Kombai

AI design engineer for frontend work that explores UI designs on a canvas and writes code matching your repo, with a free credit plan.

Freemium

What is Kombai?

Kombai is an AI tool for frontend and UI work that combines a design mode with a coding agent. You explore layouts on an infinite canvas, generate variations, edit designs and export HTML or images, then hand the chosen direction to an agent that writes code to suit your existing repository. The agent builds context graphs, can index Storybook and private packages, and offers plan and debug modes, a built-in browser for testing, Figma integration, MCP support and parallel agents. Usage is measured in credits, and a model or router you pick sets how quickly a task consumes them. The Free plan gives 150 credits at sign-up plus 50 a day up to 300 a month. Pro starts at $20 per month for 2,000 credits, or $16 per month billed annually, and Team costs $40 per user per month.

Use cases

  • Design a landing page on an infinite canvas
  • Generate several variations of a UI
  • Turn a chosen design into frontend code
  • Match new components to an existing codebase
  • Index Storybook for component reuse
  • Test changes in a built-in browser

Who it's for

  • Frontend developers
  • Design engineers
  • Product designers
  • Startup founders

Why use Kombai

  • Design and implementation happen in one tool, so a chosen layout does not need to be rebuilt by hand.
  • The agent reads your repository and component libraries, which helps generated code fit existing patterns.
  • A model router and multiplier system let you spend fewer credits on simple tasks.
  • One-time credit packs do not expire, so a heavy week does not force a plan change.
  • The Pro plan states that your data is not used for AI training.
