Markdown Syntax

Ferromark parses CommonMark and GFM. Choose the syntax your authors need in Rust or Node.js, then choose an independent HTML trust policy.

Everyday Markdown and GFM

CommonMark covers headings, paragraphs, lists, links, emphasis, images, and code. GFM adds pipe tables, task lists, strikethrough, and autolinks. Ferromark checks its output against the CommonMark and GFM examples.

Publishing syntax

Ferromark Flavored Markdown (FFM) collects the opt-in syntax for captions, attributed quotes, styled tables, inline spans, notes, and other publishing needs. Its guide shows authored examples, the options that recognize them, and links to the detailed rules. Enable only the extensions your content uses; there is no single FFM switch.

The feature comparison lists capabilities across engines. MDX boundaries and optional typography have their own guides.
