On November 9, 2026, Automattic opened Spacefast to everyone, a service for publishing AI-built websites and apps. It had soft-launched in September. The announcement still lists built-in app-user authentication as a forthcoming feature.
Who should pay attention
Small teams that have already made a service-page demo, presentation or simple tool with AI and want to share it. Nadali’s editorial takeaway: before sending it to a client, check how long it will remain available and who can open it, alongside its appearance.
Two different links
According to the Spacefast FAQ, you can start without an account. An unclaimed Space normally expires 33 hours and 20 minutes after creation or the latest publish that changes files, capped at 30 days from creation. Claiming removes that deadline.
New Spaces are private: the ordinary URL alone does not grant access. A separate viewer link works for anyone holding it; you can also invite specific people. Search indexing is a separate setting.
The account-claim link serves a different purpose. The claim page explicitly says to keep it private and not paste it into a chat or support request.
What the free plan means
The pricing page allows commercial use on the $0 Personal plan, with $1 of usage included each month. After that allowance is exhausted, deployed Spaces keep serving, but new builds and Workers, server-side compute processes, pause. A page remaining accessible therefore does not establish that all its functions still work.
Before handing it over
Our editorial recommendation for a first trial project:
- Claim the Space under an account controlled by the business if the page needs to last longer.
- Send the reviewer the viewer link and check access from their side.
- Test buttons and forms with non-sensitive sample data.
- Assign someone to monitor limits, maintain the page and own a fallback way for clients to make contact.
Nadali has not created a test account, tested the service or verified claimed savings. This is a review of published terms as of November 10, not a recommendation to migrate a production website.
