A return-value-based Go web framework for building clean, scalable server-side applications.
Zenqo is a framework for building efficient, maintainable Go web applications. Handlers return (data, error) instead of manually writing to http.ResponseWriter — the framework handles JSON serialization, status codes, and error responses automatically.
Under the hood, Zenqo uses chi as its router, keeping Go's performance while removing the boilerplate that slows you down.
Handlers are pure functions that return (data, error). The framework handles JSON serialization, status codes, and error responses — so your code stays focused on business logic.
// Zenqo
func getUser(r *http.Request) (any, error) {
user, err := svc.FindByID(id)
if err != nil {
return nil, core.ErrNotFound("user not found")
}
return user, nil
}go install github.com/zenqos/zenqo/cmd/zenqo@latest

cd my-app && zenqo dev→ Full guide: Getting Started
- Return-value handlers —
(any, error)signature, automatic JSON & status codes - Controllers — group routes under a base path with
BaseController - Bind & Validate —
Bind[T]decodes JSON,BindQueryStruct[T]binds query params, both run struct validation - Guards & Interceptors — access control and lifecycle hooks at route, controller, or global level
- Error handling — panic recovery, typed errors, RFC 9457 Problem Details, customizable global error handler
- Auto camelCase — struct fields serialize as camelCase without
jsontags - OpenAPI 3.1 — auto-generated spec from route metadata, Swagger UI, security schemes
- Built-in middleware — CORS, rate limiting, secure headers, request ID, CSRF, real IP
- File uploads —
BindFile/BindFileswith size limits and content-type detection - CLI —
zenqo new,zenqo generate,zenqo devwith optional--watchhot reload
examples/basic— Direct routing without controllersexamples/crud— Full CRUD API with Controller + Service patternexamples/auth— JWT authentication with Guards, Interceptors, and Bind+Validation
