Openapi Swagger Documentation Generation From Database Schema

via “openapi/swagger specification generation”

Design-first Go framework that generates API code, documentation, and clients. Define once in an elegant DSL, deploy as HTTP and gRPC services with zero drift between code and docs.

Unique: Generates OpenAPI specs directly from the internal expression tree rather than parsing generated code or annotations, ensuring 100% fidelity between design and spec; validation constraints from the DSL are automatically mapped to OpenAPI schema constraints (minLength, maxLength, enum, pattern, etc.)

vs others: More accurate than annotation-based OpenAPI generation (like Swag for Go) because the spec is generated from the design model before code generation, not reverse-engineered from code; more maintainable than hand-written specs because regeneration keeps specs synchronized with design changes
