Voiden.md logo Voiden.md

Voiden.md is an offline-first, Git-native API workspace that unifies specs, docs, tests, and mocks using programmable Markdown blocks. Build APIs the way you actually work.

Restfox.dev logo Restfox.dev

Browser based HTTP client inspired by Insomnia and Postman
Not present

Voiden is an offline, Git-native API client built around plain text files. Instead of storing requests in cloud workspaces or JSON collections, Voiden runs HTTP requests directly from Markdown files in your repository.

Requests, documentation, and tests live side-by-side in the same file and execute in place. Every part of a request โ€” endpoints, headers, auth, params โ€” can be structured and reused, making API work modular and version-controlled like code.

There are no exports, no sync steps, and no hidden storage layer. Git is the workspace. Markdown is the format. Your API requests are just files in your repo.

Voiden is designed for developers who already version control everything else โ€” and expect their API tooling to work the same way.

  • Why Open Source API Tools Are Having a Moment
    I've personally enjoyed following projects like Voiden. It's been interesting to see how quickly the project has evolved and how much the community has contributed. Recently they've even added support for AI agents like Claude and Codex through skills, which feels like a glimpse of where developer tools are heading next. - Source: dev.to / about 2 months ago
  • Slumber a TUI HTTP Client
    Great to see this space so active.I see this a TUI. You can also try out Voiden : https://voiden.md/ which has a different approach to this. Also YAML is a interesting choice - any reasons for this. - Source: Hacker News / 3 months ago
  • A Markdown-based test suite
    I think you will like https://voiden.md/ - some what similar to what you did here. - Source: Hacker News / 3 months ago
  • Show HN: Files.md โ€“ open-source alternative to Obsidian
    I too built something similar but as an API Client - https://voiden.md/ - Obsidian really picking up ! - Source: Hacker News / 3 months ago
  • Show HN: Mezz, a curl-able WiFi sandbox for IoT pentesting
    This is very interesting - instead of curl you can integrate https://voiden.md/ maybe. - Source: Hacker News / 3 months ago
