用于构建微服务的高性能、强扩展的 Go HTTP 框架。
English | 中文
Hertz [həːts] is a high-usability, high-performance and high-extensibility Golang HTTP framework that helps developers build microservices. It was originally a fork of fasthttp and inspired by gin, echo and combined with the internal requirements in ByteDance. At present, it has been widely used inside ByteDance. Nowadays, more and more microservices use Golang. If you have requirements for microservice performance and hope that the framework can fully meet the internal customizable requirements, Hertz will be a good choice.
High usability
During the development process, it is often more important to write the correct code quickly. Therefore, in the iterative process of Hertz, we actively listen to users' opinions and continue to polish the framework, hoping to provide users with a better user experience and help users write correct code faster.
High performance
Hertz uses the self-developed high-performance network library Netpoll by default. In some special scenarios, compared to Go Net, Hertz has certain advantages in QPS and time delay. For performance data, please refer to the Echo data in the figure below.

Comparison of three frameworks:
For detailed performance data, please refer to hertz-benchmark.
High extensibility
Hertz adopts a layered design, providing more interfaces and default extension implementations. Users can also extend by themselves. At the same time, thanks to the layered design of the framework, the extensibility of the framework will be much greater. At present, only stable capabilities are open-sourced to the community. More planning refers to RoadMap.
Multi-protocol support
The Hertz framework provides HTTP/1.1 and ALPN protocol support natively. In addition, due to the layered design, Hertz even supports custom build protocol resolution logic to meet any needs of protocol layer extensions.
Network layer switching capability
Hertz implements the function to switch between Netpoll and Go Net on demand. Users can choose the appropriate network library for different scenarios. And Hertz also supports the extension of network library in the form of plug-ins.

Performance testing can only provide a relative reference. In production, there are many factors that can affect actual performance. We provide the hertz-benchmark project to track and compare the performance of Hertz and other frameworks in different situations for reference.
Hertz-contrib is a partial extension library of Hertz, which users can integrate into Hertz through options according to their needs, built and maintained by the community.
