Why It's Strong
The 27 deterministic rules align with Loam's 60/30/10 layer triage — most design checks are Layer 1 (deterministic), not Layer 3 (LLM). The tool runs the deterministic rules first, then uses LLM critique only where judgment is needed.
Also detects AI-generated design fingerprints.
Known Issues
- Live mode can disconnect
- Component selection finicky on deeply nested DOM
adaptcommand can break layouts- Monorepo file targeting has edge cases
Requirements
- Node.js (pnpm or Bun)
- Puppeteer for CLI mode
- No API keys needed for deterministic rules
Notes
- Apache-2.0 license, actively maintained
- Strongest design tool evaluated
- Frontend-focused — no value for backend-only projects
