A home for what agents make.

Spacefast turns the useful thing at the end of a chat into something people can open, share, revisit, and keep.

Built for the handoff

People make pages, prototypes, reports, visualizations, and small apps with agents every day. Too often the result stays trapped in a local folder or a conversation. Spacefast closes that last mile: publish the files, get a live URL, and send it to the person who needs it.

A space is the durable home for that work. Each publish creates an immutable version with its own address. The live address can move forward or roll back without rebuilding. Access starts private, then widens only when you choose who should see it.

Spacefast is made by Automattic, the company behind WordPress.com, WooCommerce, Tumblr, Jetpack, Day One, Pocket Casts, and Beeper. It brings that long-running web infrastructure to the smaller, faster things people now make with agents.

What stays true

The result should outlive the chat

A useful page should not disappear when a conversation ends. Spacefast keeps its address through revisions and lets you restore a retained version when an update goes wrong.

Sharing should be the easy part

Agents are good at making things. They still need a simple way to hand the result to a person. Spacefast turns files into a live URL, then adds private access, feedback, domains, and rollback when the work needs them.

Agents get the same product

The dashboard, CLI, API, and MCP server are different doors into the same spaces and versions. An agent can publish and manage the work without asking a person to repeat every click.
