Capabilities

No magic. Just Go.

Everything you need to build production-ready Web APIs.

Radix Tree Router

Per-method radix tree with zero-allocation path params, backtracking, and 405 detection.

Request Binding

Bind JSON, XML, form data, headers, query strings, and path params to typed Go structs.

Middleware

Global, per-route, and group-scoped middleware. Built-in CORS, CSRF, rate-limit, and more.

Validation

Pluggable validator backed by go-playground/validator with optional auto-validation after bind.

OpenAPI

Auto-generated OpenAPI 3.0.3 spec with Swagger UI. Zero cost when unused.

Auth

JWT, Basic, API Key, OAuth2, OIDC — with RBAC and PBAC. Separate package.

Context

Per-request context with typed values, deadline control, and automatic cleanup.

Route Groups

Organize routes with shared prefixes, middleware, and metadata for cleaner APIs.

See it in action

Zero-alloc routing. Plain handlers.

A radix tree router with path params, JSON responses, and middleware — in under 20 lines. No boilerplate, no framework directives.
