Fuego is a production-ready Go web API framework that automatically generates OpenAPI 3 documentation from typed handler code using generics, built on top of net/http. It also supports HTML templating and can be plugged into existing Gin or Echo servers to add OpenAPI generation.

Use cases

• generate openapi docs from go code
• build rest apis in go with automatic documentation
• add openapi spec to existing gin or echo server
• api framework with validation and error handling
• server-rendered html pages in go with templ
• centralized rfc 9457 error responses in go

When to choose

• you want OpenAPI 3 specs generated from Go handler signatures instead of comments or YAML
• you want a modern net/http-compatible router with generics-based serialization and validation
• you need to retrofit OpenAPI docs onto an existing Gin or Echo API

When to avoid

• you need a framework with a huge middleware ecosystem or non-Go runtimes
• your project targets Go versions older than 1.22
• you prefer spec-first (OpenAPI YAML) workflows rather than code-first
