Claude Code Warns That Standalone Claude Design Closes by December 14, 2026

Claude CodeView original changelog

Claude Code 2.1.302 adds a notice to the /design-sync and /design-login commands stating that standalone Claude Design, the web app at claude.ai/design, closes by December 14, 2026. The warning reaches users through the two commands that connect the CLI to the design tool, so anyone who relies on that workflow learns the end date from inside their terminal.

Key Takeaways

  • Standalone Claude Design at claude.ai/design closes by December 14, 2026, per a notice added in Claude Code 2.1.302.
  • The warning is delivered inside the CLI, in the /design-sync and /design-login commands that connect Claude Code to the tool.
  • The word "standalone" is doing work: it points at the separate web app, not at Claude's design capability in every surface.
  • Claude Design launched in April 2026 and gained its terminal integration in June 2026, so this closes a roughly eight-month-old product destination.
  • The changelog entry does not state a migration path or say what happens to existing design files.
  • Users who start their workflow at claude.ai/design have roughly two months of notice to plan around it.

A closing date delivered through the CLI

Claude Code 2.1.302, published on October 16, 2026, adds a notice to /design-sync and /design-login telling users that standalone Claude Design — the web app at claude.ai/design — closes by December 14, 2026.

The placement is the notable part. Rather than a banner on a marketing page, the warning sits in the two commands that actually connect the terminal to Claude Design: /design-login, which authorizes the connection, and /design-sync, which pulls a design into the working session. Anyone still using that workflow will see the date the next time they run either command.

What is closing

The wording is specific: it is standalone Claude Design that closes. Claude Design launched in April 2026 as Anthropic's visual design tool with a design-to-code handoff, and gained a terminal integration through /design-sync in June 2026. The "standalone" qualifier points at the separate web destination at claude.ai/design rather than at design capability everywhere it appears — in September 2026 Claude Code gained the ability to work with Claude Design artifacts from any conversation, which is a different surface.

Anthropic did not publish a migration path in the changelog entry itself, so what replaces the standalone app for existing users is not stated there.

Who should act

Anyone whose workflow starts at claude.ai/design has about two months of notice. The practical questions — where existing design files live after the closure, and whether /design-sync keeps working against a different destination — are not answered by the changelog bullet, which gives the date and nothing more.
