Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 11 of the 52 other AI app builders we grade
Kombai is an AI agent for frontend work. It explores designs on an infinite canvas, reads the components, tokens and hooks in your repo, Figma file or Storybook, and writes code in your stack. It runs as a desktop app and as an extension for VS Code and Cursor, and it offers 50+ models.
To get you started, here are 9 things to know about Kombai, taken from its own pages and our grades.
It needs setting up against your repo, design system or Figma.
- 1
Best for UI coding inside your own repo
Kombai is a desktop app and editor extension that designs on a canvas and codes in your repo, reusing your components.
- 2
Paid plans start at $16 a month
As its pricing page puts it: $16 per month, billed annually ($20 billed monthly).
- 3
There is a free plan
150 credits on sign-up, then 50 credits a day up to 300 a month, with rollovers up to half the monthly limit.
- 4
It runs on 3 platforms
macOS, Windows and Linux, with a browser extension too.
- 5
Infinite canvas
Explore ideas on a canvas before they touch production code, with parallel agents, targeted variations and live HTML, states and animations.
- 6
Repo-aware coding

A 2.2 GPA, above 11 of 52
That is against the other AI app builders we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it

The report card
Best for UI coding inside your own repo
Kombai is a desktop app and editor extension that designs on a canvas and codes in your repo, reusing your components. Free is 300 credits a month. It has no web version, and shared credits and rules need Team at $32 and up.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Pro is $16 a month on yearly billing, at the cheap end of the category's range, for 2,000 credits. Team starts at $32. |
| Free plan and trial | C | Free: 300 credits a month (50 a day), one seat. Enough to try, not to ship with. |
| Features | C | Canvas, repo-aware coding, Storybook, 50+ models and a built-in browser. Indexing private packages is Team only and a custom context engine is Enterprise. |
| Ease of use | C | No store rating on record. It needs setting up against your repo, design system or Figma. |
| Platforms and integrations | C | Mac, Windows, Linux and editor extensions, which is computers only. No web editor or phone app is listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Kombai is for
- Fits if your team has a React repo and a design system to build against
- Works for front-end developers who already use Cursor or VS Code
Who it is not for
- Tight if you stay free: 300 credits a month, 50 a day
- Skip it if you want a web app: only desktop apps and extensions are listed
- Watch out: shared credits, shared rules and up to 20 seats need Team at $32 and up
- Watch out: credit tiers go up to 110,000 a month and each step costs more
Good to know
Good for

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Kombai you would be making a tool that builds and hosts other apps. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 27 of the 52 other AI app builders grade higher. It costs $192 a year.
What you could not
- A tool that builds and hosts other apps.
- An AI agent, with the models and the safeguards behind it.
- Apps for macOS, Windows and Linux that stay in step with each other.
- Several people working in it at the same moment.
- It plugs into other products, Figma, Storybook and VS Code among them.
What this rests on. Kombai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
