Most “AI builders” want you to switch to their model, then figure out hosting later. On November 9, Automattic announced Spacefast, a new company pointed at the opposite habit: keep the AI you already use, including coding agents, and give that agent a place to put the work online.
The pitch, in the company’s words, is that AI makes a first draft of a website or app fast, but finishing and shipping still means new tools, setups and sign-ins — and that many AI builders then ask you to pay for their AI a second time. Spacefast says it works with the AI you already have.
What they say is available now
Per the announcement:
- Bring your own AI. It names ChatGPT and Claude apps, personal assistants such as Muse, Grok Bot, OpenClaw and Hermes, and coding agents such as Claude Code, Codex and Cursor. It also says you can connect agents through an API, CLI and MCP, and that Spacefast is available as a plugin on Claude, ChatGPT, Grok Bot and more.
- A ready place to land the work. Deploy and host, a domain and a database come with Spacefast. It lists out-of-the-box support for stacks including Vite, TanStack Start, Next.js and Astro.
- Private until you share. Ask the agent to put the work online and you get a private link. You choose who sees each Space. Team or client comments can sit on the page; the release says your agent can turn those comments into fixes.
- Permissions on the agent. You choose what the agent can access and do, with approval checks for sensitive actions.
- You keep the files. Download files from any version in your history and export the app’s data at any time, according to the post.
What is still coming — don’t treat it as shipped
The same release is clear that some pieces are not available yet. Built-in app authentication, transactional email and shared team knowledge (playbooks, past decisions, brand context, shared skill files) are described as launching in the coming weeks. I’m not counting those as part of today’s product.
Claims to keep in the vendor column
Automattic says Spacefast runs on WordPress.com’s infrastructure, which the post says handles more than 15 billion page views a month, and that WordPress VIP and Pressable customers can connect it to a site they already run. Pricing in the release: free to start, with Personal, Go ($5/month) and Pro ($15/month per member) plans described. Those are the company’s numbers and plan claims, not my measurements.
Also treat “live in seconds,” “far better result from the same prompt,” and similar launch language as marketing, not as a test result. The post doesn’t publish latency numbers, quality scores or a controlled comparison against other hosts.
What I’d check before pointing an agent at it
- Permissions first. Confirm what the agent can deploy, who can open the private link, and what still needs your approval.
- Export path. Download a Space and open it outside Spacefast before you depend on it.
- Stack fit. Try the stack you actually ship (not only the starter templates) and see what the agent can fix from on-page comments.
- Don’t wait on the roadmap. If you need auth, email or shared team knowledge today, the release says those are still coming.
For teams here in Mexico already paying for a coding agent in dollars, a host that doesn’t force a second AI subscription is the interesting part of this launch — if the permissions and export story hold up on a real project.
