Comparison

Stesura vs Microsoft Word

Microsoft Word is the gold standard desktop word processor. It covers every document feature imaginable but is not designed to be embedded in a web app — and when it can be, the integration is complex and the UI is not yours to control.

In short

The desktop standard vs. an editor built to live in your product.

Nothing beats Word at being Word. It was simply never meant to live inside someone else's web app: a partner program, per-user licensing, and a UI that stays Microsoft's.

Stesura is a React component you brand, extend and control — and it reads and writes the .docx Word invented.

What is Microsoft Word?

Word is the most familiar document editor on the planet. Every word-processor feature exists in it, and its .docx format is the de facto standard for legal and enterprise documents. For web applications, however, it presents real challenges: embedding Word for the web goes through Microsoft's Cloud Storage Partner Program (WOPI), there is no React component, the UI stays Microsoft's, and business use generally needs Microsoft 365 licences. It is the right choice when you are building inside the Microsoft ecosystem — not when you are building a product that needs an editor embedded inside it.

DOCX import / export

Word is the reference implementation of .docx. Stesura's import/export is best effort — around 99% of content comes through intact in our round-trip test corpus — and legacy features (VML, frames, legacy EQ fields) are not supported.

Yes

Partial

Collaboration

Word co-authoring runs through Microsoft 365 (OneDrive / SharePoint); Stesura runs a server-authoritative backend you host.

Yes

Embeddable in a web app

Embedding Word for the web goes through Microsoft's Cloud Storage Partner Program and a WOPI integration — a partnership, not a component you install.

Partial

Yes

React component

Microsoft offers no React component for embedding Word; Office JS is for building add-ins inside Word.

Yes

UI customization

Word's interface is Microsoft's; add-ins can extend it but not replace it. Stesura's toolbar, menus, and layout are customizable.

Yes

ProseMirror API

Word extends through add-ins and macros, not through its document model. Stesura exposes the full ProseMirror schema and transaction API.

Yes

When to use which

Choose Microsoft Word when

Your enterprise is already standardized on Microsoft 365 and switching cost is prohibitive
Users expect full desktop-grade Word and will resist any deviation in behavior
You need the broader Microsoft ecosystem — Teams, SharePoint, PowerAutomate — deeply integrated
Embedding complexity and per-user Microsoft licensing are acceptable trade-offs
You also need Excel and PowerPoint alongside document editing

Choose Stesura when

You're embedding a word processor in a React app — not a simple text box
You need real pagination with accurate A4/Letter page layout
Legal numbering, footnotes, cross-references, and TOC are required out of the box
DOCX import and export that minimises round-trip losses — without binding your model to Word
You want complete document editing without months of assembly work
Track changes, comments, and per-section headers/footers must all work on day one
You want the full ProseMirror API while skipping the infrastructure
