WordCraft vs Microsoft Word
A task-led comparison for people who need .docx files to open, look right and reach colleagues unchanged.
WordCraft is an open-source, clean-room word processor written in pure Rust, currently in alpha, and it is not Microsoft Word. Microsoft Word is Microsoft's commercial word processor. The WordCraft README describes WordCraft as a reimplementation of it; this page has not tested that claim. In this guide, WordCraft means only the ArtCraft word processor, not the English word “word”.

Evidence and method
checked 2026-10-16WordCraft facts come from the official WordCraft page, the GitHub README and the v0.5.0 release page, all read on 2026-10-16. Microsoft Word facts come only from Microsoft's public Word product page and its Word feature comparison on support.microsoft.com, read on the same day, and they appear here only as categories. Where a row is Microsoft's own claim, the table says so.
We did not install or run either product for this page, so nothing here reports our own test results. Prices, version numbers, market share and benchmark results are left out on purpose. The 88% figure in the WordCraft README is the project's own estimate of ribbon-feature coverage, counted by command; this page does not repeat it as a comparison result.
Who this comparison helps
Use this page if you are checking whether WordCraft can take over part of a .docx workflow from Microsoft Word, or if you want an open-source editor for some of your files. If your work depends on desktop-only Word features, read the table first: the rows that name desktop are where the two products differ on public information.
What to verify
- Open three real .docx files from your work in WordCraft v0.5.0: one with tables, one with tracked changes and one with pictures or shapes.
- Save each file, reopen it in Microsoft Word, and compare the page count, line breaks and tracked changes.
- Test charts and SmartArt. The README lists keeping them through a round trip as a Beta target.
- Test mail merge with your own CSV file, and check every letter or label before you print. The release notes say File › Print opens the document in the system PDF viewer; the README lists native printing as Beta work.
- Confirm the platform, the build and the checksum on the v0.5.0 release page before you install.
Questions readers ask
Is WordCraft a replacement for Microsoft Word?
Not yet, by the project's own account. The README says WordCraft is in alpha and lists testing against real-world .docx files, keeping charts and SmartArt through a round trip, and pagination closer to Word's as Beta work. Decide by testing your own files.
Is WordCraft made by Microsoft?
No. The README states that WordCraft is not affiliated with, sponsored by or endorsed by Microsoft Corporation. Microsoft and Microsoft Word are trademarks of the Microsoft group of companies.
Which one should I test first?
Test the one your files already depend on. If your documents rely on desktop-only Word features, check those in WordCraft first. If you need to edit in a browser on shared files, check Word for the web as well.
What this page does not claim
It does not name a winner, run a benchmark or claim that WordCraft matches Microsoft Word feature for feature. It is an editorial comparison built from public pages, and a mention on this fan-made site is not an endorsement by Microsoft or ArtCraft.
