Why Explainer?

Built for developers who care about their users' experience.

Ship docs in minutes, not days

Your brand, your way

Tailwind CSS design tokens let you match your documentation to your product identity with a few CSS variable changes.

Extensible by design

Drop in React, Vue, or Svelte components directly in your Markdown. Build interactive examples, live demos, and API playgrounds.

Built for growth

From a single getting-started guide to hundreds of pages — the architecture scales with your project. Multi-collection docs, versioning-ready structure, and automatic navigation.
