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 14 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/voiden: open an issue to ask a question, or submit a pull request to add artifacts.
