ProseMirror

Summary

ProseMirror is a toolkit for developers building rich-text editors on the web. It supports structured documents through a WYSIWYG-style interface, while allowing applications to define the content and document shape. Rather than treating a document as an HTML blob, it gives application code control over its own document data structure. Schemas and plugins let developers customize that structure and extend the editor. Four core modules handle the document model, editor state, view and transformations; additional modules offer commands, key bindings, undo history, input macros and collaboration. Multiple people can edit together in real time. The project’s examples include Markdown editing, image uploads, custom schemas, menus, code editors, footnotes and track changes. ProseMirror is open source and legally free for commercial use. It is installed with npm and can be self-hosted. It is not a ready-made editor component: implementation is modular and generally involves a bundler. The project directs questions to its forum and bug reports to its issue tracker; its GitHub repository says development has moved to Forgejo.

Who it is for

ProseMirror is for developers who need to build a custom web editor for structured content. It may suit teams that want control over document schemas and real-time collaboration, rather than a drop-in editor component.
