Kombai - 2026 Pricing, Features, Reviews & Alternatives

Kombai is an all-in-one design engineering agent delivered as an IDE extension, compatible with VS Code, Cursor, Antigravity, Trae, Kiro, and any Open VSX Registry-compatible IDE, with cloud access via browser. It operates in two distinct modes. Design Mode provides an infinite canvas for AI-generated UI creation, design system import from Figma, existing repositories, or webpages, and support for design tokens, reusable component libraries, screen-size variants, and light/dark mode versions. Canvas files are stored as HTML blocks with full animation support and participate in Git-based collaboration through standard commit, branch, and merge workflows on .canvas files. Code Mode scans existing codebases to construct a Context Graph, enabling semantic understanding of components, hooks, tokens, and types, and generates production-ready code that reuses existing repo assets, npm packages, and Storybook components. Built-in best practices cover 400+ frontend libraries, and browser-based verification draws on console logs, network activity, performance data, and computed styles. Automatic detection and fixing of lint, build, and runtime errors is included, along with parallel task threads and MCP integration for external services.

Kombai targets solo frontend developers, small development teams of up to 20 members, and larger enterprises with compliance and security requirements. A specialized Figma interpretation engine converts designs to production-ready code without requiring manual tagging, grouping, or Auto Layout configuration, recognizing design intent at a semantic level. A shared visual editor allows direct in-browser element updates to text and CSS, and a browser extension handles UI change syncing and autonomous user flow testing. Plan Mode previews structure, token usage, component reuse, and scope before any code is generated. Output supports React, HTML, CSS, and TypeScript. AI capabilities include an ensemble of deep learning and heuristics models, Context Graph construction, selectable LLM backends including Claude model variants, and asset generation via external generative image and video models.
