Anthropic Makes Claude Artifacts Multiplayer so Teams Can Build Together

Anthropic just shipped a meaningful upgrade to how teams work with Claude Artifacts. The headline: Artifacts are now multiplayer. Multiple people can edit the same artifact at the same time, public sharing via link is now live, and Claude Tag can generate internal artifacts directly from a Slack thread. Together, these changes push Artifacts from a personal prototyping tool into something that looks a lot more like a shared product surface.

What just changed

Three things landed in this update:

• Multiplayer editing -- by default, artifacts in Claude Code are only visible to the individual who created them, but they can now choose to share artifacts with the rest of their organization. The new multiplayer mode lets multiple teammates edit the same artifact simultaneously, without passing file versions around.
• Public sharing -- publishing makes an artifact publicly available, and anyone with the link can view and interact with it. Recipients do not need a Claude account to view published artifacts, and users with an account can remix them -- creating their own editable copy.
• Claude Tag can now build internal artifacts -- ask for a dashboard in a Slack thread and Claude Tag returns a working, shareable page scoped to your organization.

The plan split you need to know

Not everything is available everywhere. The access model is a bit layered:

• Multiplayer editing: Team and Enterprise plans only.
• Public sharing (Publish): available on Free, Pro, and Max plans -- makes an artifact publicly available and anyone with the link can view and interact with it.
• Org-scoped sharing (Share): Team and Enterprise only -- makes the artifact available within your organization, with viewers required to be logged into your Team or Enterprise account.
