Voiden

Offline, Git-native API workspace built on Markdown files

About Voiden

Voiden is an API workspace that stores requests, documentation and tests together in plain Markdown .void files committed to Git alongside the code. Requests are composed from reusable blocks, everything runs offline with no account or cloud backend, the same files execute headlessly in CI, and requests can be exposed as MCP tools for AI agents.
