Desktopfree

APISpec is a command-line tool and browser UI that generates OpenAPI 3.1 specifications directly from Go source code. It analyzes routes, call graphs, and type definitions across common frameworks like Gin, Echo, Chi, and Fiber, so documentation stays accurate without hand-written annotations. It's built for Go developers who maintain REST APIs and want their API docs to track the real implementation.
