Voiden.md

Voiden.md is an open-source API client that treats API work like code. It uses plain text .void files that live in your Git repository, combining executable requests, documentation, and reusable components in a single file format. Unlike traditional API tools that scatter knowledge across Postman collections, Notion docs, and Slack threads, Voiden keeps everything versioned alongside your code.

• Executable API Docs - Runnable requests, documentation, and human explanations live side-by-side in Markdown and execute in place, eliminating the need to maintain separate documentation.

• LEGO for HTTP - Every part of a request—endpoints, headers, auth, params—is a composable block that you can reuse across files and version control like code. Create an auth block once and reference it everywhere.

• Truly Git-Native - No export, no sync, no JSON blobs. Plain Markdown files where Git is the storage layer. Review API changes in PRs just like code changes.

• Offline-First - No login required, no cloud dependency, no telemetry. Works entirely on your machine without internet connectivity.

• Modular & Reusable - Create blocks for auth, headers, and base URLs. Reference them everywhere. Change once, update everywhere across your entire project.

• Extensible by Design - Blocks and plugins are first-class citizens. Build custom functionality and share what you create with the community.

To get started, download Voiden.md from the website or check out the GitHub repository. Create .void files in your project repository and start building API requests using the block-based syntax. Your API work becomes part of your codebase, versioned and reviewable in pull requests. The tool collapses design, testing, and documentation into one file, one format, and one workflow.
