Free workspaces can now choose link sharing for each file. Anyone with the share link can view the file without signing in to Artifact Share. Expiration works the same as on Plus: new workspaces default to 30 days with no maximum. Existing workspaces keep their saved expiration settings, and changing plans does not rewrite them.
In the browser, choose "Anyone with the link" in the who-can-view dialog. In the CLI, pass --visibility link; in MCP, set visibility to link.
Teams post files to a shared project but only the people who go check the project notice new work. Sharing a link manually in Slack every time is easy to forget.
A project can now be linked to one Slack channel. Start from Project detail → "…" menu → "Slack notification", and pick the channel on Slack's own authorization screen. Any channel you belong to works, including private ones. When a new file is posted to a linked project, the channel gets an automatic message with the title, uploader, and link. Multiple uploads posted in a short window are combined into a single message.
Artifact Share CLI 0.8.2’s artifactshare append <target> <path> and remote MCP’s append_artifact append content to a single shared file and create a new version at the same share link. For Markdown, they append to the end of the current source. For HTML, they append immediately before the closing body tag when present, or at the end otherwise. Neither adds a newline or separator.
If another update lands first, the operation preserves it and returns version_conflict with the current version ID. Run the operation again to append to the latest version. Static sites are not supported. To replace the full source, use CLI update or MCP update_artifact.
