Spacefast: Automattic's hosting for AI-built apps

The hard part of an AI-built app was never the code. It was where the code lives after the chat ends. Spacefast, which Automattic launched on November 9, is hosting built for that gap. You ask Claude, ChatGPT or Cursor to publish, and a live link comes back in the chat. It runs on the same infrastructure as WordPress.com. For a small business that builds quick internal tools with an AI assistant, this is now one of the shortest paths from prompt to URL. It is also a quick way to put something live that nobody owns.

What actually happened

Per Automattic's launch post and Spacefast's own site:

• Who runs it: a new company inside Automattic, led by founder and CEO Batuhan İçöz. It soft-launched in September and opened to everyone on November 9.
• Where it works: ChatGPT and Claude apps, Claude Code, Codex, Cursor, and other assistants, plus "any MCP client." There is an API, a CLI (npx spacefast publish), and an MCP server. Git push to main also deploys, and other branches get preview links.
• Backend: a SQL database per Space (MariaDB, per the founder's post), file uploads, built-in analytics, and custom domains. Automattic says app authentication is "coming soon." Transactional email is also listed as coming soon.
• Versions: every publish is a new version with its own permanent URL, and you can roll back.
• Pricing: Personal is $0 with $1 of usage a month and 20 Spaces. Go is $5 a month and Pro is $15 a month. Automattic says it charges "for infrastructure, not AI credits."
• No account needed: anyone can publish. Spacefast's FAQ says unclaimed Spaces "normally expire 33 hours and 20 minutes" after the last change, capped at 30 days.

Why AI app hosting matters for your business

Claim it or lose it. An agent can publish without an account. That is great for a demo. It is a problem when the quote calculator your manager built over lunch disappears on Thursday. Claim every Space you intend to keep, and put it under a company login, not a personal one.

Auth is not there yet. Until built-in login ships, do not put customer records, pricing sheets or anything private in a Space and trust an unlisted link to hide it. Spaces are private by default, and share links can take a password. Use both.

Own the domain, not the host. Spacefast supports custom domains on the free plan. Point a subdomain you control at it. If you outgrow it, you move the app and keep the address your team and customers already use.
