Works with any AI tool

What you're joining the line forOne link does the whole job

The link

One message hands you a live link. Publish first, sign up later. Claim it within 6 hours and it's yours, same link forever.

A chat window where Maria's message hands over a live spacefast.com link, with a claim card counting down its six hours.

History

Every change is a kept version. Roll back in one step, or take the whole thing to your own domain.

A Version History window listing kept versions: Live now, Before Maria's edits with a Restore button, Chart swapped, First publish.

Access

Private by default. Invite people, hand out visitor links, or make it public when you choose.

A Sharing panel where Private is switched on, four people are invited, and public link access is off.

Comments

Comments pin to the exact spot. Reply, resolve, and the thread keeps its context.

A published page where a comment from Maria is pinned to the exact bar of a chart, beside a chat thread confirming you can leave comments in the project itself.

However you work, it ships

A Mac desktop: ChatGPT showing a finished conversation that published a page, Claude publishing another one and answering with the live link, and a notification confirming the page is live at mellow-fox.spacefast.com.

From a chat with Claude or ChatGPT, from your terminal with npx spacefast publish, from a push to GitHub, or from a folder you drag. Every route ends at the same link.

Batteries included

A real MySQL-compatible database is built into every space. The space's dashboard open on its Database page: a users table with eight rows of names, emails and roles, and row counts for the orders and sessions tables beside it.

Publish however you like

Drop

Drag a folder or a zip onto drop.website and it publishes as it lands. No terminal, no account.

A browser window at drop.website with a dashed drop zone, and a zip file being dropped onto it.

Git

Connect a repo at push.new and every push publishes: main goes to production, branches get preview links.

A browser window at push.new listing branches: main publishing to production, a feature branch getting a preview link.

CLI

One command from any terminal. Versions, rollback, sharing and domains live there too, scriptable end to end.

A terminal running npx spacefast publish and replying: Live at quiet-sun.spacefast.com.

Frequently asked questions

When will I get an invite?

We are sending out invites every day. If you have cool ideas and want to skip the line, .

Can I move an existing site?

Yes. Most sites currently deployed on popular platforms can be moved over with no code or configuration changes.

What can I put on it?

Anything that runs on the web. From a single HTML page for presentations, research, games, to frameworks like Next.js, Astro, TanStack Start and more.

Which AI tools does it work with?

Any of them. Claude, Claude Code, ChatGPT, Cursor and VS Code are the ones people reach for most, but nothing about Spacefast is specific to a single tool.

What does it cost?

Start free with unlimited cached traffic, 10 GB storage and 3 custom domains. Upgrade to Plus for $4.99/month for more storage and increased limits.

Who can see what I publish?

Only the people you send the link to. Everything is private by default, not listed anywhere, not indexed, until you make it public.

How long does my link stay live?

Until you decide otherwise. Spaces do not expire for inactivity and versions stay republishable. Ask your agent to unpublish and the link stops working straight away.

Who's behind this?

Automattic, we are the folks behind WordPress.com, WooCommerce, Pocket Casts, Tumblr, Day One, Gravatar, and much more. We've been around for over two decades focused on making the web a better place.

How do I publish a page?

Tell your agent to publish it with Spacefast. It hands back a link you can send to anyone, in the conversation you were already having. No dashboard to open, nothing to configure.

Do I need an account?

No. The first publish sets up everything it needs, so you can go from a conversation to a live link without signing up for anything.

What can I publish?

Only the people you send the link to. Everything is private by default, not listed anywhere, not indexed, until you make it public.

Can I take everything and leave?

Yes, by design. One command downloads every file of any version to a folder you can host anywhere. Staying should be a choice you keep making, not a lock you discover.
