Your users need Word. Not “Word-like” or “compatible” with — actual DOCX files with all their complexity. SuperDoc brings Microsoft Word to the web.

​
What We Built

A DOCX editor that handles real Microsoft Word documents on the web—complete with tracked changes, complex tables, and every Word feature your users actually use. Built specifically for contract management, proposals, and document automation workflows where Word compatibility isn’t optional.

​
What Makes This Work

  • Real DOCX, not rich-text: This isn’t another contenteditable wrapper. SuperDoc handles actual .docx files with their full complexity.
  • Framework agnostic: Drop it into React, Vue, vanilla JS, or any framework. One API, zero lock-in.
  • Front end, and Back end: SuperDoc can run in the browser or in NodeJS for direct connectivity with LLMs.
  • Highly extensible: Create your own custom extensions, commands, nodes and plugins.
  • Dual licensed: AGPLv3 for open source. Commercial for enterprise.
