Kombai

Kombai is an AI frontend agent that turns Figma designs and prompts into code that fits your existing repository, built for frontend developers and design engineers. General coding agents often produce UI that ignores your design system; Kombai's angle is context, reading your components, tokens and Storybook so new screens look like the rest of your product. It calls itself an AI design engineer, and it adds a design canvas so you can explore options before any code lands.

What is Kombai used for?

Teams use Kombai to speed up the slowest part of frontend work: translating designs into clean, consistent code that matches the existing codebase.

• Importing Figma designs natively, fixing messy grouping and invisible layers, and extracting icons and assets
• Generating frontend code that reuses your existing components, tokens and patterns
• Indexing Storybook so the agent knows your component library
• Exploring layout variations and design systems on an infinite canvas, with HTML and image export
• Refining and testing results in a built-in browser
• Working from a desktop app or extensions for VS Code, Cursor, Antigravity, Trae and Kiro

Who Kombai is best for

Kombai fits frontend engineers who receive Figma files from designers, design engineers who move between canvas and code, and product teams with an established component library. It also suits solo developers who want polished UI without hand-writing every layout. Backend developers and teams that need full-stack app generation from scratch will get more from a general app builder or coding agent.

Kombai pricing

As of October 2026, Kombai's free plan gives up to 300 credits a month: 150 on sign-up, then 50 a day up to the cap, for one seat with community support. Pro costs $20 per month for 2,000 credits, one seat, larger rollover, email support, no AI training on your data and SOC 2. Team costs $40 per user per month with pooled credits from 2,000 to 110,000 a month, up to 20 seats, shared rules and commands, indexing of external packages and usage analytics. Enterprise is custom and adds a custom context engine, SSO, audit logs and SLAs. Quarterly and yearly billing are available, with yearly saving 20%.

Limitations to keep in mind

• It is built for frontend and UI work, so backend and data logic are out of scope
• Free credits go quickly on large, multi-section pages
• Output quality depends on how clean and well-structured the Figma file is
• Library support claims should be checked against your exact stack

Kombai vs alternatives

v0 by Vercel is the most popular prompt-to-UI tool and is strong for React and Next.js prototypes, but it works best on new UI rather than inside your existing repo. Onlook is a visual editor for React apps and suits people who want to edit layouts directly in the browser. Lovable builds whole web apps from prompts, which is better when you need a backend too. Cursor is a general AI editor that can write UI, though without Figma import or a design canvas. Kombai wins when matching your existing design system and converting Figma files are the main jobs.

Tips for getting started with Kombai

Install the extension in the editor you already use and open your real repository so Kombai can learn your components. Point it at your Storybook if you have one. Clean up obvious issues in the Figma file, such as unnamed layers, before importing. Start with a single component or page section to see how well it matches your patterns before converting full pages.
