Coherent vs EaseUI

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.

EaseUI is a web tool that turns natural-language prompts into user interfaces, with design tokens, component libraries and HTML/CSS exports. Each prompt generates six design variants, which users can review on an infinite canvas and refine using an inspector that displays and edits CSS properties in real time. EaseUI imports Figma frames to generate HTML and can send generated designs back as editable Figma layers. It can extract colors, typography, spacing, radii and shadows into structured tokens, and create component specimens. Exports include a single HTML file or a ZIP bundle with variants, design systems and a README. The tool supports Google Gemini, Anthropic Claude and OpenAI models. Designs, project data and API keys are stored in browser storage; clearing that data deletes local projects. The free plan provides one generation session of six variants, and another generation requires an upgrade. Premium costs $99, paid once, billed one-time.
