Programmable design engine for AI agents. Open-source.
Reframe is an innovative, open-source AI-native design engine tailored for developers and designers who want to integrate AI-driven design workflows into their projects. It leverages Claude Code subscriptions to spawn in-canvas AI agents without the need for API keys or token management, making it accessible and streamlined. The tool offers powerful features such as chat UI, right-click macros for quick rebranding, theming, scaling, rotating, and fixing designs, along with a comprehensive pipeline that transforms AI-generated code into structured HTML and DESIGN.md files. Its deterministic approach ensures consistent outputs, supported by a robust set of six MCP-native tools for design, compilation, inspection, editing, exporting, and project management. Ideal for those who want AI-enhanced design integrated directly into Git workflows, Reframe empowers developers to automate and fine-tune their UI/UX processes efficiently.
