GitHub - sourcey/sourcey: Precision documentation from OpenAPI, MCP, Doxygen, and Markdown guides. Static HTML you own.

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, auto-generated code samples in 10 languages (cURL, JavaScript, TypeScript, Python, Go, Ruby, Java, PHP, Rust, C#)
• 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
• MkDocs source import: point a tab at mkdocs.yml; Sourcey reads docs_dir and nav so existing MkDocs markdown sites can render without hand-copying the sidebar structure
• 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
• Context exports: auto-generate llms.txt and llms-full.txt alongside your HTML as alternate views of the same documentation graph
• TypeScript config: sourcey.config.ts with defineConfig() autocomplete; theme, navbar, CTA buttons, footer
• Theme presets: default (sidebar + TOC), minimal (single column), api-first (Stripe-style three column); 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
• Dark mode: semantic design tokens, light/dark logo variants, localStorage persistence
• Client-side search: instant fuzzy search across all pages and API operations; 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, MkDocs, and Markdown sources.

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

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

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, the sourcey/build-docs GitHub Action runs the build and deploys to GitHub Pages; see deploying.

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(), mkdocs(), openapi(), mcp(), doxygen(), godoc(), or rustdoc(). Pages are referenced by slug (e.g. "quickstart" resolves to quickstart.md). See docs/configuration.md for theme, navbar, footer, logo, and full tab options.

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 docs/configuration.md 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>
</Steps>

<CardGroup cols={2}>
  <Card title="API Reference" icon="book" href="/api">Full endpoint docs</Card>
  <Card title="Guides" icon="map" href="/docs">Step-by-step tutorials</Card>
</CardGroup>

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

Theme

All visual configuration lives under theme. Colors, fonts, layout dimensions, and a preset that controls page structure:

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

Presets control layout structure: "default" (sidebar + TOC), "minimal" (single centered column), "api-first" (three-column with persistent code panels). Everything else applies on top.
