Kombai vs Napkins.dev

Kombai is an AI design engineer for designing and coding websites and product interfaces. Users can explore work on an infinite canvas, ship code in a repository, and refine it in an editable browser. Its native Figma integration parses complex files, addresses messy grouping and invisible layers, and extracts icons and assets. Context Graphs give Kombai semantic understanding of repository code so it can reuse components, hooks, tokens, and types. It applies practices for more than 400 frontend libraries and frameworks, including React, Vue, Angular, Svelte, Next.js, Tailwind, shadcn/ui, and MUI. Kombai can test user flows in a browser and inspect console logs, network activity, performance data, and styles; it can also run lint and build checks and investigate runtime errors. Users can connect external services through MCP servers or run existing Claude Code or Codex subscriptions inside Kombai. It is available as a desktop app and IDE extension, but there is nothing to install on a phone. The Free plan has monthly credit limits; paid plans start at $20.00 per month.
