Voiden

aid: voiden
name: Voiden
description: 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.
