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 publishes 1 API on the APIs.io network. Tagged areas include API Design, API Testing, API Documentation, Developer Tools, and Git-Native.

The Voiden catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Voiden’s developer surface includes engineering blog and 9 more developer resources.
