Claude Design alternatives when your agent is Codex, ChatGPT, or Cursor

What Claude Design does

Anthropic says that Claude Design "lets you create designs, interactive prototypes, one-pagers, and other visual work by chatting with Claude". It is on each Claude plan. It exports a .zip, PDF, PPTX, Google Slides, and standalone HTML.¹

The standalone version at claude.ai/design closes on 14 December 2026. Claude Design continues as a template in Claude.¹

Why people look for an alternative

• The AI is Claude. A person on Codex, ChatGPT, or Cursor cannot use that agent in Claude Design.
• Anthropic says that editing by two or more people "is still basic and may not work reliably".
• The standalone site closes, so teams that used it look at their options.¹

If your agent is ChatGPT

ChatGPT Sites makes a designed page from a prompt, on the Plus, Pro, Business, and Enterprise plans. You change a Site by prompt: "Ask ChatGPT for changes until the Site looks and works the way you want." There is no canvas to move an element by hand.²

If your agent is Codex or Cursor

A coding agent writes a designed page as HTML. The result can be as good as a design tool makes, because the agent controls each line. The page is then a file on your computer, with no link, no editor for other people, and no versions.

If the team uses more than one agent

Use a place that each agent can write to. Sunday is made for this: Claude, ChatGPT, Codex, and Cursor connect through MCP and make a free-form page. Each person changes each part by hand, on the same page as the agent. A share link opens the page with no account. Sunday is in private beta.

What you give up

• The design system setup of Claude Design for an organization.
• Export to PPTX and Google Slides in one step.
• A product that is open today. Sunday is in private beta.¹
