Mozilla Solo, the AI website builder Mozilla launched in December 2023 under its Innovation Projects banner, is closing. The Solo homepage now says the product will cease operations on November 30, 2026, and registrations are already closed. The Register reported the shutdown on November 13.
If you still have a site on Solo, the deadline is the part that matters. Mozilla's Solo Shutdown FAQ doesn't soften it: every Solo site and its data gets wiped on November 30, 2026, with no way to recover your site, account, or data after that date.
$ whoami → hosting nerds since 2012 You have a little over two weeks. Download first. Then decide where the site lives next.
The timeline
- December 12, 2023: Mozilla introduced Solo on its blog as an AI website builder for solopreneurs.
- October 1, 2026: Mozilla says it first notified customers and started a 60-day transition. That date is also the one it uses to calculate prorated refunds for Solo Pro and Grow subscriptions.
- Now: Registrations are closed. Paid subscriptions will not renew.
- November 30, 2026: Solo shuts down. Sites, accounts, and data are deleted.
According to The Register, roughly 54,000 people made sites with Solo's AI tools and left the hosting to Mozilla, many of them on their own custom domains. Mozilla told The Register that experimentation is part of its mission, and that ending a product is sometimes the decision it makes. The hosting still ends on a fixed date. Treat anything that exists only on Solo as temporary.
Export the site, and actually save the images
Mozilla's export is in Account Settings, not a support ticket.
- Log in to Solo.
- Open the menu at the top right and choose Account Settings.
- In the Account Settings popup, click Download Website Data.
You get a ZIP file with an HTML export of the website, a CSV file of links to your image assets, and your contact form and newsletter submissions.
The images themselves are not in the ZIP. Mozilla says you have to download each image from the links in that CSV before November 30. Do that first, while the links still work. Keep the ZIP, the CSV, and the image files together in one folder you control — a laptop, an external drive, or storage you already use. Do not leave the only copy in a downloads folder you might tidy later.
An HTML export is a copy of the pages, not a one-click move into another builder. Mozilla does not say how much work it takes to turn that export into a working site somewhere else, and The Register noted the same gap. Open the HTML on your computer, confirm the text is there, and plan to put the images you downloaded back in place. Contact forms and newsletters will not keep running on Solo's servers after November 30. The export gives you the submissions you already collected, not a replacement form service.
Keep the domain, or move it
The domain and the site are separate. Saving the HTML does not, by itself, keep your domain name pointing at anything.
If you bought the domain through Solo Domains (not IONOS), Mozilla's FAQ says you need to migrate it to Name.com, its domain partner:
- Create a Name.com account, or log in if you already have one.
- Complete the default account contacts on Name.com's Account Contacts page — Registrant, Administrative, and Technical. Name.com will not accept the transfer until those are filled in.
- Copy your unique Account Code from the top-right corner of the Name.com dashboard.
- Email that Account Code to support@soloist.ai. Mozilla says it will transfer the Solo Domains account to Name.com and email you when it is done.
- Add billing information at Name.com. If you don't, Name.com will remind you as the domain's renewal date approaches.
Start this before November 30. A transfer that is still sitting in an inbox on shutdown day is a problem you do not want.
If you bought the domain through IONOS, the FAQ carves that path out of the Name.com move and does not give a second set of steps. Check the domain in your IONOS account, and write to support@soloist.ai if it is unclear who currently holds it.
If the domain was already yours and you only pointed it at Solo, it should still be at your registrar. After November 30 it will resolve to a site that no longer exists, so you will need to update its DNS records to whatever host you use next. Mozilla's FAQ does not walk through that case. The registrar account is the place to start.
Where the site can go next
Mozilla's FAQ lists Wix, Squarespace, and WordPress as popular website hosts, and also points at AI website builders such as Bolt or Lovable. Those are suggestions, not a migration program. None of them will automatically import a Solo account. You will be rebuilding, or at least re-uploading, from the files you saved.
A practical way to choose:
- A site builder (Wix, Squarespace, WordPress.com, or another builder you already like) if you want a visual editor, forms, and hosting in one place, and you are willing to reconstruct the pages.
- WordPress on a regular web host if you want to own the files and be able to move again later without waiting on another company's product roadmap.
- A straightforward web host for the HTML export if the saved pages are good enough and you mainly need them online again under your domain. Any host that will serve static files can do this. Independent hosts such as Thexyz or Driond sit in that category, alongside the usual shared-hosting and static-host options. Confirm what the host actually offers before you sign up; this is not a ranked list, and we are not quoting prices.
- Another AI builder (Mozilla mentions Bolt and Lovable) if you would rather regenerate the site than tidy the exported HTML. You will still need your own copy of the text, images, and leads.
If the same domain also handles email — you@yourbusiness.com — that mail does not move with a website export. Set the mail up at a mail host, or at a web host that includes it, and keep the MX records in mind when you change DNS. Thexyz, for example, sells email on a domain you already own. The website and the inbox can live in different places.
Whatever you pick, get the new site up and the domain pointed at it before November 30 if you can. After that date, Solo will not be there as a fallback.
Refunds, and where to ask for help
If you have an active Solo Pro or Grow subscription, Mozilla says it will issue a prorated refund for the unused portion of your current billing period, calculated as of October 1, 2026. The refund goes back to the original payment method. You do not have to file a request, and the subscription will not renew.
Further questions go to support@soloist.ai, which is also the address for the Name.com Account Code.
A short checklist
- Log in and download the website data ZIP from Account Settings.
- Open the CSV and save every image before November 30.
- Keep the ZIP, the CSV, the images, and the form and newsletter submissions in a folder you control.
- Open the HTML locally and confirm the copy is there.
- If the domain is a Solo Domains registration (not IONOS), create or log in to a Name.com account, fill in the contacts, and email the Account Code to support@soloist.ai.
- If the domain is at IONOS or at another registrar, confirm you can still log in and update DNS.
- Choose a new host or builder, put the site there, and point the domain at it before November 30 if possible.
- If you use email on that domain, point or confirm the MX records so mail does not break when the website moves.
- After the new site is live, check the pages, images, and contact form.
Hosting know-how, minus the hype: save the files and the domain first. The new homepage can wait a day. The export cannot wait until December.
