## What it is
Huma is a modern micro-framework for building HTTP REST/RPC APIs in Go, backed by OpenAPI 3.1 and JSON Schema. It is router-agnostic (bring your own router), generates always-up-to-date OpenAPI specs and interactive docs from code, and includes declarative validation, RFC 9457 errors, and a built-in service CLI.

## Use cases
- build a REST API in Go with automatic OpenAPI 3.1 documentation
- add OpenAPI docs to an existing Go service without rewriting routes
- generate always up-to-date API specs from Go code
- use chi, gin, echo, fiber, or gorilla/mux with a declarative API layer
- serve interactive API docs like Stoplight Elements or Swagger UI
- add request validation and RFC 9457 JSON errors to a Go HTTP API
- wrap a Go service with a CLI for flags, env vars, and graceful shutdown

## When to choose
- you want code-first OpenAPI 3.1 generation that can't drift from your implementation
- you need incremental adoption on top of an existing Go router and middleware
- you want static typing, automatic input validation, and guard rails for your API handlers
- you need generated developer tooling and interactive docs out of the box

## When to avoid
- you need a design-first workflow where the spec is authored before code
- you want a batteries-included framework with its own router, ORM, and auth
- you're building non-HTTP services or non-REST protocols
- your project must run on Go versions older than the required minimum
