Kitex [kaɪt'eks] is a **high-performance** and **strong-extensibility** Go RPC framework that helps developers build microservices. If the performance and extensibility are the main concerns when you develop microservices, Kitex can be a good choice.

## Basic Features

- **High Performance**

Kitex integrates [Netpoll](https://github.com/cloudwego/netpoll), a high-performance network library, which offers a significant performance advantage over [go net](https://pkg.go.dev/net).

- **Extensibility**

Kitex provides many interfaces with default implementations for users to customize. You can extend or inject them into Kitex to fulfill your needs (please refer to the framework extension section below).

- **Multi-message Protocol**

Kitex is designed to be extensible to support multiple RPC messaging protocols. The initial release contains support for **Thrift**, **Kitex Protobuf** and **gRPC**, in which Kitex Protobuf is a Kitex custom Protobuf messaging protocol with a protocol format similar to Thrift. Kitex also supports developers extending their own messaging protocols.

- **Multi-transport Protocol**

For service governance, Kitex supports **TTHeader** and **HTTP2**. TTHeader can be used in conjunction with Thrift and Kitex Protobuf.

- **Multi-message Type**

Kitex supports **PingPong**, **One-way**, and **Bidirectional Streaming**. Among them, One-way currently only supports Thrift protocol.

- **Service Governance**

Kitex integrates service governance modules such as service registry, service discovery, load balancing, circuit breaker, rate limiting, retry, monitoring, tracing, logging, diagnosis, etc. Most of these have been provided with default extensions, giving users the option to integrate them as desired.

- **Code Generation**

Kitex has built-in code generation tools that support generating **Thrift**, **Protobuf**, and scaffold code.

## Performance

Performance benchmark can only provide a limited reference. In production, there are many factors that can affect actual performance.

We provide the [kitex-benchmark](https://github.com/cloudwego/kitex-benchmark) project to track and compare the performance of Kitex and other frameworks under different conditions for reference.
