Prototyper vs Claude Design
Claude Design is Anthropic’s design tool inside Claude: you chat, and Claude produces designs, prototypes and slides you can edit, export and hand to Claude Code. Prototyper is an independent canvas where the agent you already use, Claude Code included, builds running React apps over MCP, next to your team and its briefs.

“Claude design” used to mean designing interfaces with Claude in a chat window. Since 17 April 2026 it also names a product: Claude Design, from Anthropic Labs. If you are weighing it against other tools, this page sets out where it is strong, where Prototyper differs, and how the two fit together. Both lean on Claude. The difference is where the work lives and which agent does it.
What Claude Design is
Anthropic launched Claude Design on 17 April 2026 as a research preview powered by Claude Opus 4.7. It makes polished visual work: designs, interactive prototypes, slides, one-pagers and more. You start from a prompt, uploaded images and documents, or your codebase. You refine the result by chatting, commenting inline on an element, editing text directly, or moving the adjustment sliders Claude generates.
It reads your codebase and design files to build a design system, and later projects use it automatically. Finished work exports to PDF, PPTX, standalone HTML or a .zip, goes to integrations such as Canva and Miro, or travels to Claude Code as a handoff bundle. Since the 16 September 2026 release, it also works inside ordinary Claude conversations, the Artifacts tab, and Claude Code through its /design command, as well as at claude.ai/design.
Prototyper and Claude Design side by side, as of 2026-10-06
A fair comparison, not a scorecard. The Claude Design column sums up Anthropic's help article and product page; the Prototyper column describes our own product.
| Prototyper | Claude Design | |
|---|---|---|
| Made by | Prototyper, an independent company | Anthropic (Anthropic Labs) |
| Who does the work | Your agent: Claude Code, Codex, Cursor or another MCP client | Claude, inside Claude |
| Where you work | A shared infinite canvas in the browser | Claude conversations, the Artifacts tab, Claude Code, claude.ai/design |
| What it makes | Running React and Tailwind apps, wireframes and slide decks | Designs, interactive prototypes, slides and one-pagers |
| Steering | Point, select, leave a sticky, or prompt your agent | Chat, inline comments, direct edits, adjustment sliders |
| Getting work out | Export the real file tree through your agent (paid plans) | PDF, PPTX, HTML, .zip, integrations, Claude Code handoff |
| Sharing | Multiplayer canvas; viewers are always free | Private by default; share with view, comment or edit access |
| Usage | Building runs on your own agent subscription | Counts toward the same usage limits as the rest of Claude |
When to pick Claude Design
Pick Claude Design when your team already lives in Claude and wants design there too, with no new tool to adopt. Anthropic offers it on its Pro, Max, Team and Enterprise plans, and organization admins control whether it is turned on.
It is the stronger choice when the output is presentation work. Slides and one-pagers are first-class, and exports to PPTX, PDF and Canva put the result straight into the tools a sales or marketing team already uses.
It also suits teams that want one approved design system enforced everywhere: admins can lock a team to it. And when a design is ready to build, the handoff bundle to Claude Code keeps the whole path inside Anthropic's products.
When to pick Prototyper
Pick Prototyper when the design should be the product: a running React app that people click, type into and resize, not a picture of one. On the canvas, the code your agent writes is the code you take toward production, the same pipeline described on our AI prototyping tool page. For an earlier pass, the AI wireframe generator sketches at least three hand-drawn options and builds the one you pick.
Pick it when your team does not run on one agent. Claude Code, Codex, Cursor and other MCP clients all connect the same way, and several agents can work on one surface. Building runs on the subscriptions you already pay for, so it does not count against a design tool's allowance.
And pick it when design is a room, not a document. Briefs, sketches, stickies and several directions sit side by side on an infinite canvas, and your whole team, viewers included, works on the running screens.
Bring your own Claude: how Claude Code drives the canvas
Prototyper runs an MCP server, so Claude Code (or any MCP client) can work in your workspace directly.
- 01
Connect in one command.
Run “claude mcp add --transport http prototyper https://www.prototyper.co/api/mcp” in your terminal, then approve the authorization prompt. The connect your agent guide covers Codex and other clients.
- 02
Claude reads the room.
Your notes, references and sketches are already on the canvas. Claude reads them through the workspace file system, so the brief does not have to be re-typed into a prompt.
- 03
The design arrives running.
Claude writes files with MCP tools such as vfs_write and vfs_patch, builds them with app_build, and the app runs in a window with a live preview.
- 04
Steer by pointing.
Select the header that feels wrong, or leave a sticky on the empty state. Claude sees the same surface you do, so “this one, smaller” works as an instruction.
Use both
The two are not exclusive, and both meet in Claude Code. A team can use Claude Design for the pitch deck and the one-pager, and the canvas for the product those slides describe. Claude Code is the bridge: it receives Claude Design's handoff bundle, and the same session can connect to Prototyper over MCP and build that design as a running app on the canvas, where the rest of the team can review it.

Frequently asked questions
- What is Claude Design?
- An Anthropic Labs product, launched on 17 April 2026, that lets you create designs, interactive prototypes, slides and one-pagers by chatting with Claude, then refine them on a canvas with comments, direct edits and sliders.
- Is Prototyper a Claude Design alternative?
- For interface work, yes. Prototyper is an independent canvas where your own agent, such as Claude Code, Codex or Cursor, builds running React apps. For slides and one-pagers, Claude Design is the more direct fit.
- Can I use Claude with Prototyper?
- Yes. Prototyper runs an MCP server, so Claude Code connects with one command and builds on the canvas on the Claude subscription you already pay for. Other MCP clients connect the same way.
- Can I use Claude Design and Prototyper together?
- Yes. Claude Design can hand a design to Claude Code as a bundle, and Claude Code can connect to Prototyper over MCP to build it as a running app your team can review on the canvas.
- Is Prototyper affiliated with Anthropic?
- No. Prototyper is an independent product that works with Claude through MCP, an open protocol. Claude and Claude Design are trademarks of Anthropic, and we are not affiliated with or endorsed by them.
