Software engineer Brandon Thomas has released free, open-source alternatives to Microsoft’s flagship productivity apps, taking direct aim at one of the world’s most entrenched software monopolies. His new ArtCraft Suite replicates Word, Excel and PowerPoint, and it was built with heavy help from AI.
The suite comprises three tools. WordCraft mirrors Microsoft Word, reaching roughly 88% parity with its ribbon commands. GridCraft replicates Excel, covering about 89% of commands and an impressive 98% of functions. DeckCraft stands in for PowerPoint, achieving around 79% feature parity.
What makes the project striking is how it was built. Thomas used the Rust programming language, with much of the code generated or assisted by Anthropic’s Claude AI, a vivid demonstration of how AI is collapsing the time and cost once required to build complex, professional-grade software.
The apps are notably versatile. They run natively and offline across Windows, macOS, Linux and BSD, and also work directly in web browsers, offering a flexibility that even Microsoft’s own ecosystem does not always match.
Crucially, the suite is free and open. Released under permissive MIT and Apache 2.0 licences via the ArtCraft GitHub project, the code can be freely used, modified and redistributed, inviting a global community of developers to improve it.
The move follows Thomas’s earlier free clones of Adobe’s creative tools, signalling a deliberate campaign against costly proprietary software.
Ultimately, ArtCraft shows how AI-assisted development could erode the dominance of incumbents, giving users powerful, no-cost alternatives to subscription-bound productivity giants.
