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
