   Open-source .docx editor library for building document apps▲107

   We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0.

Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation. The core rendering engine is framework agnostic, with React and Vue ui adapters on top. It’s Apache 2.0. Happy to answer questions.

Everything else we found is screenshot-based or takes us out of the browser. We wanted something that felt quicker than screenshots and more integrated with the browsing experience. Instead of taking a screenshot, MarkUp snapshots the DOM in the current page, strips the…
