About Voiden
Voiden is an offline, Git native API workspace built with Electron, TypeScript, and JavaScript. It lets developers, QA engineers, and technical writers design, test, document, and collaborate on APIs using plain text .void files. The project lives in the API development and testing ecosystem, and its topics describe it as an alternative to Bruno and Insomnia. It supports REST, GraphQL, gRPC, and WebSockets through plugins, and it imports collections from Postman, Insomnia, and Swagger or OpenAPI.
