A set of open-source creative apps written by developer Brandon Thomas with Claude Opus 5.5 keeps widening its reach on GitHub. The first seven announced apps targeted Adobe's Photoshop, Illustrator, Premiere, Lightroom, After Effects, InDesign and Acrobat. As of the afternoon of October 12 Beijing time, the same account has four new repositories that explicitly name Microsoft Word, Excel, PowerPoint and AutoCAD as their targets.
Thomas has 15 years of engineering experience, has worked at Square, and served as CEO of Storyteller.ai. He gave the whole batch a shared suffix: PhotoCraft, VectorCraft, FilmCraft, LightCraft, EffectCraft, DesignCraft and PdfCraft, plus the newly added WordCraft, GridCraft, DeckCraft and CADCraft, together known as the ArtCraft series. Everything is written in Rust and licensed under either MIT or Apache-2.0, at the user's choice.
Key moments over twelve days
GitHub's repository records make it possible to reconstruct the timeline. Five repositories — PhotoCraft, FilmCraft, LightCraft, PdfCraft and VectorCraft — were created on September 30, and EffectCraft and DesignCraft followed on October 1. Over the weekend after that, Thomas pushed the whole lineup on Reddit under the slogan “Software is over.” Around October 7, several international outlets picked up the story, and on the same day WordCraft, GridCraft, DeckCraft and CADCraft were created under the same account.
Attention is concentrated on the Photoshop counterpart. An earlier report tallied more than 42,000 stars across the seven repositories, with PhotoCraft alone accounting for 23,303. According to GitHub API data from the afternoon of October 12, PhotoCraft has reached 49,075 stars and 7,919 forks, with 1,259 open issues and pull requests combined. The others trail well behind: FilmCraft and LightCraft have about 10,400 each, PdfCraft has 9,973, the new WordCraft has 6,741, and DeckCraft, the most recent to appear, has 2,124.
A small ecosystem is already forming around it. On October 10 a plugin repository appeared that connects ComfyUI workflows to PhotoCraft, and on October 6 someone created an “independent source snapshot” that notes the original license and attribution are retained, kept as a backup.
What the repositories say
PhotoCraft's documentation says its menus, shortcuts and panels follow Photoshop conventions, and that rendering uses wgpu-based GPU compositing covering Metal, Vulkan, DX12 and WebGPU, with macOS, Windows, Linux, FreeBSD and the web listed as supported platforms. For PSD support it gives one concrete figure: after re-saving the 309 test files from the open-source psd-tools library, 307 rendered results stayed unchanged.
Another design choice targets AI agents: every operation is a command, and the same engine can be driven from the interface, the command line, a JSON control channel or an MCP server. The screenshots in the documentation were rendered off-screen through that control channel.
The status bar reads early alpha. Thomas first said on Reddit that full feature parity with Adobe would take a month, then softened his stance on Hacker News, saying that 99% parity would “take a while,” counted in months rather than years. He himself acknowledges that stability, performance and edge cases in professional workflows remain unsolved.
The “clean-room” claim
Each repository's description says clean-room reimplementation, meaning it was rewritten from public specifications and observable behavior without using the other party's source code or assets. Some Hacker News commenters rejected that use of the term: traditional clean-room development splits two teams, one writing the specification and the other implementing from it, whereas here it is one person plus a model trained on public code and documentation, and outsiders cannot check what the model has seen.
On trademarks, the documentation states that names such as Adobe and Photoshop belong to Adobe, and that ArtCraft's own name and logo are not covered by the open-source licenses, so forks must remove them. Patents are a separate matter: Adobe holds thousands of them, and no one has yet offered a judgment on whether any could apply to an interface or feature here. Adobe had not responded when PetaPixel published, and Microsoft has likewise made no public statement on the Office look-alikes.
On the business model, the basic features carry no subscription fee, while generative AI features run on a separate credit system: users can subscribe, buy credits one-off, or connect their own compute and third-party keys. The four Office look-alikes are less than a week old, and how far they are from being usable is shown more plainly by the issue lists in the repositories than by any slogan.
