Voiden – an offline, Git-native API tool built around Markdown
Hi HN, We have open-sourced Voiden. Most API tools are built like platforms. They are heavy because they optimize for accounts, sync, and abstraction - not for simple, local API work. Voiden treats API tooling as files. It’s an offline-first, Git-native API tool built on Markdown, where specs, tests, and docs live together as executable Markdown in your repo. Git is the source of truth. No cloud. No syncing. No accounts. No telemetry.Just Markdown, Git, hotkeys, and your damn specs. Voiden is extensible via plugins (including gRPC and WSS). Repo:…
In plain words
Voiden is an offline-first API tool that uses Markdown files stored in Git repositories to write and execute API specifications, tests, and documentation. Designed for developers who want local API work without cloud accounts or syncing, it operates entirely as files within version control. The tool supports extensions for protocols like gRPC and WebSockets and relies on Git as its single source of truth, offering a lightweight alternative to platform-based API tools.
