Turn Markdown into a small, predictable document model.

Parse once, keep the AST serializable, and render matching HTML or React without pulling a content-processing framework into every page.

Why Markdown

Small enough to understand. Specific enough to trust.

A document model you can inspect.

The parser produces a serializable AST instead of hiding content behind an opaque render pipeline.

Safe defaults at the boundary.

Raw HTML and executable URLs are handled deliberately, with malformed input tested as a normal case.

HTML and React stay in agreement.

Render the same syntax profile on the server or in components without maintaining two interpretations.

Docs features are opt-in.

Add callouts, tabs, headings, comments, and framework-aware content through focused extensions.

  1. 01 / Source

    Controlled Markdown for a blog, docs page, or changelog.

  2. 02 / Parse

    A deterministic, serializable tree with stable node shapes.

  3. 03 / Extend

    Only the docs conventions the product actually needs.

  4. 04 / Render

    Matching HTML or React output with safe defaults.

Content pipeline

Every transformation stays visible.

A short pipeline is easier to reason about, easier to test, and easier to run identically during SSR and in the browser.

Built to compose

Bring your own highlighter. Keep the boundary explicit.

TanStack Markdown accepts external syntax highlighting instead of bundling a grammar engine. TanStack Highlight is the small, synchronous companion built for that job.
