Open-source AI tool 'Craft Anything' released to clone closed-source web and app projects

Japanese tech media outlet TechnoEdge reported on November 9, 2026, the release of "Craft Anything," an open-source AI tool designed to analyze the mechanisms of existing websites, applications, and games and use AI to generate independent versions with similar functionality, even when the original project's source code is not public.

Unlike traditional code generation assistants, Craft Anything provides a complete automated workflow consisting of four steps: "Study," "Build," "Check," and "Ready." Users simply specify the target they wish to emulate and describe their requirements, and the tool automatically executes the project generation process. During the build phase, the AI does not just write code but also compares the generated result visually and functionally against the original target (such as webpage display across different screen widths or game self-tests), iterating corrections until it closely resembles the original.

The tool includes 300 core engine tools, totaling 320 when including AI integration and setup utilities, capable of handling various objects such as PC and mobile apps, websites, and game files. For actual programming tasks, Craft Anything primarily relies on external AI agents, currently supporting Claude Code. Additionally, it can operate as a command-line interface (CLI) or MCP server, allowing developers to call its parsing engine directly from existing AI toolchains.

Craft Anything offers two main analysis modes: the "Clean room" mode analyzes only visible information such as screenshots, layout measurements, and colors without reading any internal code; while the "Deep" mode allows reading internal code and JavaScript using built-in engines or Ghidra, suitable for private use. The tool is currently in Alpha testing and is open-sourced under a dual MIT or Apache-2.0 license.
