Sourcey

Docs straight from the source.

Sourcey turns OpenAPI, MCP, Doxygen XML, godoc, rustdoc, and Markdown into one static HTML site you own: reference, guides, changelog, roadmap, and llms.txt from the same build, deployable anywhere.

Everything renders at build time: no dashboard, no runtime, no API calls to render your own documentation.

Features

• OpenAPI 2.0, 3.0, 3.1, and 3.2: full spec coverage including QUERY operations, response summaries, hierarchical tags, deviceAuthorization OAuth, querystring parameters, and $self-aware refs for multi-document APIs
• API reference from OpenAPI: endpoints, parameters, request/response schemas, and auto-generated code samples across 10 supported languages. The default set is cURL, JavaScript, and Python; configure TypeScript, Go, Ruby, Java, PHP, Rust, and C# when you want them
• MCP server documentation: tools, resources, prompts rendered as browsable reference with JSON-RPC, TypeScript, and Python code samples. Color-coded method types, annotation badges, connection config cards
• Rich guides: markdown pages with steps, cards, accordions, syntax-highlighted code blocks, and prose alongside your API reference
• One-time migration: convert an existing Astro, MkDocs, Docusaurus or Mintlify documentation project to native Sourcey Markdown and configuration, with a dry-run diff and checks for routes, fragments, content and media. Migration guide
• Product story pages: changelog, roadmap pages, examples, reference material, search, and portable context exports in one source-owned site
• C++ and Doxygen: feed Doxygen XML output, get modern searchable API docs with exact member search, source links, templates, qualifiers, examples, inherited members, and relationship sections. No new parser, no four-tool Breathe/Exhale/Sphinx pipeline
• Go and godoc: native package documentation extracted from Go source via the toolchain. Render Go modules as Sourcey tabs, generate standalone static Go docs sites, or commit godoc.json snapshots for JS-only docs hosts. No Doxygen detour
• Rust and rustdoc: native API documentation from nightly rustdoc JSON, with doctests as a first-class extracted view. URL-encoded parametric impl anchors for deep-link parity with doc.rust-lang.org. Snapshot mode lets CI build on stable Rust toolchains. Aggregated doctests index across the workspace
• Readable reference for agents: Markdown for pages, API operations and schemas, plus documents.json, llms.txt and llms-full.txt. Code examples retain their formatting
• API and agent discovery: opt into public OpenAPI bundles, ARD manifests and RFC 9727 API catalogs. Mounted docs keep the host's root manifest under its owner's control. Configuration
• Docs over MCP: the optional sourcey-docs-mcp package searches and reads a built documentation directory. Its SDK stays out of the generator and browser bundle
• TypeScript config: sourcey.config.ts with defineConfig() autocomplete; theme, navbar, CTA buttons, footer
• Themes: default (sidebar + TOC), minimal (single column), api-first (full width, with examples beside each API operation), and reader (editorial specification); colors, fonts, layout dimensions, and custom CSS on top
• Vite dev server: SSR hot reload on every component and CSS change; spec and markdown changes trigger instant refresh
• Light and dark: semantic design tokens, light and dark logo variants, the reader's choice saved and applied before the page draws
• Search in the browser: full-text and typo-tolerant across every page, operation and symbol, loaded in shards as it is needed; Cmd+K
• Static HTML output: no framework runtime, no vendor lock-in. Deploy to GitHub Pages, Vercel, Netlify, S3, anywhere
• Open source: AGPL-3.0. Self-host, fork, extend. Your docs, your infrastructure

Install

Sourcey CLI

The full Sourcey binary handles OpenAPI, MCP, Doxygen, godoc, rustdoc, and Markdown sources. Existing Astro, MkDocs, Docusaurus and Mintlify projects have one-time converters.

Then sourcey init to scaffold a new project, or sourcey build against an existing one. See docs/install.md for full Docker invocations (init / dev / build), the --host flag for containerized dev, Linuxbrew notes, and Nix profile install.

Standalone Go docs generator

imageGo Reference imageGo Report Card

For Go-only consumers without a JavaScript toolchain, sourcey-godoc ships as a separate native binary. It produces static Go docs sites or portable godoc.json snapshots.

Rust snapshot converter

imagecrates.io imagedocs.rs

The rustdoc() adapter consumes nightly rustdoc JSON through the sourcey companion crate and its sourcey-rustdoc converter, so CI can build Rust API docs from a committed snapshot on a stable toolchain. See docs/adapters/rustdoc.md.

Quick start

# Scaffold a project (detects OpenAPI specs and Doxyfiles)
npx sourcey init

# Dev server with hot reload
sourcey dev

# Build static HTML to dist/
sourcey build

# Quick build from a single OpenAPI spec
sourcey build api.yaml -o dist/

In CI, install the project's dependencies and run npx sourcey build; see deploying for GitHub Pages, Netlify, Vercel and Cloudflare Pages.

Astro integration

Astro sites can mount Sourcey directly instead of running a separate docs CI job. The integration reads the same sourcey.config.ts, derives Sourcey's public siteUrl and baseUrl from Astro's site/base plus routeBase, serves docs in Astro dev, and writes docs into Astro's final build output.

// astro.config.ts
import { defineConfig } from "astro/config";
import sourcey from "sourcey/astro";

export default defineConfig({
  site: "https://sourcey.com",
  integrations: [
    sourcey({
      config: "./sourcey.config.ts",
      routeBase: "/docs",
    }),
  ],
});

You can also share an imported config object when you want one config module to feed both the CLI and Astro:

import { defineConfig } from "astro/config";
import sourcey from "sourcey/astro";
import docs from "./sourcey.config";

export default defineConfig({
  site: "https://sourcey.com",
  integrations: [sourcey({ config: docs, configDir: ".", routeBase: "/docs" })],
});

To give the mount root to an Astro page of your own, such as a product page at /docs above the documentation, set landingPage: false. Sourcey leaves an automatic root copy out of the build and lets Astro serve its own landing page. An authored index.md is still a real documentation route; give it a separate slug when the host owns that address.

Configuration

Create sourcey.config.ts in your project root:

import { defineConfig, openapi } from "sourcey";

export default defineConfig({
  name: "My API",
  navigation: {
    tabs: [{ tab: "API Reference", source: openapi("./openapi.yaml") }],
  },
});

Each tab has one source, usually created with markdown(), openapi(), mcp(), doxygen(), godoc(), or rustdoc(). Pages are referenced by slug (e.g. "quickstart" resolves to quickstart.md). See configuration for the site's settings, navigation for tabs, groups and pages, and themes for colours, fonts and layout.

Go documentation (godoc)

Render Go package docs as a tab inside your Sourcey site, branded and styled with the rest of your documentation. Native toolchain extraction (go list + go/parser + go/doc) feeds the same renderer as your OpenAPI, MCP, and Markdown tabs, so signatures, examples from *_test.go, and source links sit alongside your guides instead of bouncing readers to pkg.go.dev.

Live: scafld's Go API reference →

{ tab: "Go API", source: godoc(".") }

The shorthand expands to { module: ".", packages: ["./..."], mode: "auto", includeTests: true }. Live mode uses the host Go toolchain; snapshot mode reads a committed godoc.json and needs no Go on the build host. See the Go guide for packages, mode, goEnv, sourceBasePath, and includeUnexported.

Markdown components

Guides support rich components in standard markdown:

<Steps>
  <Step title="Install">Run `npm install sourcey`</Step>
  <Step title="Configure">Create `sourcey.config.ts`</Step>
  <Step title="Build">Run `sourcey build`</Step>

</CardGroup>

<AccordionGroup>
  <Accordion title="How does auth work?">We use API keys and OAuth2.</Accordion>
</AccordionGroup>

Theme

All visual configuration lives under theme. theme.name selects the complete renderer; colors, fonts, layout dimensions, and custom CSS apply on top:

theme: {
  name: "api-first",
  colors: { primary: "#f59e0b", light: "#fbbf24", dark: "#d97706" },
  fonts: { sans: "Lexend", mono: "Fira Code" },
  layout: { sidebar: "16rem", content: "48rem" },
  css: ["./brand.css"],
}

Themes control the complete layout structure: "default" (sidebar + TOC), "minimal" (single centered column), "api-first" (full width, with each API and MCP operation's examples beside it), and "reader" (editorial specification reader). Shared brand settings apply on top; a named font loads from Google Fonts. Theme-specific options are only interpreted by the selected theme. See themes.

CLI

sourcey init                      Start a project (detects OpenAPI specs and Doxyfiles)
sourcey dev                       Dev server (reads sourcey.config.ts)
sourcey build                     Build site (reads sourcey.config.ts)
sourcey build api.yaml            Quick build from a single spec
sourcey check                     Check sources, routes and links without writing
sourcey validate api.yaml         Validate a spec file
sourcey migrate mkdocs            Convert an Astro, MkDocs, Docusaurus or Mintlify project
sourcey godoc --out godoc.json    Snapshot a Go module's docs to JSON

Run sourcey <command> --help for flags, or see the CLI reference.

Agent skill

The Sourcey skill teaches a coding agent to start a documentation site, migrate one from Docusaurus, MkDocs, Mintlify or Astro, shape its API and MCP references, and review it as a reader before it ships. It is in the npm package at node_modules/sourcey/skills/sourcey, and this repository packages it as the sourcey-docs plugin for each agent host:

# Claude Code
/plugin marketplace add sourcey/sourcey
/plugin install sourcey-docs@sourcey

# Gemini CLI
gemini extensions install https://github.com/sourcey/sourcey

Cursor, Grok Build and ChatGPT/Codex read the manifests in .cursor-plugin/, .grok-plugin/ and plugin.json. Sourcey's startup offers have their own plugin, sourcey; this one is for the documentation generator.

Development

git clone https://github.com/sourcey/sourcey.git
