When your users need Word — not “Word-like” or “compatible” with — but actual DOCX documents with all their complexity, that is what we do. SuperDoc brings Microsoft Word to the web.

​
What We Built

We built a modern JS library for rendering and editing Word documents—complete with comments/tracked changes, complex tables, advanced pagination/headers, realtime collaboration, and and every Word feature users actually use. It was intention-built for advanced documents (e.g., legal contracts) and advanced document workflows and AI integrations.

​
What Makes This Work

  • Real DOCX formatting, not rich text: This isn’t another contenteditable wrapper. SuperDoc handles actual .docx files with their full complexity.
  • Seamless integration: Can be added to React, Vue, vanilla JS, or any modern framework. One API, zero lock-in.
  • Frontend and backend: SuperDoc fully runs in the browser or in server-side Node, great for workflow automations and AI uses.
  • Highly extensible: Completely customize the UX and add in your own features, plugins, commands, and nodes.
  • Dual licensed: Available under AGPLv3 for community use and a Commercial License for enterprise deployments.
