Kombai
Also known as: Kombai AI
Kombai is a frontend coding agent from Kombai, Inc. that calls itself an AI design engineer. It runs as a desktop app and as an extension for VS Code, Cursor, Windsurf and other editors, designs screens on a canvas, then writes production code into the customer's own repository, reusing components, tokens and hooks it indexes from the repo, npm packages and Storybook. It drives a browser to check its work. Plans run from free to Pro at $20 a month and Team at $40 a month.
Kombai is built by Kombai, Inc., a company that lists 2022 as its founding year and places its terms under California law. It sells one product in two forms, a desktop app for macOS, Windows and Linux and an extension for VS Code, Cursor, Windsurf, Antigravity, Trae, Kiro and Devin Desktop, and calls it an AI design engineer. Work starts on a canvas, where Design mode draws three variations of a screen by default, and moves into the customer's own repository, where the agent writes the chosen design as code that reuses the project's components, design tokens and hooks.
Before writing, Kombai builds Context Graphs, an index of the components, hooks, tokens and types in the workspace, in npm packages and, on Team, in Storybook, which teammates can share. Design systems persist as files built from a codebase, a Figma file, a live website or a canvas, and a Figma import reads one frame through Figma's own sign in.
The agent can plan first in an editable plan, runs parallel agents across canvases and Git worktrees, runs terminal commands under three approval settings, keeps a per project memory that users can view, edit and delete, and calls external MCP servers.
It drives an in app browser or Chrome to click through and fill in what it built, runs the project's lint and build checks with accessibility and SEO audits, and shows every change as a diff with checkpoints, opening a GitHub pull request from a worktree for review and merge.
Free includes 300 credits a month. Pro costs $20 a month for 2,000 credits, or $16 a month billed yearly, with larger tiers up to 110,000 credits for $1,000 a month, and Team is listed at $40 a month, priced as a shared credit allowance plus $10 a seat for up to 20 seats, with shared rules and commands, Storybook indexing and usage analytics. Enterprise is by contact and adds single sign on with SAML, audit logs, custom data retention and a DPA.
Each chat can use one of 32 language models from 12 providers or an Auto router, billed at different credit rates, and local agents can run on a developer's own Claude Code or Codex subscription. Kombai says it does not train AI on customer data, lists SOC 2 compliance on its trust center without naming a type, and runs its service on AWS with no stated region or self hosted option.
It fits frontend teams that want design exploration and production UI code in one tool, companies with an established component library and design system they want an agent to reuse, and developers who want to hand design work to Kombai from Claude Code, Codex or Cursor through its MCP server and plugins. It fits less well for buyers who need agents started by schedules, webhooks or issue trackers, a public API, a choice of hosting region, or an agent built for backend work.

Integrations
Figma through Figma's OAuth for reading frames, with copy and paste to Figma through the clipboard; GitHub pull requests from worktree chats through the GitHub CLI or GitHub's compare page; npm packages and Storybook indexed from a folder or Git address; an MCP client for external servers over stdio, SSE and streamable HTTP with OAuth; and a local Kombai MCP server with plugins for Claude Code, Codex, ChatGPT Desktop and Claude Desktop, plus setup for Cursor, VS Code, Antigravity and Gemini CLI.
In practice
A frontend developer pastes a Figma frame link into Kombai inside Cursor. The agent reads the frame, matches it against the Context Graph of the team's React components and tokens, writes the page with the existing Button and Card components, runs the lint and build checks, then opens the page in Chrome to click through the form before the developer reviews the diff.
A product designer at a SaaS company asks Design mode for three takes on a new onboarding screen in the company's design system, iterates on one in the canvas, and hands it to a parallel agent in its own worktree, which writes the code and opens a GitHub pull request for an engineer to review.
An engineer working in Claude Code installs the Kombai plugin and asks it to improve a settings page, and Kombai runs its Improve UI skill with accessibility and SEO audits, returning code changes in the same repository.

Figma connects through Figma's own OAuth, and the agent reads one frame at a time from a link, while copying designs back to Figma goes through the clipboard. Worktree chats open a GitHub pull request through the GitHub CLI when it is signed in, or push the branch and open GitHub's compare page. The agent calls external MCP servers over stdio, SSE or streamable HTTP with custom headers, static OAuth or dynamic client registration, with each tool switchable, indexes npm packages and Storybook from a Git address using the workspace's credentials, and runs terminal commands on its own. No native Jira or Slack connector exists. Sourcedocs.kombai.com/features/mcp/external-mcp-servers.mdread 2026-11-08 |

| Workflow Orchestration | Full |
|
Several agents run at once, in one canvas or many, and in the desktop app each chat can take its own Git worktree on a separate branch so parallel tasks do not collide. The default agent keeps a todo list as it works, Plan mode writes an editable plan file before any code, and Debug mode proposes a plan and applies it only after approval. Context Graph builds split their analysis across parallel subagents, a background tasks panel tracks work in progress, and a canvas node can be locked while an agent edits it.

Context Graphs index the components, hooks, stores, design tokens, types and constants in the workspace, in npm packages and, on the Team plan, in Storybook, built by dedicated subagents and kept between sessions until someone rebuilds them from Settings. A ContextRules file steers what counts as reusable, and graphs sync to a stack file so teammates pick them up. Design systems persist as files Kombai builds from a codebase, a Figma file, a live website or a canvas design, a Component Library draws indexed components in up to eight states, and curated retrieval covers more than 400 frontend libraries. Where the index is stored is not stated. Sourcedocs.kombai.com/context/context-graphs.mdread 2026-11-08 |

Plan mode stops for Approve and Code or Approve and Design before anything is written, and checkpoints restore the code, the conversation or both. Terminal commands run under one of three settings: Ask Every Time, Auto approve for me, where a classifier decides and which is the default, or Bypass permissions. Every change appears as a diff in the Changes panel, edits made by terminal commands can be undone, merging goes through a pull request, and closing a worktree asks whether to keep or remove it. The agent may use the browser unless a setting turns that off. Sourcedocs.kombai.com/features/terminal.mdread 2026-11-08 |

Kombai's trust center lists SOC 2 as compliant without naming Type I or Type II or a report date, alongside encryption at rest and in transit and six named subprocessors including AWS. Single sign on with SAML, audit logs, custom retention and a DPA sit in the Enterprise column of the pricing table with no setup guide, while Team plans get three roles: Team Admin, Team Member and Billing Admin. Every plan promises no AI training on customer data, though the terms give Kombai a perpetual license to aggregated data drawn from customer data. Sourcekombai.trust.siteread 2026-11-08 |

| Observability & Auditability | Partial |

Credit logs record daily, rollover, purchased and expired credits, each chat shows the credits it used, and an Outputs card counts the files added and removed. Team admins see usage per member per day in near real time, but that view has no export and credit usage alerts are not yet available. Audit logs appear only as an Enterprise line on the pricing table, and no run trace, tool call log export or telemetry feed is offered for what the agent did.

| Memory & State Persistence | Full |
|
Agent Memory records what the agent learns about a project automatically and keeps it as Markdown files in the user's Kombai folder with an index file, turned on by default. Users can view, edit and delete each memory, which gives a purge path, though no expiry is set and no team or global scope is described. Rules at project, user and team scope, AGENTS files, skills and commands carry standing instructions alongside memory, and rules survive when long chats are compacted.

| Deployment & Data Residency | Partial |
|
The desktop app runs on macOS, Windows and Linux, and its agents work on the developer's own machine against the local repository, with Design mode also working over Remote SSH. Local agents can run on the developer's own Claude Code or Codex subscription, though Kombai credits still apply to MCP calls. Kombai's own models, credits and hosted canvases run through its cloud service on AWS, and no hosting region, private cloud, VPC or self hosted edition is offered.

Kombai ships ready modes for design, planning, read only questions and debugging next to its default agent, plus frontend skills for improving a UI, accessibility and SEO audits, wireframes, themes, cloning a page from its address and generating images and video. A gallery of more than 20,000 designs, an Inspiration Library of templates and public design systems modeled on brands such as Discord, Stripe and Nike give teams starting points they can build from in their own stack.

Work starts from a chat in the desktop app or the editor extension, from slash commands and skills, or from Send to agent in the in app browser and the browser extension. Other agents can start Kombai work too, through the Kombai MCP server set up for VS Code, Cursor, Claude Code, Codex, Antigravity and Gemini CLI and through plugins for Codex, Claude Code, ChatGPT Desktop and Claude Desktop. Nothing starts a run on a schedule, from a webhook, from a repository or tracker event, or from a standalone command line or public API.

| Model Flexibility & Routing | Full |
|
Each chat picks one of 32 language models from 12 providers or the Auto router, which can change model on every turn, and models draw credits at multipliers from 0.03 to 5 times, with Auto between 0.1 and 1 times. Eight image models and 15 video models handle asset generation. Local agents can hand work to the developer's own Claude Code or Codex, but there are no bring your own API keys, and admins have no control over which models a team may use.

The Kombai MCP server runs locally while the desktop app is open, showing a running badge and port, and writes its entry into the configuration of each client it supports. Kombai names no endpoint, no auth scheme and no list of MCP tools, giving only the skills it installs, such as designing, coding a design and improving or reviewing UI, and a recent release installs a lightweight skill in place of a full server entry. Plugins for Codex, Claude Code, ChatGPT Desktop and Claude Desktop sign in through the browser, and no public REST API or SDK exists.

| Testing, Debugging & Optimization | Partial |
|
The agent runs the project's own lint and build checks after it writes code, and its browser tools add accessibility and SEO audits and Core Web Vitals readings for the pages it changed. Debug mode confirms a fix through the browser or the user's feedback, and the Improve UI skill closes with a verify stage. Kombai writes and runs no test suite of its own, no quality gate blocks a merge, and its Design Creativity Bench rates Kombai itself rather than the customer's output.

| Browser / Computer-use | Full |
|
In the desktop app the agent drives an in app browser by default or a Chrome window, and in the editor extension it always uses Chrome. It navigates, clicks, types, fills forms and scrolls through pages, with a separate browser session for each chat, and on macOS it can import cookies from a Chrome profile. The editable browser lets people change a page visually while Kombai turns those edits into code in the repository, so a visual tweak ends as a reviewable change.

Pricing
Free with 300 credits a month, or Pro at $20 a month for 2,000 credits, $16 a month billed yearly.
Plans sized by monthly credits and billed monthly, quarterly or yearly, with a shared credit pool and a per seat charge on Team, plus one time credit packs.
Included quota
Pro includes 2,000 credits a month with rollovers up to five times the monthly amount, larger Pro tiers run up to 110,000 credits, and Team adds unlimited rollovers in a pool shared by all members.
What is public
Free and Pro tiers with monthly and yearly prices, Team pricing per seat, credit pack prices and model credit multipliers, with Enterprise by contact.
Billing mechanics
Credit based plans billed monthly, quarterly or yearly with 20% off yearly, model multipliers on credit use and one time credit packs.
Cost watchouts
Premium models draw up to five times the base credit rate, MCP calls from local agents still use Kombai credits, and free credit rollovers stop at half a month's allowance.
Variable cost rationale
Plans are flat prices for a monthly credit allowance, but each model draws credits at its own multiplier from 0.03 to 5 times, so how much work a plan covers depends on model choice, and heavy users move to larger tiers or buy credit packs.
Additional watchouts
Credit use varies widely by model, and the Team seat cap differs between the pricing page and the docs.
Overage / add-ons
Extra credits come from one time packs at $11 for 1,000 or $110 for 10,000, or from moving to a larger credit tier; models draw credits at 0.03 to 5 times the base rate.
Sales call required
Mixed (some tiers require a call)
Free / trial
The free plan includes 300 credits a month with parallel agents and the full design and code flow, and unused credits roll over up to half a month's allowance.
Lowest paid plan
Pro at $20 a month
Commercial notes
Kombai, Inc. sells directly through its website, with the desktop app and editor extensions on one account.
Key ambiguities
The pricing page caps Team at 20 seats while the docs FAQ says up to 100 members, free credit wording differs between the pricing page and the docs, and the docs pricing page leaves out the Team plan.
Cancellation / refund
Monthly, quarterly or yearly self serve plans; Enterprise by contract.
Support SLA / resale
Pro adds email support, Team adds centralized billing, shared rules and commands and usage analytics, and Enterprise adds dedicated support, onboarding services, custom SLAs, single sign on with SAML and audit logs.
Missing data
Enterprise pricing, the exact Team seat cap and how credits map to typical tasks.
