A good choice depends on what you mean by “API spec,” but the most common tools are:
-
OpenAPI/Swagger specs
- Swagger Codegen or OpenAPI Generator for generating client/server code and sample models
- Swagger UI or Redoc for interactive documentation
-
Protobuf / gRPC specs
- protoc with language-specific plugins for code generation
- grpc-gateway or grpc-web if you want HTTP/REST docs or browser support
-
GraphQL schemas
- GraphQL Code Generator for client types/hooks and sample operations
- Apollo Studio or GraphiQL for documentation/exploration
If your goal is both docs and code samples from a REST API spec, the usual recommendation is:
- OpenAPI Generator for code samples and SDKs
- Redoc or Swagger UI for human-friendly docs
If you want, I can recommend a specific toolchain based on:
- your spec format,
- target language,
- and whether you need SDKs, docs, or both.
