Mozilla's Solo AI website builder shuts down; all sites and data deleted November 30

Mozilla is retiring Solo, its AI website builder, and every site built with it now has a firm expiry date. A shutdown FAQ published on Solo's support pages, which surfaced on Hacker News on October 2, states that all Solo websites and data will be deleted on November 30, 2026 — and that nothing can be restored afterward.

Exporting your site

The FAQ gives a short export path: log in to Solo, open the top-right menu, select Account Settings, and click Download Website Data. The ZIP you receive contains an HTML export of the site, a CSV file with links to image assets, and records of contact form and newsletter submissions.

One gap stands out. Original image files are not included in the archive, so each one has to be fetched individually through the links in the CSV before the November deadline.

Refunds happen automatically

Paid subscribers do not need to chase a refund. According to the FAQ, anyone with an active Solo Pro or Grow subscription will get a refund covering the unused part of their current billing period, calculated on a prorated basis as of October 1, 2026. The money returns to the original payment method with no action required, and subscriptions will not renew.

Domains must move to Name.com

The domain situation adds work for some users. Domains purchased through Solo Domains — as opposed to IONOS — have to be transferred to Name.com, the registrar Solo is handing those accounts to. The steps the FAQ lays out:

1. Create a Name.com account, or log into an existing one.
2. Verify the email address on that account, since Name.com requires a verified account before it can accept a transfer.
3. Locate the unique Account Code shown in the top-right corner of the Name.com dashboard.
4. Email the code to [email protected]; Solo will then move the account over and send confirmation by email.
5. Add billing information to Name.com, which will send reminders as renewal dates approach if this step is skipped.

Domains bought through IONOS rather than Solo Domains are excluded from this transfer process.

Where to rebuild

For replacements, the FAQ names Wix, Squarespace and WordPress as popular hosting options, and also points to AI site builders such as Bolt and Lovable. Users with further questions are directed to [email protected].

Why it matters

Solo's closure is a compact case study in the risks of AI-generated convenience. A builder that promises a working site in minutes can be switched off just as quickly, and the exit terms decide how much work users inherit. Here the financial wind-down is comparatively painless — automatic prorated refunds and no renewals — but the data exit is narrow: a flat HTML export plus a spreadsheet of image URLs is not a one-click rebuild anywhere, and every image has to be pulled by hand. The deletion is absolute and the deadline is under two months away, so anyone with a live Solo site, a custom domain, or stored form and newsletter submissions needs to export, re-host, and transfer their domain sooner rather than later. It is also a useful checklist moment for anyone choosing a hosted builder, AI or otherwise: check what an export actually contains before committing content to the platform.
