Is Kombai worth it?
Kombai is worth a try if generic AI-made interfaces frustrate you.
It pairs a design canvas with a coding agent that reads your repo, Storybook and Figma files, then reuses your own components and tokens. The free plan lets you test it on a real project. The caution is that its originality improvements are measured on a benchmark the company built, and credits are the real limit on how much you can do each month.
What is Kombai?
Kombai is an AI design engineer for websites and product interfaces.
The company says it helps you design and code standout interfaces that do not look like AI slop. It runs as a desktop app for macOS, Windows and Linux and as an extension for editors such as VS Code, Cursor, Antigravity, Trae and Kiro. The homepage reports 800K+ installs.
How Kombai makes design decisions
A taste agent identifies the key design decisions for each task and makes choices instead of falling back on AI defaults. It draws inspiration from 20k+ curated pages and sections, and stays consistent with your brief and repo.
How Kombai fits your codebase
Context Graphs reuse components, tokens and hooks from your repo, npm package or Storybook. Kombai says it codes in your stack with best practices for 400+ libraries, so new work should look like part of your product.
Is Kombai legit and safe to use?
Kombai names its company and lists security and privacy commitments on its pricing page.
The terms of service are published by Kombai, Inc. and were last modified on 6 January 2026. The Pro plan lists SOC2 compliance and no AI training on your data. These are the company's own statements, so teams with procurement rules should ask for the underlying documents. The Enterprise tier also lists a custom context engine, onboarding services and custom SLAs.
Support channels at Kombai
Support is by email at support@kombai.com, and the support page says replies usually come within two hours. You can also reach the team on X and Reddit. Higher tiers list dedicated support, onboarding and custom service terms.
How we evaluated Kombai
This review is based on reading Kombai's own pages, not on using the tool.
Toolavero read the homepage, the pricing page, the design features page, the support page, the terms of service and the privacy policy. Toolavero did not sign up for or test Kombai, so claims about originality, library coverage and model quality come from the company and were not checked independently.
Kombai output quality and limits
Kombai backs its claims with its own benchmark, which readers should treat with care.
In its own Design Creativity Bench evals, Kombai says it improves originality by up to 13 percentage points and creative range by up to 23 percentage points. The benchmark and the tool come from the same company. Independent results may differ, so try your own briefs and compare them against your usual output before trusting the numbers.
What Kombai canvas output is
Canvas designs are editable HTML, not finished app code. Kombai advises implementing a design in your framework, running checks and reviewing the code before merging, which is sensible advice for any generated code.
Kombai key features
Kombai combines a design canvas, a coding agent and a model choice.
Designs can be explored on infinite canvases with parallel agents, then turned into code in your project.
Canvas and editing in Kombai
You can edit text, styles and layout of any element, create targeted variations or full redesigns, and work with live HTML, states and animations. Canvas files can sit in your project folders and be versioned with Git.
Figma, MCP and models
A native Figma integration needs no MCP. A Kombai MCP server lets Claude Code, Codex or Cursor delegate design work. You can pick from 50+ models from providers including Claude, GPT, Grok and Kimi, or let a built-in router choose.
Kombai pricing and plans
Plans are credit-based, with a free tier that refills daily.
Free is $0 per month with 300 credits per month: 150 on sign-up and 50 credits daily. Pro is $20 per month with 2,000 credits per month, rollovers up to 5x monthly and email support. Team is $40 per month, with a shared credit pool, unlimited rollovers and seats for up to 20 members. Enterprise is custom. Yearly billing is shown as saving 20%.
Support, refunds and cancellation
Cancellation is straightforward, but the pages do not describe refunds.
You can switch plans, pause or cancel from the Subscription and Billing page. Cancellations take effect at the end of the current cycle, so paid credits stay until then. One-time credit packs do not expire. Paused or cancelled plans are managed on the same page, which keeps billing changes simple. Check your credit balance before cancelling.
Email support for Kombai
Email support at support@kombai.com is listed with a stated reply time of two hours. The pages read do not mention a money-back guarantee, so ask support before buying a long term.
Who should use Kombai
Kombai suits frontend developers and small product teams.
People who already have a design system, Storybook or Figma files will get the most from its context tools. Designers who want to explore directions before coding can use the canvas. Those who want a simple chat assistant, or who rarely build interfaces, may find the credit model more than they need. Solo builders can start on the free plan and test one feature.
Final verdict on Kombai
Kombai is a focused tool for teams that care how their UI looks.
The design canvas, repo awareness and model choice are the strengths. The limits are credits and a benchmark that the company runs itself. This Kombai review suggests starting on the free plan with one real feature before moving to Pro. Judge it on your own briefs, not on the benchmark.
