Widdershins is a Node‑JS tool that converts API specifications written in OpenAPI (2 / 3), Swagger, AsyncAPI or Semoasa into Markdown formatted for static documentation generators such as Slate, ReSlate, Shins or directly to HTML/ReSpec. It’s aimed at API developers and technical writers who need to turn machine‑readable API definitions into clean, searchable, code‑sample‑rich documentation with customizable templates and language tabs.
