Your questions, answered straight.

The short, useful version: what Spacefast is, what it costs, and what happens at the edges. Spacefast is in research preview.

The basics

What is Spacefast?

Where the things your agent makes go to live. Publish a folder, choose who can open it, and keep updating the same address. Claim an anonymous space to remove its expiry deadline.

When will I get an invite?

We send invites every day. Have something cool to publish? Get in touch to skip the line.

What can I put on it?

Static HTML, presentations, games, and apps built through supported Next.js, Astro, or TanStack Start paths. Check the framework guides for runtime requirements.

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.

The product

Can I move an existing site?

Static sites can usually move with no code changes. Spacefast reads Netlify-compatible redirect and header files, and connected builds detect common frameworks.

How fast is a publish live?

A new version is usually live within ten seconds of the upload finishing. There is no build queue and no pipeline to configure. Spacefast serves your files as they are.

Keeping it yours

How long does my link stay live?

Claimed spaces do not expire for inactivity. The live address stays the same as you publish changes. Free spaces have a history limit, so older versions that are no longer served can expire. If you unpublish, the live link stops serving.

Who can see what I publish?

New spaces start Private: a bare URL does not grant access. Invite specific people, create a scoped share link that anyone holding it can use, or choose Public. Search indexing is a separate choice for public pages.

Can I take everything and leave?

You can download files from retained versions. A static site can usually move to another host with those files. Apps using Spacefast runtimes need code changes, and app data has a separate export path.

Plans and billing

What does it cost?

Free is for personal, non-commercial projects. Go is $5 a month with $5 of usage credit. Plus is $15 with $15 of credit and 10 editors. Plans are billed monthly. These are our upcoming plans. Check Settings → Billing for the plans currently available to your team.

What exactly does Free include?

Free includes 20 Spaces, 20 custom domains, 500 MB of storage and 100 GB of cached delivery a month for one editor. Compute, builds, email and Workers have separate allowances. No card required. Personal and non-commercial use only.

What do the paid plans add?

Go is $5 a month for one editor. Plus is $15 with 10 editors, then $5 per extra editor. Both include their monthly price as shared usage credit, unlimited Spaces and custom domains, and 1 TB of cached delivery a month. Usage beyond the credit is billed monthly. No annual plans.

What happens when I hit a limit?

On Free, exceeding an allowance triggers a review and may lead to suspension until the allowance resets, retained storage falls below its limit, or the team upgrades. Above 500 MB, new publishes and uploads stop; existing Spaces keep serving unless suspended. Data and exports remain available. Paid plans charge for usage above the shared credit, with an optional spending cap.

Can I use my own domain?

Free includes 20 custom domains per team; Go and Plus include unlimited domains. Domains registered through Spacefast or WordPress.com, or using Spacefast DNS, do not count toward the Free limit. Wildcards need Plus. Managed HTTPS is included; registration and renewal cost extra.

What account do I sign in with?

A WordPress.com account. Spacefast is an Automattic product and doesn’t invent another login. One account covers your spaces, your team and your domains.
