chi is a lightweight, idiomatic HTTP router for Go that is 100% compatible with net/http and built around the context package. It supports composable middleware, route groups, and sub-router mounting, making it well suited for large REST API services.

Use cases

• build a REST API in Go
• route HTTP requests with middleware in Go
• replace gorilla/mux with a maintained stdlib-compatible router
• structure a large Go microservice with sub-routers
• generate route documentation from Go source
• add request timeouts and logging middleware to Go HTTP services

When to choose

• you want a fast, minimal router with zero external dependencies
• you need full net/http compatibility to reuse ecosystem middleware
• you are building large, maintainable REST APIs in Go

When to avoid

• you need a full web framework with templating, ORM, or validation built in
• you prefer a batteries-included framework like Gin or Echo
• you need GraphQL or gRPC routing rather than REST
