DESIGN.md is a free design-system file library from 02UI. Its core output is not a UI kit or an online design tool, but a set of Markdown files that can be read by AI coding tools. It is built for tools such as Google Stitch, Claude Code, Cursor, and Windsurf, helping define a product’s visual tone before AI generates the interface: color tokens, typography rules, component patterns, and overall style direction.
Its main positioning is “designer-first.” The site emphasizes that most DESIGN.md libraries are developer-oriented, while this project is aimed at designers. Each file does more than list rules: it also explains the reasoning behind decisions, avoiding the common problem of providing hex values without context. There are currently 3 style files available: Dark Tech Sharp, suitable for SaaS dashboards, developer tools, and AI products; Bold Editorial Motion, suitable for communities, cultural brands, membership clubs, sports, and lifestyle projects; and Textured Expressive, suitable for creative portfolios, agencies, and personal brands. The files are reverse-engineered from real websites, with references including Cursor.com, Champions4Good, and DesignByBrandin.
The pricing is very clear: Free forever, Open source, 0 Paywalls. Users can download the .md files directly or copy the text, and they can also leave an email address to receive new files every two weeks. For licensing, the page states that it is open source and free forever, but does not specify a license name. For commercial use, redistribution, or modification, it is still advisable to check the repository or the license information inside the files. In terms of compatibility, plain-text Markdown is naturally easy for AI tools to read, making it suitable for project rules, prompt context, or code-generation workflows.
The advantages are its low barrier to entry, clear structure, and well-explained design rationale. It is especially useful for designers who are already using AI to generate frontend pages. It can help teams align on a visual direction before generating interfaces, reducing the risk of AI output that “looks usable” but lacks a coherent system. The limitations are also clear: there are currently only 3 files, so the resource library is still small; there is no visible support for multi-user collaboration, version management, online editing, or team workflows; and it is not a complete design application in itself. Its value depends heavily on how well the rules are executed later inside AI coding tools.
The site does not provide information about access from mainland China, payment, or mirrors, so its China access status is unknown. Since no payment is required, payment friction is low; however, some of the AI tools it is designed for may face network or account restrictions in China. Alternatives include creating your own DESIGN.md files, maintaining Figma or design-system specification documents, or writing custom design rules in tools such as Cursor, Claude Code, and Windsurf. Overall, DESIGN.md is a good fit for individual designers, small teams, and AI prototyping workflows that want to quickly turn design standards into AI-readable context.
