Huma
A modern, simple, fast & flexible micro framework for building HTTP REST/RPC APIs in Go backed by OpenAPI 3 and JSON Schema.
What is Huma?
Huma is a micro framework for building HTTP REST and RPC APIs in Go. It provides a declarative interface on top of your router of choice, automatically generating OpenAPI 3.1 documentation and JSON Schema from your Go types to ensure documentation never gets out of sync with your implementation.
Go developers building modern HTTP REST or RPC APIs who need automatic OpenAPI generation, input validation, and incremental adoption with existing routers and middleware.
Developers choose Huma for its automatic, always-in-sync OpenAPI and JSON Schema generation, its flexibility to work with existing routers like Chi or the standard library, and its guard rails to prevent common API development mistakes.
