Spec score 8.0 #9 of 22 in AI UI Design Generators

What it is

Coherent is an AI design method for building multi-page products whose pages share components and a growing design system. It generates a Next.js project using Tailwind CSS and shadcn/ui, suitable as a prototype, developer handoff, or frontend. Shared components and editable design tokens propagate changes across pages, with design-system.config.ts as the editable configuration. Users can choose from 10 prebuilt atmospheres or define their own foundation. Coherent supplies context for Cursor, Claude Code, and other AI editors through.cursorrules and CLAUDE.md files. It supports Anthropic Claude or OpenAI GPT using the user’s own API key; typical model costs are estimated at $0.01–$0.03 per page. Its MCP server can validate code, read tokens, extract a design system from a URL, or apply a DESIGN.md file. It can import DESIGN.md and export tokens as W3C DTCG JSON, CSS variables, or Tailwind configuration. Full retrofit into an existing codebase is not supported yet, and direct Figma token import is also not supported. Coherent is open source under the MIT license and available on Linux, macOS, and Windows.
