"It should be your call, not Anthropic's": Craft Anything hit 6k stars in 15 days, riding a controversy, backed by a company that already had 260k stars

Craft Anything is an open-source desktop app: you give it a website, app, or game, it studies the original, then your own Claude Code builds your version, which gets scored against the original and refined. Created Oct 31, by Nov 6 afternoon it had 17k stars and over 3 thousand forks. The stars didn't come mainly from the product: it caught the two hottest days of the "Anthropic blocks REA, bans game cloning" fight, and it sits on a team that gathered 260k stars in a single month. The method is learnable; this specific product is hard to copy.

A post that tagged Anthropic by name

2026 Oct 30, Anthropic's Addy Osmani confirmed on X that Claude Code had a new instruction: don't build "a clone of any existing game, even renamed or framed as original." His reason was one line: "Using Claude to infringe IP violates our usage policies." Before that, "Anthropic quietly blocked REA" had been spreading on r/claude and X for over a week. REA is the open-source reverse-engineering tool that went from under 10k stars to over 40 million in a month.

Two days later, Nov 1, ArtCraft's official account @get_artcraft posted:

We believe that you should have the final say in what you do with your property, and not @AnthropicAI. That's why we're dropping Craft Anything!

("We believe how you use your stuff should be up to you, not @AnthropicAI. So we're releasing Craft Anything!") The post drew about 127k views (quoted by madrobot.blog 11-02). The repo had gone up the afternoon before.

What it actually is

Usage is three steps: pick a target (URL, installed app, game, or file), type something like "rebuild this website" or "rebuild this game's mechanics in Rust," and hit start. It then runs four stages:

• Research: over three hundred inspection tools written from scratch in Rust, examining the original's pages, files, and runtime behavior at various screen widths, recording evidence for every finding;
• Build: drives Claude Code on your machine to write a new project in the language, framework, or engine you specify (games can target Unity, Unreal, or Godot);
• Compare: screenshots web pages at three screen widths and scores similarity; 90% is the passing line, otherwise it revises, up to 6 rounds;
• Finish: opens, plays, or previews your version, then takes change requests.

How it differs from REA: REA orchestrates external tools like Ghidra and IDA to help an agent "understand" software. Craft Anything ships its own disassembler and decompiler, has a GUI (simple and advanced modes), and adds the clone-and-score loop on top. The default is clean-room mode, which only looks at what a visitor can see (screenshots, text, layout, colors, fonts) and doesn't read the original's code. The repo even has a dedicated section explaining why this use fits Anthropic's terms.

But two things need to be clear. First, it runs on Claude Code itself, the unmodified version under your own account, which requires a paid subscription, and the usage counts against your quota. Second, it hasn't removed Anthropic's ban on cloning games; it just appends its own instructions, so some games still get refused (madrobot 11-02). The "REA replacement that Claude won't block" framing wasn't the project's own, and it overstates things. The project calls itself early alpha, current version v0.3.0.

How the stars grew

Daily stars (GitHub, as of 11-06):

The real spark was the 11-03 post. @rammcodes wrote: "Claude is blocking REA, so the team who recently built open-source Adobe alternatives also made a new alternative for REA." The repo itself never mentioned REA; "it exists because Claude blocked REA" is a story this post told for it. The two days after the post were the two fastest-growing days for stars. Whether it spread organically or was coordinated can't be seen from outside.

After that came the usual spread: It's FOSS posted a video on Facebook, several tech accounts on Instagram reposted the same copy, YouTube had "I had AI clone IMDb" style reviews, and sites in Italy and Hungary shared it. The README is in English, Japanese, Chinese, and Korean. On Trendshift's overall chart it ranked #11-02 on 2 and #11-03 on 1.

One channel didn't work: Hacker News. It got only one post there with 4 points (11-05), while REA had 814 points and 340 comments at the time. These stars came mostly from X and short-video audiences, not HN developers.

Who is behind it

The GitHub org is called storytold, publicly branded ArtCraft, founded by Brandon Thomas. From late September to early October the team shipped a string of "XCraft" projects: a well-known software product cloned with AI in Rust, open-source and free. PhotoCraft (targeting Photoshop) reached 77k stars, ArtCraft 39k, and PdfCraft, FilmCraft, WordCraft, and LightCraft each landed between 15k and 20k. They peaked in mid-October, covered by Phoronix, HN, and a pile of YouTube channels. By November the org's 33 repos had over 260k stars combined and 67k followers on GitHub.

Craft Anything is roughly number 16 in the series. Others were already building on it as soon as it dropped: 67k followers, a Discord, r/ArtCraftAI (where the official account posted "in response to Anthropic blocking REA, we built a version they can't block"), and ArtCraft Launcher, a one-click installer for the whole lineup that includes Craft Anything.

Development speed is part of their playbook too. Trendshift logged 7 days, 353 merged PRs, and 9 contributors, with three releases in about 50 hours. The main developer is AI: in PhotoCraft's last 100 commits, 56 were credited to Claude Opus 5.5.

So at the end of the day, these 17k stars are three things stacked on top of each other: a platform controversy that reached millions, an already-famous 260k-star brand, and a big account post that called it a "REA replacement." The product differences (built-in decompiler, side-by-side scoring, clean room) are what make that story hold up and give the press something to write about. But most of the people who starred it in 6 days probably never installed it or ran it even once: it needs a paid Claude Code, and the project is still alpha (inferred).

Who it's competing with

"Study one software product, then clone it" was already crowded in October. Even ArtCraft's own "XCraft clean-room clone" template got copied: BIMCraft 949 stars, solvecraft 365 stars, and others made clean-room clones of Auth0 and Salesforce.

If it were you

Verdict: C. Don't go head-on with this one. What's worth learning is its launch playbook. Its stars came from ArtCraft's existing 67k followers and 260k-star brand, plus a controversy past its peak, and you can't get any of that. The "clone any software" niche is also held down by REA at 430k stars, with dozens of copycat repos underneath.

Good fit for: developers who already have some audience (a few thousand GitHub followers, or an account that can hold its own on X or short video), who move fast and can ship a demoable thing in two or three days. What you should learn is the timing of "when the platform tightens, instantly side with users," plus the matrix approach of spinning out one template repeatedly.

Bad fit for: anyone thinking of building another "clone anything" or "REA replacement." The lane already has REA, replica-skill, Craft Anything, and a long tail of copycats, and the twentieth one will barely get stars. Also not for anyone betting the project on "getting around Anthropic's limits": Craft Anything itself didn't get around them, and the platform can tighten again anytime.

How to do it:

• Watch platform policy. When big companies tighten something (model refusals, API limits, store takedowns), users go looking for alternatives. An open-source version that runs and can be demoed within 48 hours beats a more complete one shipped two weeks later.
• State your stance in the launch post and name the platform. Lines like "your stuff, your call" will get reposted by the controversy itself.
• Turn legal anxiety into a feature: default to the safest mode, and write a dedicated section on "why this is compliant" so media and users feel safe resharing it.
• Narrow it down. The gaps it leaves are ready openings: don't tie it to Claude Code (support open models or other agents), or go deep on one target type (e.g., only cloning a certain kind of web component, or only one engine). Narrow projects are easier to remember within their own circle (inference).
• If you can keep shipping, copy its matrix approach: same naming, same template, and each new repo draws on the followers the older ones built up.

How to get users: Post the launch on X, and get one or two big accounts tied to the controversy to repost it (Craft Anything's fastest growth came right after @rammcodes' post). Prepare demos that can be cut into short videos (titles like "I had AI clone IMDb"). Ship a multilingual README from the start, and sites in Japan, Brazil, and Italy will repost it on their own. Don't count on HN: this kind of thing doesn't land there.

When: The buzz over "Anthropic bans REA / no cloning games" peaked from late October to early November. To ride this wave, act before mid-November. The more realistic move is to wait for the next platform crackdown and have your speed and templates ready in advance.

Signs that would mean you read it wrong:

1. Craft Anything's star growth holds over the next two weeks, and HN or dev communities start discussing real usage. That would show the product itself has users, not just narrative, and that the "do the parts it does badly" route is worth reassessing.
2. A similar library without big-brand backing (e.g. a clone tool for some Codex or open-source model version) reaches tens of thousands of stars in November. That would show this niche still has room.
3. Anthropic publicly states whether it allows or bans "wrapping Claude Code as the engine." If allowed, this category of tool heats up again. If banned, the line closes for good.
4. The reverse: ArtCraft's next Craft library drops to a few thousand stars, which would mean the matrix play is weakening, and the value of copying it shrinks too.
