Feature & Specification Comparison

Specification	Raven Architecture & Design	Uxloom uxloom-dev Architecture & Design
Summary	Design intelligence for AI-generated UI — principles, patterns, content, brand, design tokens.	Agent-native UI/UX design validation: model user journeys as state machines and prove what AI-generated screens are missing (unreachable states, missing empty/loading/error states, WCAG contrast, touch targets, localization overflow) before code exists — then verify the code implements the contract. Deterministic CI gates (uxloom check, uxloom audit), one-command setup (npx uxloom init).
