Hosting for AI-made sites and apps.
Build websites with your AI.
Works with any AI
AI can now make almost anything you can describe. A website for your bakery, slides for Monday’s meeting, a birthday invitation, a small game for your kids. The tricky part comes after, when you want to get it out of the chat and in front of people.
That’s what Spacefast is for. Ask your AI to put it on Spacefast and you’ll get a private address. Create a share link or make the Space public before sending it to anyone, whether it’s a whole website or this week’s lunch menu.
Tell Claude, ChatGPT, or any other AI to use Spacefast, and you’ll get a link back right in the chat. Keep making changes whenever you like, and anyone with the share link will see them.Publish supported Next.js, TanStack Start, Astro, and PHP projects. Runtime features depend on the deployment path, so check the guides before your AI starts.
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.space.fast.
Each thing you make gets its own Space. Create a share link or make it public before sending it to anyone. No account needed to get started.
A chat window where Maria asks for a deck and a live Spacefast link arrives, with a claim card counting down its expiry.
Spaces are private by default, so nothing goes public by accident. Invite a few people, share a private link, or make it public whenever you’re ready.
A Sharing panel where Private is switched on, four people are invited, and public link access is off.
Try things without worrying. Each change saves a version, so you can always go back to one you liked more.
A Version History window listing kept versions: Live now, Before Maria’s edits with a Restore button, Chart swapped, First publish.
Turn on comments to hear what people think, right where it applies. Take care of them yourself, or let your AI handle it.
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.

Every space comes with a MySQL-compatible database. 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.
Drag a folder or zip onto drop.fast. No terminal, no account.
A browser window at drop.fast with a dashed drop zone, and a zip file being dropped onto it.
Connect a repo at git.spacefast.com. Pushes to main go live, and other branches get preview links.
A browser window at git.spacefast.com listing branches: main publishing to production, a feature branch getting a preview link.
One command from any terminal. Rollback, sharing, and domains are scriptable too.

Ask your AI to publish with Spacefast. It replies with a live address. New spaces are private, so create a viewer link before you share it.
No. Publish without one and you get a live address plus a private claim link. Sign up when you want to keep the space.
Static HTML, presentations, games, and apps built through supported Next.js, Astro, or TanStack Start paths. Check the framework guides for runtime requirements.
Yes. Ask your AI to publish again and the same link updates. Each change saves a version, and you can roll back to any version still in your history.
New spaces are private: the URL alone doesn’t grant access. Invite people, create a share link that works for anyone holding it, or make the space public. Search indexing is a separate setting.
Download the files from any retained version. Static sites usually move to another host as they are. Apps on Spacefast runtimes need code changes, and app data exports separately.
Claimed spaces stay live until you unpublish them, at the same address as you publish changes. Unclaimed Spaces normally expire 33 hours and 20 minutes after creation or the latest publish that changes files, capped at 30 days from creation. Claim the Space to remove anonymous expiry. Retained versions follow the plan’s history policy.
