Voiden

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.
