Features

Everything you need for self-hosted docs.

OpenAPI, Doxygen, godoc, MCP, Markdown. Search, themes, and llms.txt in one tool.

Generate from anything

One site from every spec format you use. Point sourcey at what you have and it renders the reference.

  • OpenAPI 2.0 through 3.2

    Full spec coverage including 3.2's `QUERY` operations, hierarchical tags, and response summaries. Endpoints, schemas, and auto-generated code samples in cURL, JavaScript, Python, Go, Ruby, Rust, and more.

  • MCP server docs

    Tools, resources, and prompts rendered as browsable reference. JSON-RPC, TypeScript, and Python code samples.

  • C++ and Java via Doxygen

    Feed in Doxygen XML output and get modern, searchable API docs. Works with Moxygen for Markdown-based rendering.

  • Go via godoc

    Extract Go package docs natively from your source via the Go toolchain. No Doxygen detour. Live mode at build time, or commit a portable godoc.json snapshot.

  • Markdown guides

    Steps, cards, accordions, tabbed code blocks. Rich components in standard markdown alongside your API reference.

Built for developers

The toolchain feels like the rest of your stack. TypeScript, Vite, instant feedback.

  • TypeScript config

    sourcey.config.ts with defineConfig(). Full autocomplete, type checking. One file defines your entire docs site.

  • Vite dev server

    SSR hot reload on every component and CSS change. Spec and markdown changes trigger instant refresh.

  • Instant search

    Client-side fuzzy search across all pages and API operations. Cmd+K to find anything. Works offline.

Ship with confidence

Control how it looks and where it goes. Three theme presets, design tokens, static HTML output, your deploy target.

  • Static HTML output

    Zero framework runtime shipped. No vendor lock-in. Deploy to GitHub Pages, Vercel, S3, anywhere.

  • Three theme presets

    Default sidebar + TOC. Minimal single column. API-first three-column like Stripe. Colors, fonts, and custom CSS on top.

  • Dark mode

    Semantic design tokens, light/dark logo variants, localStorage persistence. Looks great either way.

  • llms.txt generation

    Auto-generate llms.txt and llms-full.txt alongside your HTML. Your docs serve developers and AI agents from one build.

Built in

Built in, not bolted on.

Every feature ships with every build. Nothing to install, nothing to configure.

Looks great either way.

Semantic design tokens, light and dark logo variants, localStorage persistence. Every component designed for both modes.

100/100 across the board.

Zero JavaScript runtime means nothing to download, parse, or execute. Every page is semantic HTML with one CSS file. Performance, accessibility, best practices, and SEO — all green.
