Features

The first tool where runnable API requests, block-level structures, and human-written explanations live side-by-side in the same Markdown file—and the editor can execute them in-place. This is the first true "live Markdown + API runner" paradigm.

Every other API tool treats a request as a monolithic object. Voiden is the first to deconstruct requests into composable blocks (endpoint, query, headers, json, auth) that are independently editable, reusable across requests, and version-controlled as text. Function abstraction for API work.

Postman exports JSON blobs. Insomnia exports YAML. Bruno has collections but not docs. Voiden is the first where the native format is Markdown, everything is plain-text blocks, no proprietary collections, no export, no sync integrations. Git is literally the storage layer.

Design lives in OpenAPI. Testing lives in Postman. Docs live in Confluence. Voiden is the first tool where you design a request, test it, capture responses, write documentation above it, and commit—all in the same place. Three categories collapsed into one unified artifact.

No proprietary workspace. No binary exports. No schema lock-in. Pure text all the way down. The first tool to make API knowledge a pure-text asset that's diffable like code, refactorable, greppable, AI-editable, and merge-friendly. Unlocks AI manipulation like code.

Auth blocks reused across files. Environment blocks defining variables. Header blocks toggled on/off. Blocks overridden at request level. The first inheritance-like abstraction for API request building. No other tool has this.

For the first time, you don't have a fixed interface for an API client. Compose it however you want. Your API needs headers? Add headers, nothing else. Needs body + headers? Add just those. Arrange blocks in an order that makes sense for your documentation. The interface adapts to your API, not the other way around.

XML blocks, JSON blocks, text blocks, file attachments, environment variables, multi-body types, raw and structured bodies—all as auto-previewable sections. Other tools handle these as UI toggles. Voiden is the first to treat content types as Markdown block primitives, not UI widgets.

Voiden files open in VS Code, GitHub, your own Electron client, can be parsed by future tools, CI-tested, generated, or linted. The first tool where API requests are portable across editors, repos, platforms, team setups, and future tools. There's no "Voiden workspace"—the repo is the workspace.
