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
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.

Path	Command	Requires
npm	`npm install -g sourcey`	Node 20+
Homebrew	`brew tap sourcey/tap && brew install sourcey`	macOS / Linuxbrew
Docker	`docker run -v "$PWD":/docs sourcey/sourcey`	Docker
Nix	`nix run github:sourcey/sourcey`	Nix (flakes)

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.

Path	Command
Go	`go install github.com/sourcey/sourcey/go/sourcey-godoc/cmd/sourcey-godoc@latest`
Homebrew	`brew install sourcey/tap/sourcey-godoc`
Scoop	`scoop bucket add sourcey https://github.com/sourcey/scoop-bucket && scoop install sourcey-godoc`

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.

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" })],
});

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.
