# 'Software is over'

Full title: 'Software is over': ArtCraft's Brandon Thomas uses Claude Opus 5.5 to build open-source Rust clones of seven Adobe apps, then Office

Between Sept 30 and Oct 1, 2026, developer Brandon Thomas (ArtCraft, ex-Storyteller.ai) published seven open-source, "clean-room" reimplementations of Adobe apps written in pure Rust with Anthropic's Claude Opus 5.5: PhotoCraft (Photoshop), VectorCraft (Illustrator), FilmCraft (Premiere Pro), LightCraft (Lightroom), EffectCraft (After Effects), DesignCraft (InDesign) and PdfCraft (Acrobat). He declared "software is over". PhotoCraft passed 33k GitHub stars within ten days. On Oct 7 he added clones of Word, Excel, PowerPoint, AutoCAD and Pro Tools.

## Key facts
- Repos under github.com/storytold, created Sept 30–Oct 1, 2026, licensed MIT or Apache-2.0, marked 'early alpha'; native apps for macOS, Windows, Linux, FreeBSD plus web (WebAssembly)
- GitHub stars on Oct 9, 2026 (GitHub API): PhotoCraft ~33.1k, LightCraft ~7.2k, FilmCraft ~6.6k, PdfCraft ~5.8k, VectorCraft ~4.8k, EffectCraft ~3.6k, DesignCraft ~2.0k. PhotoCraft had ~6.7k stars on Oct 7, a week after its first commit
- Built with Claude Opus 5.5; Thomas says he has used Rust for about a decade. Coverage: Ars Technica, TechSpot, PetaPixel, VideoCardz (Oct 7)
- Parity: Thomas acknowledges around 50% feature parity. He first promised 100% within a month, then said '99% parity will take a while… measured in months and not years'. He pays bug bounties
- Motivation: frustration with Adobe's subscription cancellation fee
- Oct 7 expansion: WordCraft (Microsoft Word), GridCraft (Excel), DeckCraft (PowerPoint), CadCraft (AutoCAD) and SoundCraft (Avid Pro Tools), each ~0.8–1.4k stars by Oct 9
- No Adobe response reported; commentators flagged possible legal risk from close interface imitation

## What happened

Brandon Thomas founded ArtCraft about a year ago. He previously ran Storyteller.ai and worked as an engineer at Square. Over two days he published
seven Rust applications, each a "clean-room reimplementation" of a major Adobe Creative Cloud app, and said Anthropic's Claude Opus 5.5
wrote them. The projects spread on Reddit and Hacker News over the weekend and went viral on GitHub. A week later, on October 7, he added
equivalents of Microsoft Word, Excel and PowerPoint, AutoCAD and Pro Tools.

The apps are early alphas. Thomas puts feature parity at about 50%.

## Why it matters

It is the most visible test so far of the claim that frontier coding agents make large, established desktop software cheap to copy.
How much of it is truly usable, and whether it survives a legal challenge, remains to be seen.
