Automattic launched Spacefast on November 9 as a place to host apps and websites built with an AI agent. According to Automattic's announcement, a builder can keep working in their usual assistant, ask it to publish a project and receive a link to review. Hosting and database setup sit with Spacefast rather than requiring a move to another AI builder.
What comes with the launch?
Spacefast provides hosting, a domain and a SQL database. It creates a new version on each publish and gives each version a permanent URL. A team can link to an older build or roll back. The version history gives a reviewer a specific version to comment on instead of relying on a preview that changes as work continues.
The default is private sharing. Automattic says a team can share through a password, invite or share link, or open the app to the public. It also describes page comments so collaborators can leave feedback for the next revision.
How do agents connect?
Automattic lists an API, a command-line interface and an MCP server. The announcement names assistants including Claude and ChatGPT and coding agents such as Codex and Cursor. Spacefast provides tool descriptions so the agent can ask for resources like a database during a project. The company says sensitive actions such as changing DNS or rolling back a version require approval.
What still needs a separate decision?
The announcement says built-in app authentication is coming later. A private preview with limited sharing is useful for reviewing a build, but it does not supply a signed-in experience for the eventual app's users. For a project that needs accounts at launch, a builder should confirm how that piece will work before moving beyond the preview.
