Don’t add another AI agent to your stack.
Hexby works with the agents you already trust — including Claude Code, Codex and Cursor. Hexby provides the visual interface and workflow. Your existing agents do the AI work underneath.
Instead of throwing design files over the wall to engineering, Hexby lets you design directly on your actual coded product.

Why Hexby?
Figma
Design lives outside the product.
You can design exactly what you want, but it's disconnected from the code that ships.
The gap
Designs aren't connected to the code that actually ships.
AI coding agents
Make coding easier. Leave design behind.
Agents can change your code, but you only see the result in prompts, code, or a running app.
The gap
Code changes, but there's no easy way to work with just the UI
Hexby
Design on the real UI with your agents.
Connect your codebase, visualize the real UI, and change it with the agents you already use.
The solution
Your codebase becomes the actual visual design environment.
Your code. Your agents. Your UI.
How it works
See what’s actually shipping. Change it visually.
Let your agents do the work.

The codebase Hexby opened — the source of every screen on the canvas.

The same UI, laid out as a canvas of the screens the code actually renders.

Your existing agent does the AI work, pointed at the thing you selected.

Submit for review. Nothing reaches the repository until somebody means it to.
Your codebase
Instead of designing against screenshots or maintaining another artifact that drifts from production, Hexby gives your team a visual workspace on top of the code that actually runs your product.
Codebase to Hexby Canvas to Codebase.

Hexby doesn’t replace the codebase. It makes it visual.
The workspace
Explore the workspace views, starting with Pages and the components they use.
All Components
Every component you have on one free canvas, with project-wide search, filtering by kind and sorting. Zoom in and the cards become the real components, live and clickable, so you can hover them and try their states without leaving the canvas.

Pages
Pick a page and the canvas draws it together with its whole dependency closure. A shared component appears under every parent that uses it but resolves to one record, so before you change anything you can see everywhere it would land.

Component Map
Hexby reads your project and lays out every page, layout and component as a map, connected by what actually renders what. The layout is deterministic, so the same project always draws the same map and you can learn where things live.
Zoom out to take in the shape of the whole project. Zoom in and every node shows the screen it renders, named, with the kind it is. Files you have changed pick up a git status border, so the map doubles as a picture of your work in progress.

Component View
Isolates a single component in the middle of the canvas with Desktop, Tablet and Mobile breakpoints, and a resizable code dock below it showing that component's source. When the component has a companion stylesheet, the dock splits so you can see the markup and the styles together.

Preview App
Hexby starts your project's own dev server and frames the running app, with an address bar that drives its real history, route autocomplete from the analysis, and Desktop, Tablet and Mobile viewports.
The Inspect dock is where someone who does not write code gets to work: a live layers tree, controls for colour, typography, spacing and layout, and a Content tab for editing the words on the screen.

Review
A live before and after comparison, both sides rendered from your own code. It reads your local git history, so opening a review is instant. Compare against the branch baseline or against the last version you sent.
When it is right, share the link. Teammates review it in the browser with nothing to install, and their feedback comes back pinned to the component it is about, so you reply and resolve it in the same panel.

Handoff / Submit to Devs
When everyone is happy, hand it off to developers. Hexby opens the pull request with the before and after attached, so the visual work lands in the same review and merge workflow you already use.

Chat
Ask your agent to build, edit, or refine your components. Select something on the canvas and it comes along as context, so the agent knows exactly which file you mean. Paste an image, run a slash command, or dictate.
Answers come back as plans, diffs and permission cards you approve. Nothing is written to your project without you saying yes.

Show your agent exactly what to change. Send it all in one go.

Review before merge
Move fast without letting non-developer changes go straight to production.
Select elements, make changes, and see the results instantly on your actual codebase components.

Annotate the live preview. Reviewers see the same components the code renders, so feedback lands on the thing that ships.

Designers send real components for review. Approved work is ready to hand off.



Submit the visual work as a review round. Nothing reaches the repository until somebody means it to.



The visual review posts into the pull request—what changed, what was approved, and a link to open it. Developers stay in GitHub.

Changes go live to production.

Hexby gives designers and product teams a way to work close to production while keeping your existing review and merge workflows intact.
Built for modern teams
Whether your app was built by a senior engineer, an AI coding agent, or somewhere in between, Hexby lets you bring the UI into a visual workspace and keep iterating.
