Zudoku is an open-source documentation framework built for API references. It converts OpenAPI v2/v3 schemas into a static, SEO-friendly documentation site with an interactive playground for testing endpoints, built-in search, and support for OAuth2 and JWT authentication flows. Teams can extend it with MDX pages and a component library, then self-host it or deploy it through Zuplo, the API gateway company that maintains the project. The framework itself is free and open source; hosting and gateway features are a separate, optional purchase from Zuplo.

Pros & cons of Zudoku
Zudoku is a solid pick if you already have an OpenAPI schema and want a documentation site without paying for a hosted docs platform, since the framework itself costs nothing and can be self-hosted. The tradeoff is that you're running your own build and deploy pipeline unless you opt into Zuplo's paid hosting, and it leans on OpenAPI as the source of truth rather than freeform writing.
Pros
- Converts OpenAPI v2/v3 schemas straight into a working documentation site with a live testing playground
- Free and open source, with no seat or usage fees for the framework itself
- Supports OAuth2/JWT auth flows and MDX for custom written pages alongside generated API reference
Cons
- Self-hosting requires running your own build and deploy process unless you pay Zuplo for hosting
- Best suited to API-first documentation rather than general product docs or tutorials
- Backed by a single company, so its roadmap is tied to their commercial priorities
Best for
- Teams with an existing OpenAPI or Swagger schema who want a free documentation site
- Developers comfortable self-hosting a static site build
- Projects that want an interactive API playground built in rather than bolted on
Not for
- Teams without an OpenAPI schema who want to write docs freeform first
- Non-technical writers who need a hosted WYSIWYG editor
Watch out: It is a framework you deploy, not a hosted product by default — budget engineering time for the initial setup.
