Voiden.md is an offline-first, Git-native API workspace that unifies API specs, documentation, tests, and mocks using programmable Markdown blocks. Built for developers who treat API work like code.

Key Features

  • Git-Native Workflow: Store API specs, tests, and docs in .void files committed directly to your Git repository
  • Executable Markdown: Combine requests, documentation, and context in a single plain-text file that executes in place
  • Reusable Blocks: Decompose API requests into composable components (endpoints, headers, auth, params) for reuse across files
  • Offline-First: Works entirely locally with no cloud dependency, no accounts, and no telemetry
  • CI/CD Integration: Run API tests headlessly in pipelines using @voiden/runner with deterministic exit codes
  • No Vendor Lock-in: Pure Markdown format with Git as the storage layer, ensuring full portability
  • Cross-Platform: Available as a desktop app with plugins and a CLI runner for terminal environments
  • Developer-Friendly: Built by developers for developers who value version control, privacy, and ownership

Tech / Self-Hosting

Voiden.md is open-source software that runs entirely on your local machine. The desktop application is available for Windows, macOS, and Linux, while the @voiden/runner CLI can be deployed in any Node.js environment including CI/CD pipelines. No server infrastructure is required as all data remains local to your device.
