Question 1

What is Prototyper?

Accepted Answer

Prototyper is a design canvas where AI agents build real, working apps. You describe what you want, an agent writes actual React code, and the result runs live on the canvas where you can edit it, branch it, and ship it. The design is the code, so there's no handoff stage: the prototype is the product.

Question 2

How is Prototyper different from Figma or Framer?

Accepted Answer

Figma and Framer give you mockups someone has to rebuild. Prototyper gives you the actual product. The design IS the code, same artifact, same canvas, no handoff stage. The prototype is the product.

Question 3

How is Prototyper different from v0, Lovable, or Bolt?

Accepted Answer

Those tools are chat-first: you prompt in a text box and results replace each other in a transcript. Prototyper is canvas-first: versions sit side by side, you steer by pointing at things, and you edit the result directly like a design tool. And instead of paying per generation, you can bring the agent subscription you already have.

Question 4

Do I need to know how to code?

Accepted Answer

No. You describe what you want and the agent writes the code. What matters is knowing what you want the interface to do and reacting to what appears on the canvas. If you do write code, everything is real React you can open and edit by hand.

Question 5

How do I get started?

Accepted Answer

Sign up free, open a workspace, and describe your first screen. There's no setup step: the built-in agents work immediately, and you can connect your own agent whenever you like.

Question 6

Can I bring my own AI agent?

Accepted Answer

Yes. Bring the Claude Code or Codex subscription you already pay for and use it on the canvas. Your agent does the generating, so you're not buying AI usage twice.

Question 7

Which agents work with Prototyper?

Accepted Answer

Claude Code, Codex, Cursor, Copilot, and any other agent that speaks MCP. Prototyper also ships with built-in agents, so you can start without connecting anything.

Question 8

How do I connect my agent to Prototyper?

Accepted Answer

Mount Prototyper as an MCP server in your agent's configuration. Once connected, your agent gets the full workspace toolset: it reads your files, builds on the canvas, and everything it does shows up live for you and your team.

Question 9

Do I have to connect an external agent?

Accepted Answer

No. The built-in agents work out of the box on every plan. Connecting your own agent is worthwhile when you iterate heavily, because generation then rides on the flat-rate plan you already pay for.

Question 10

Is Prototyper free to use?

Accepted Answer

Yes. The Free plan is free forever and doesn't ask for a credit card; there's no trial that expires. Paid plans add export, collaboration, and advanced features when you're ready.

Question 11

What do the paid plans cost?

Accepted Answer

Premium is $20/month ($16/month billed annually). Team is $30 per editor seat/month ($24 annually) with AI credits pooled across the team; viewers are always free. Team Business is $100 per seat/month ($80 annually) for orgs that need more pooled credit and controls.

Question 12

Can I cancel, upgrade, or downgrade at any time?

Accepted Answer

Yes. You can change or cancel your plan whenever you like from your account's billing settings, and your invoices live there too. If you cancel, you keep the Free plan and your work stays yours.

Question 13

What payment methods do you accept?

Accepted Answer

Payments run through Stripe, so all major credit and debit cards are accepted.

Question 14

Do I own the code I create?

Accepted Answer

Yes, 100%. Everything you build and export is yours: no licensing restrictions, no attribution requirements. Ship it, sell it, or open-source it.

Question 15

How do I download my work?

Accepted Answer

Export it from your workspace as real React code. There's no proprietary format in the way: what you designed on the canvas is the code you take with you. Export is included on paid plans.

Question 16

Is there a desktop app to download?

Accepted Answer

No download needed: Prototyper runs in your browser. Your workspaces are saved to your account, so you can pick up where you left off from any machine.

Question 17

Can I use the exported code in my existing codebase?

Accepted Answer

Yes. Exports are standard React and Tailwind with a component structure that mirrors what you built, so you can drop individual components into an existing project rather than adopting a monolith.

Question 18

Can my team work in the same workspace?

Accepted Answer

Yes. The canvas is multiplayer: teammates see each other's cursors and changes live, and agents work on the same surface alongside everyone. The Team plan covers editor seats, and viewers are always free.

Question 19

How do I share a prototype?

Accepted Answer

Send the link. A link is a workspace, so whoever opens it sees the real, running thing rather than a screenshot. You choose whether they can view or edit.
