Three ways to ship a Open SaaS-style UI.
Use in your AI builder, no-code tool, or CMS
Paste the DESIGN.md in and ask the tool to restyle your existing site to match this design, or start a brand new one from scratch with the same visual language.
Use in Claude Code, Cursor, Gemini, or your repo
Drop the DESIGN.md into your repo and ask the coding agent to refactor your existing design into this style, or build a new landing page from scratch.
Use as a design asset
Produce on-brand assets in this style. Banners, social posts, landing variants, marketing pages. Brand guidelines for designers and on-brand imagery from AI.
