What is Craft Anything?
Craft Anything, from the ArtCraft team, points at a target and works in four steps: it studies the original, has a coding agent build a new project in the stack you ask for, checks the build against the original, and refines it. Websites are compared at three screen widths; games can be rebuilt in Unity, Unreal or Godot. A Simple mode asks you plain questions; an Advanced workbench exposes functions, pseudo-C, disassembly, hex, call graphs and an evidence log.
Clean room is the default: nothing inside the original is read, only what a visitor sees, such as screenshots, visible text, layout, colours and fonts. Deep mode, for private use, reads code and files with its own decoders, disassembler and decompiler, plus Ghidra if installed. The engine has 320 tools, each also a CLI command and an MCP tool, covering native programs, .NET, Java, Android, Apple, Electron, websites, firmware, packet captures, databases and game files.
Building needs a coding agent on your machine; Claude Code is supported first and runs under your own sign-in. It is written in Rust, licensed MIT or Apache-2.0, in early alpha, with signed installers for Windows, macOS, Linux and FreeBSD and a WebAssembly build.
Is Craft Anything worth it?
The interesting part of Craft Anything is not the rebuild; it is the engine underneath. Its 320 tools, 300 of them in a pure-Rust engine with its own disassembler and decompiler, work without any AI at all and are exposed both as CLI commands and as MCP tools. An agent that can call core_evidence_browse and get answers with confidence and coverage attached is better placed than one guessing from screenshots.
The rebuild loop is newer and rougher. The repository was created on 31 October 2026 and reached v0.3.0 by 2 November, with 14,368 stars and 269 open issues and pull requests by 5 November. The README's own status list says only Claude Code has been run live as a builder; the Codex adapter is unverified, and of the agents reachable over ACP only Maki has been run live. Open issues report a hard-coded --model flag that ignores Claude Code settings (#922), failed asset generation without a fal.ai key (#923), and an Antigravity adapter that may break that provider's consumer terms (#929).
The clean-room default is the right instinct, and the README is careful about what it does and does not mean. Clean room limits what Craft Anything itself offers; it is not an operating-system sandbox, and the coding agent you run still acts with its own permissions. The builder also installs dependencies, and npm runs install scripts by default; the app asks before each new kind of command, but choosing always allow for npm stops it asking. It refuses DRM and anti-cheat work and is told not to copy logos, photos or text you do not own, yet whether a given rebuild is lawful is your problem, not the tool's.
As a learning and prototyping aid, studying how a site lays itself out and getting a working starting point in your own stack, it has no close open-source equivalent. As a production pipeline, it is a week old.
Where it earns its place
A front-end developer at a small agency
Get a working starting point that matches a reference site's layout in our own stack
Run craft-anything-cli rebuild with the site's address and the framework you want in clean-room mode; it captures the page at three widths, has Claude Code build it, and lists what still differs. Cost is your Claude usage; copy no logos or text you do not own.
A security researcher analysing a binary
Give an AI agent proper disassembly and decompilation tools
Run craft-anything-cli mcp and connect it to your MCP client with Deep mode on; the agent calls the engine's decoders and decompiler directly, with Ghidra used when installed, and every answer comes with evidence.
An indie game developer
Prototype a known game mechanic in Godot to study how it feels
Describe the mechanic with no target, for example rebuild - with a request and --rounds 1, and pick Godot; generated art and 3D models need your own fal.ai key.
Before you commit
- Setup
- Download an installer from Releases, or build with Rust 1.97 or newer (cargo run --release -p craft-anything); craft-anything-cli doctor checks for a signed-in coding agent and optional engines such as Ghidra.
- Integrations
- Claude Code first, Copilot CLI and other agents over ACP, a Codex adapter (unverified); Anthropic, OpenAI, OpenRouter or local OpenAI-compatible servers for questions; MCP server with 320 tools; fal.ai for generated assets.
- Data and privacy
- Projects stay in a local folder with captures, generated app, checks and evidence. Claude Code runs under your own account, which Craft Anything never sees. The builder installs and runs dependencies on your machine.
- Cost at scale
- Free software; real cost is coding-agent usage across several build and check rounds per project, plus fal.ai charges if you generate assets. A managed tier is listed as next, with no price.
- Limits
- Early alpha; behaviour checks for apps and games only partly there; some engine tools tested only against stand-ins; not an operating-system sandbox; ArtCraft brand assets must be removed from forks.
What’s good
- 320 inspection tools that work without any AI
- Every tool is a CLI command and an MCP tool
- Clean-room mode by default; Deep mode is opt-in
- Builds are checked against the original, not just generated
- Signed installers for Windows, macOS, Linux and FreeBSD
What’s not
- Early alpha, created 31 October 2026
- Only Claude Code verified live as a builder
- 269 open issues and pull requests
- Legal risk of each rebuild rests with the user
Best for
Developers and reverse engineers who want an MCP-accessible inspection engine and a Claude Code rebuild loop for prototypes and study, accepting alpha-quality software.
Craft Anything alternatives
Craft Anything: common questions
- Is Craft Anything worth it?
- An unusually capable inspection engine wrapped around a rebuild loop that is still early alpha, and one that puts the legal judgement squarely on you. We rate it 3.6 out of 5.
- How much does Craft Anything cost?
- Free under MIT or Apache-2.0. You pay for your coding agent (such as a Claude subscription) and optional fal.ai image generation; a managed tier is planned but not priced.
- What are the downsides of Craft Anything?
- Early alpha, created 31 October 2026; only Claude Code verified live as a builder; 269 open issues and pull requests; legal risk of each rebuild rests with the user.
- Who is Craft Anything best for?
- Developers and reverse engineers who want an MCP-accessible inspection engine and a Claude Code rebuild loop for prototypes and study, accepting alpha-quality software.
- How much does Craft Anything cost for a team or in production?
- Free software; real cost is coding-agent usage across several build and check rounds per project, plus fal.ai charges if you generate assets. A managed tier is listed as next, with no price.
- Is Craft Anything safe for company data?
- Projects stay in a local folder with captures, generated app, checks and evidence. Claude Code runs under your own account, which Craft Anything never sees. The builder installs and runs dependencies on your machine.
- What are the best Craft Anything alternatives?
- The closest alternatives we have reviewed are OpenCode.
