The coding agent built
for frontend engineering

Ship production-grade frontends faster, without fighting your agent. Kombai natively handles the complexities that general-purpose agents often struggle with: library-specific quirks, component reuse, design handoffs, accessibility, and more.

Codes like it's been on your team

Always-on best practices for your stack

Kombai scans your repo, understands your whole stack, and applies human-tested best practices for 400+ frontend libraries.

Consistent reuse from repo, npm, and Storybook

Context Graphs give Kombai a semantic understanding of your code, so it reuses what’s already there: components, hooks, tokens, and types.

Agentic superpowers, built for frontend work

Skills Library

Choose from a wide range of developer-tested skills for everyday frontend tasks. Improve UIs, fix SEO and accessibility issues, sync your Design System with your codebase, and more.

Plan and Debug Modes

Tackle complex features and difficult bugs with a clear approach. Review the plan before implementation, investigate what’s going wrong, and work through fixes step by step.

Native Figma Integration

Parses complex design files, fixes common issues like messy grouping and invisible layers, and extracts icons and assets. No MCP needed.

Choose your model or router

Select a model yourself, or let Kombai's built-in router choose for you.

Refine and test your work

Edit your UI visually

Adjust text, styles, and layout in the browser, and send the changes to the agent for implementation.

Autonomous browser testing

Kombai autonomously tests user flows and verifies changes in the browser, with access to console logs, network activity, performance data, and styles.

Run checks and fix errors

Kombai can run your project’s lint and build checks, investigate runtime errors, and work through fixes as part of a coding task.

Frontend expertise, wherever you work.

What makes Kombai useful for frontend development?
Kombai combines best practices for 400+ frontend libraries with tools built for frontend work. It understands Figma designs, finds reusable code through Context Graphs, and can test the running UI in the browser. These capabilities help it carry a frontend task from implementation through verification.
Can I add features to an existing app?
Yes. Open your repo and describe what you want to build or change. Kombai reads your existing code and tech stack, then works directly in your project. You can add new features, update existing screens, or work through bugs.
Will Kombai work with my frontend stack?
Kombai includes human-tested best practices for 400+ libraries and frameworks, including React, Vue, Angular, Svelte, Next.js, Tailwind, shadcn/ui, and MUI. It detects your project’s stack, and you can review or adjust that configuration.
Will Kombai reuse my components and follow my coding conventions?
Yes. Context Graphs help Kombai find and reuse components, hooks, tokens, and types from the repo, npm packages, and Storybook sources you index. Project rules, including existing AGENTS.md instructions, guide how it writes and organizes code.
Can I keep using my current coding agent?
Yes. Run your installed Claude Code or Codex CLI inside Kombai using your existing subscription. Or keep working in your preferred agent and delegate frontend tasks to Kombai through the Kombai MCP server.
Can I add my own skills or connect external tools?
Yes. Create or import skills and custom commands for your team’s workflows. You can also connect external services and data sources to Kombai through their MCP servers.
