/Web.
Dubbo provides solutions for communication, service discovery, traffic management, observability, security, tooling, and best practices for building enterprise-grade microservices.

🧱 Architecture
- Communication between consumers and providers is done via RPC protocols like Triple, TCP, REST, etc.
- Consumers dynamically discover provider instances from registries (e.g., Zookeeper, Nacos) and manage traffic using defined strategies.
- Built-in support for dynamic config, metrics, tracing, security, and a visualized console.
🚀 Getting Started
📦 Lightweight RPC API
Start quickly with our 5-minute guide
Dubbo allows you to build RPC services using a minimal codebase and a lightweight SDK. It supports protocols like:
- Triple (gRPC-compatible)
- Dubbo2 (TCP)
- REST
- Custom protocols
🌱 Microservices with Spring Boot
Kickstart your project using Spring Boot Starter.
Using just a dependency and a YAML config, you can unlock the full power of Dubbo: service discovery, observability, tracing, etc.
