Hey Product Hunt! I'm Paranjay, a 23-year-old developer from India, and I built SwagDoc to solve a problem I constantly faced: generating API documentation without changing code. SwagDoc acts as a proxy to capture your API traffic, automatically inferring endpoints, data types, and schemas to generate OpenAPI/Swagger docs. No code changes needed - just point it at your API and let it observe! Perfect for legacy systems, rapid prototyping, or when you need docs but lack time. It works with any API technology and comes with pre-built binaries for all platforms. I'd love your feedback, feature suggestions, or questions about the implementation. Try it out and let me know what you think!
