Platform Features

A smarter way
to build your docs.

AI Support

Integrate your own AI out of the box. Give your users conversational search and instant answers right from your docs.

MDX powered

Write docs in MDX — full Markdown plus React components. Import your own components or use Viabl's built-ins.

Docs as Code

One docs.json controls everything — navigation, branding, colors, and search. Version control alongside your codebase.

OpenAPI support

Point to your OpenAPI spec and get a beautiful, interactive API reference automatically generated.

Version switcher

Ship docs for multiple versions of your product. Users switch between them without leaving the page.

VS Code Extension

Write documentation faster with autocomplete for viabl components, props, and frontmatter — right inside VS Code. No more flipping back to the docs to remember component syntax

Built-in SEO

Automatically generated sitemaps, robots.txt, and optimized metadata. Your docs are discoverable by search engines right out of the box.

Deploy Anywhere

Export your documentation as a static site and host it anywhere—Vercel, Netlify, GitHub Pages, AWS, or your own server.
