Open Design is a project officially open sourced by @ tuturetom (co-founder and CEO of http://(Nexu. io)) in April 2026, positioned as a local first, high fidelity open-source alternative to Anthropic Claude Design. It completed 18700+lines of code in just 72 hours, achieving over 95% fidelity, fully reversing and condensing Claude Design's most advanced design workflow, exquisite templates, and experience. The project adopts Apache 2.0 fully open source, GitHub address: https://(github.com)/nexu-io/open-design Main functional highlights • Supports 30+top-level design skills that can be combined (including exquisite templates widely circulated on Twitter) Built in 71+brand level design systems (industry-leading systems such as Linear, Stripe, Apple, etc., can be directly replicated with just one click) Compatible with 16+Code Agents (Claude Code, cursor, Codex, Gemini, OpenClaw, OpenCode, etc.) • Local Daemon mode: Automatically detects all AI code agents on your computer's PATH, allowing you to easily reuse the large membership amount you have already paid for with just one click Local file system mapping+sketch to prototype: can directly read local project files, preview any file, and instantly turn hand drawn sketches into high fidelity prototypes • Complete Agent Guidance Mechanism: Built in interactive forms, visual style selectors, TODO introspection system, ensuring that the output Web/Mobile prototypes and Slides can achieve the quality of "direct production" and support continuous follow-up and modification One click export and preview: Supports HTML, PDF, PPTX, MP4 and other formats, with built-in sandbox for real-time preview, allowing for direct demonstration and sharing
