Summary: Marijn Haverbeke, author of ProseMirror and CodeMirror, published Wordgard, an open-source (MIT) in-browser rich-text editor library. It models documents as schema-based semantic structure with custom elements rather than free-form HTML, supports tables, nested lists, captioned figures, collaborative editing, accessibility, and right-to-left text, and exposes a programming interface for building customized editors. Commercial users are asked to help fund maintenance under a social, non-legal expectation.
Why it matters: A new editor foundation from the ProseMirror author is a candidate base layer for teams building structured document tooling, where schema-first content models reduce the HTML-sanitization surface.
Follow-up: Track a tagged release, versioning stability of the programming interface, and migration notes for ProseMirror users.
