  Voiden is an offline-first, Git-native API workspace that unifies API design,
  testing, and documentation in plain Markdown .void files stored alongside
  your codebase. It uses composable, reusable blocks (endpoints, auth, headers,
  params, bodies) that behave like code — inheritable, versionable, and
  composable — eliminating copy-paste drift across API definitions. Supports
  REST, GraphQL, WebSocket, and gRPC. Built on Electron (TypeScript), Apache 2.0 licensed.

      Voiden is a desktop application (Electron/TypeScript) for API design,
      testing, and documentation using .void file format — plain Markdown with
      structured request blocks. Features reusable blocks with inheritance and
      composition, Git-native versioning, batch request execution with
      assertions, OpenAPI and Postman import, pre/post-request scripting
      (JavaScript, Python, shell), and offline-first operation. No public REST API.
