  • Local-first architecture runs on Vite frontend with Node/Express daemon and SQLite storage, eliminating separate subscription costs for users with existing coding agent setup
  • Integrates with Claude Code, Codex CLI, Cursor Agent, Gemini CLI, OpenCode, and Qwen Code for flexible agent compatibility
  • Discovery form collects audience, tone, context, and constraints before generation; DESIGN.md files define visual direction, brand guidelines, typography, spacing, and anti-patterns
  • Outputs render in sandboxed iframe and export to HTML, PDF, ZIP, Markdown formats; early-stage project with quality dependent on underlying agent and model capabilities
