Kombai is an AI design engineer that designs distinctive websites and product UIs, then ships production-ready frontend code that reuses your existing components, tokens and design system.
About
Kombai is an AI design engineer for frontend work: it designs websites and product interfaces and then writes the production-ready code for them in the same workflow. It addresses a common complaint about AI-generated UI — that most models fall back on the same generic design patterns, producing interfaces that look alike — by making deliberate design decisions for each task rather than defaulting to familiar templates.
The product runs as a desktop app for macOS, Windows and Linux, and as an extension for popular IDEs including VS Code, Cursor, Antigravity, Trae and Kiro. Kombai combines an infinite design canvas for exploring ideas with a coding agent that works inside the user's real repository, reusing existing components, design tokens and hooks. It indexes the reusable code in a repo through its Context Graph feature, supports Figma import without MCP, and lets users pick from more than 50 AI models or rely on a built-in router to choose one per task. Kombai also publishes Kombai Gallery, a free library of over 20,000 curated UI designs usable with Kombai or other coding agents.

Who It's For
Kombai is aimed at frontend developers, product designers and design engineers who build websites and product UIs and want AI output that fits an existing codebase rather than producing generic code. It suits solo builders on the free and Pro tiers, and teams up to 20 seats on the Team plan, with Enterprise options for larger organizations needing SSO, audit logs and custom credit allowances. It is a domain-specific frontend tool, not a general-purpose coding agent, and is useful for teams with established design systems, Storybook setups or Figma files they want converted into production code.
