The API Knowledge Problem

Your API work lives in 5 places:

  • ✕Postman/Insomnia (the requests)
  • ✕Notion/Confluence (the docs)
  • ✕Slack/Jira (the context)
  • ✕README files (the examples)
  • ✕Git (the code... but not the API stuff)

Every time something changes:

  • →Update Postman
  • →Update docs
  • →Tell your team
  • →Hope nobody uses the old version

What's the source of truth? Nobody knows.

Voiden fixes this.

Everything in .void files. Versioned in Git. One source of truth.

A New Category

API Work,
Treated Like Code.

File-centric. Text-based. Git-native. Built for developers who version control everything else—why not API requests?

Executable API Docs

The first tool where runnable requests, documentation, and human explanations live side-by-side in Markdown—and execute in-place.

LEGO for HTTP

Every part of a request—endpoints, headers, auth, params—is a composable block. Reuse across files. Version control like code.

Truly Git-Native

No export. No sync. No JSON blobs. Plain Markdown files. Git is the storage layer. The first truly git-native API client.

Design + Test + Document

The first tool to collapse design, testing, and documentation into one file, one format, one workflow. All in the same place.

Built Different

Most API tools are workspace-centric—collections in the cloud, GUI-first, export/import to sync with Git.

Voiden is file-centric. Plain text. Git is the workspace. It looks unfamiliar because the architecture is fundamentally different.

Real Talk

"Tired of Platforms That Think They Know Better Than You?"

Most API tools assume they should run your workflow. Voiden doesn't. It gives you structure, flexibility, and a workspace you actually control.
