Hertz is a high-performance, extensible Go HTTP framework from CloudWeGo (ByteDance) for building microservices. It uses the Netpoll network library by default, supports HTTP/1.1, HTTP/2, ALPN and WebSocket, and offers a layered design with extensive extension points and an hz code generation tool.
Use cases
- build high-performance microservices in go
- serve http apis with low latency and high qps
- replace gin or echo with a faster go http framework
- generate go http service scaffolding from idl
- build websocket and http/2 services in go
- customize framework layers like transport or protocol
When to choose
- you need maximum http throughput and low latency in go
- you are building microservices within the cloudwego ecosystem (kitex, netpoll)
- you need a layered, highly extensible http framework
- you want built-in code generation from thrift or protobuf idl
When to avoid
- you need a minimal framework with the largest plugin ecosystem (gin, echo)
- you are not writing go
- your service is simple and performance is not a concern
- you rely on net/http middleware compatibility without adapters
