Mozilla's Solo website builder shuts down and deletes all sites

Mozilla's Solo website builder shuts down and deletes all sites

13 November 2026: Solo, the AI website builder Mozilla launched for sole traders, will cease operations on 30 November 2026, and every Solo website, account and its data will be deleted that day with no way to recover them. Registrations are already closed, and anyone with a site has to export it before the deadline.

Not yet independently verified. Mozilla's own statement is quoted only through The Register, and we found no Mozilla newsroom post. The number of sites affected is not stated; the 54,000 figure is The Register's count of people who used the builder. We will update this when it can be confirmed, and remove this note.

What is deleted, and when it was announced

Solo's own FAQ says the shutdown was announced on 1 October 2026 and that "All Solo websites and data will be deleted on November 30, 2026." The home page repeats that Solo "will cease operations on Nov 30, 2026" and tells customers to download their websites first. Mozilla told The Register the notice gave a 60-day transition period, which leaves a little over two weeks from today.

Solo began in December 2023 as a Mozilla Innovation Project meant to help sole traders put up a page for their services. The Register puts the number of people who used the builder at about 54,000, many of them relying on Mozilla to host their sites, including on custom domain names.

Taking the site out in a ZIP

The export is done from inside the product: open the menu in the top-right corner, choose Account Settings, then click Download Website Data. The ZIP holds an HTML export of the site, a CSV file with links to its image assets, and the submissions from contact forms and newsletter sign-ups.

The image files themselves are not in the ZIP. Each one has to be downloaded separately from the links in the CSV before 30 November, and the links point at hosting that goes away on the same date. The Register points out that the FAQ does not say how much work it takes to turn the export into a complete working site elsewhere. An HTML export carries the pages, but form handling and newsletter lists will need a new home.

Refunds and domains

Customers with an active Pro or Grow subscription receive a prorated refund for the unused part of the current billing period, calculated as of 1 October 2026. It goes back to the original payment method without a request, and the subscription will not renew.

Domains bought through Solo Domains, which the FAQ distinguishes from those bought through IONOS, must move to Name.com, Solo's domain partner. The steps are to create or open a Name.com account, complete the Registrant, Administrative and Technical contacts, find the Account Code in the top-right corner of the Name.com dashboard, and email it to support@soloist.ai. Solo then transfers the domains and sends a confirmation. Billing information should be added at Name.com, or renewal reminders will follow. The FAQ does not say how IONOS domains are handled.

Where Solo points its users

The FAQ names two groups of alternatives: the site hosts Wix, Squarespace and WordPress, and the AI website builders Bolt and Lovable. Questions go to support@soloist.ai or to the Solo Reddit group. Mozilla's statement to The Register said "Sometimes, that means making the decision to bring a product to an end." The Register also suggests Mozilla could have found a commercial partner to take on the users; the FAQ names none.
