Ferromark turns Markdown into HTML for Rust and Node.js pipelines, while exposing metadata, rendering policies, and publishing-oriented features.

Landing page captured for the 2026-09-19 issue.

For: Rust and Node.js publishing-tool builders
Worth noticing: The site reports agreement with all 652 CommonMark specification examples and comparisons with cmark and cmark-gfm.

Field notes

Ferromark exposes both a Rust crate and a native engine behind a typed JavaScript API, with command-line use also documented. Its publishing-oriented surface includes front matter extraction, heading-derived navigation, document-tree inspection, rendering hooks, and configurable trust policies. The homepage lists version 2.0.0-rc.2 as a breaking upgrade from v1 and links to migration guidance, syntax references, and measured-workload documentation.
