What it is

Kombai is an AI design engineer for designing and coding websites and product interfaces. Users can explore work on an infinite canvas, ship code in a repository, and refine it in an editable browser. Its native Figma integration parses complex files, addresses messy grouping and invisible layers, and extracts icons and assets. Context Graphs give Kombai semantic understanding of repository code so it can reuse components, hooks, tokens, and types. It applies practices for more than 400 frontend libraries and frameworks, including React, Vue, Angular, Svelte, Next.js, Tailwind, shadcn/ui, and MUI. Kombai can test user flows in a browser and inspect console logs, network activity, performance data, and styles; it can also run lint and build checks and investigate runtime errors. Users can connect external services through MCP servers or run existing Claude Code or Codex subscriptions inside Kombai. It is available as a desktop app and IDE extension, but there is nothing to install on a phone. The Free plan has monthly credit limits; paid plans start at $20.00 per month.

Who it suits

Kombai suits developers and product teams who want to turn design inputs and repository context into frontend code, then check flows in a browser. It is available as a desktop app or IDE extension, not as a phone installation.

Kombai in depth

Read the full write-up

Kombai is built for frontend practitioners who want one workspace to move from visual concepts to maintainable repository code and verified browser behavior. It is most compelling for developers already working in desktop or IDE environments, while credit quotas and the lack of a phone installation make it less suitable for lightweight, occasional use.

Overview

The workflow spans an infinite design canvas, production code in an actual repository, and an editable browser for polishing the result. Inputs can be Figma files, existing codebases, or websites, so Kombai can join a project at several stages rather than requiring a blank-page start.

Its native Figma connection is practical for untidy source files: it parses complex documents, repairs problematic grouping and hidden layers, and pulls out icons and assets without requiring MCP. Context Graphs add semantic awareness of repository code, enabling reuse of established components, hooks, design tokens, and types. That repository continuity is a substantive advantage when consistency matters more than a one-off generated screen.

Key features

Kombai covers more than 400 frontend libraries and frameworks, including React, Vue, Angular, Svelte, Next.js, Tailwind, shadcn/ui, MUI, and Chakra. The range suits teams with varied stacks, although the value of that breadth depends on how closely a generated implementation matches a project’s own conventions.

Browser checks go beyond visual inspection. Kombai can run user flows autonomously and examine console output, network activity, performance information, and styles while verifying changes. It can also invoke project lint and build checks, investigate runtime failures, and work through fixes during a coding task. These capabilities make the tool more useful after generation, when integration defects are usually the expensive part of frontend work.

External services and data sources can be connected through MCP servers. Existing Claude Code or Codex subscriptions can run inside Kombai, and agents such as Claude Code, Codex, or Cursor can delegate frontend work through Kombai’s MCP server. That interoperability is valuable for teams already invested in agent workflows, but it also means the strongest setup is an ecosystem rather than a standalone casual editor.

Pricing

The Free plan costs $0/month and includes one seat. It starts with 150 credits, then supplies 50 credits per day up to 300 credits per month; unused credits can roll over to a maximum of 150. This is enough for evaluation and intermittent tasks, but the monthly ceiling can constrain sustained project work.

Pro costs $20/month for one seat and 2,000 credits per month, with rollover up to five times the monthly allowance. It adds email support and no AI training on your data. This is the sensible individual plan for regular development; the single-seat structure is not designed for a group.

Team costs $40 per user per month and supports up to 20 seats. It offers 2,000–110,000 shared credits monthly, unlimited credit rollovers, external-package indexing, shared rules and commands, plus centralized billing and management. The shared pool and administrative controls fit a coordinated team, while the per-user charge rises with headcount.

Enterprise uses custom pricing and adds a custom context engine, dedicated support, SOC2 compliance, onboarding services, custom service-level agreements, and tailored seats and credit allowance. It is aimed at organizations that need procurement and support commitments rather than a fixed self-serve quota.

Platforms

Kombai runs on Linux, macOS, and Windows as a desktop app, and as an IDE extension for VS Code, Cursor, Antigravity, Trae, and Kiro; installation is also offered through the Open VSX Registry. There is no phone installation, so mobile-only workflows are out. Desktop and IDE coverage is well matched to repository-based engineering.

Who it's for

Choose Kombai if you build frontend interfaces and want design import, repository-aware implementation, browser verification, and agent interoperability in one process. It is particularly suited to developers and teams maintaining an existing component system. It is a weaker fit for occasional users who will hit credit limits quickly, or for anyone expecting a phone or browser-only product.

Pros and cons

Pros: Figma handling addresses messy real-world files; Context Graphs encourage reuse of project code; browser, lint, build, and runtime checks extend the workflow beyond initial generation; broad framework coverage and MCP support accommodate varied stacks.

Cons: Free usage is capped at 300 credits per month with a limited rollover; Pro remains one seat; Team pricing scales per user; the product requires desktop or IDE installation and cannot be installed on a phone.

Data consideration: SOC2 compliance and listed encryption and malware controls support enterprise review, while personal information may be processed and stored worldwide and retained for service, legal, audit, dispute, and business needs.

Alternatives

Figma Make is the better choice for a Figma-centered macOS or web workflow, with a 150-AI-credit-per-day Starter allowance and a $16/month Professional full seat.

CoderUI suits web users seeking advanced customization, with a $29/month Pro plan and 500 credits monthly.

Locofy is worth considering when extension and web access matter; its free tier provides 2,000 LDMtokens for seven days before converting to Hobby.

Codia AI is a freemium option spanning API, extension, and web.

Fronty is a freemium API and web alternative that publishes to a free fronty.live address with branding.

v0 is preferable for web, iOS, or API use, with a free tier offering seven messages per day and Vercel deployment.

Builder.io offers API, extension, and web access, including a free tier with one user, 60 monthly Agent Credits, and one published app.

Calque is a free, self-hostable-oriented option available on Linux, macOS, Windows, and self-hosted setups.

Verdict

Kombai is a strong recommendation for frontend developers and teams that want design-to-code work grounded in an existing repository and followed by automated browser and project checks. Choose it for that joined workflow and its framework and agent reach; look elsewhere if your work is low-volume, mobile-first, or likely to outgrow credit limits without a team budget.

Verdict

Kombai brings design work, repository-aware coding, and browser checks into desktop and IDE workflows. Its free tier has credit limits, and phone installation is not offered.
