Mozilla Solo is shutting down on November 30, 2026. The honest alternative for solopreneurs: where to move your site and how Kompozy covers the content.
If you are searching "Mozilla Solo alternative," it is almost certainly because Solo is closing. Mozilla has said all Solo sites and data will be deleted on November 30, 2026, so this is not a casual comparison — it is a migration with a deadline.
I am going to be unusually blunt about one thing up front, because it saves you time: Kompozy, which I run, is not a website builder and will not replace Solo one-for-one. If what you need is a hosted site living at your domain, the right move is a living website builder or a static host — not Kompozy. I will point you to those honestly below rather than pretend my product is something it is not.
What a Solo refugee actually faces is two separate jobs that Solo quietly combined. Job one: have a website. Job two: get people to it. Solo did job one and left job two entirely to you. Most solopreneurs who loved Solo loved it for removing work they did not want to do — and the ongoing work of making content and showing up across platforms is a bigger version of exactly that. That second job is where Kompozy fits, and it is a better match to Solo's original appeal than any static export is.
So read this as a two-part answer: move the site to a real builder, and put a content engine around it. Everything below is grounded in Solo's own shutdown documentation and Kompozy's current capabilities as of 2026-10-02.
Mozilla Solo is an AI website builder for solopreneurs. You answer a few prompts about your business and Solo generates a simple professional site — layout, copy, images, hosting, and a custom domain bundled together — so a non-technical person can be online quickly without a template editor or a hosting dashboard. It launched out of Mozilla's innovation group (beta in late 2023, 1.0 in 2024) and offered a free tier plus paid Solo Pro and Grow plans. That is the whole product: generate and host a straightforward website. It was never a content or marketing tool — it did not clip video, write ongoing social posts, draft newsletters, or publish anywhere but the site itself. And as of 2026 it is being discontinued: sites and data delete on November 30, 2026, with an HTML-plus-CSV export, prorated refunds for Pro and Grow, and a domain-transfer path (Name.com, or a separate route for IONOS domains) as the off-ramp.
The reason to move is not a flaw — it is that Solo is shutting down, and staying put means losing your site. That forces a choice, and it is worth using the moment to fix the thing Solo never addressed. Solo got you a site and stopped. It had no ongoing content generation, no short-form video, no carousels or quote cards, no blog or newsletter production, and no multi-platform publishing. A site that sits at your domain does not, by itself, bring anyone to it — that takes a steady stream of content on social, in search, and in inboxes, which is precisely the work a one-time site generator left on your plate. If you felt your Solo site was "done" but quiet, that gap is why. Replacing Solo well means solving both halves: re-host the site somewhere maintained, and add the content engine Solo never had.
| Feature | Mozilla Solo | Kompozy | Note |
|---|---|---|---|
| Hosted website at a custom domain | Yes | No | Solo built and hosted a site; Kompozy is not a website builder. Use a living builder or static host for the site itself. |
| Bundled hosting + domain | Yes | No | A Solo convenience. Kompozy publishes to your own social/blog/email accounts, not a hosted site. |
| AI generates the core asset from prompts | A website | Content | Different outputs: Solo generates a site; Kompozy generates posts, video, images, blogs, and newsletters. |
| Ongoing content generation (video/image/text) | No | Yes | Solo was a one-time generator; Kompozy produces new content continuously. |
| Short-form / clipped video | No | Yes | Persona and avatar shorts, clips from long-form — none of which Solo did. |
| Carousels, quote cards, infographics | No | Yes | Brand-exact image formats Solo never produced. |
| Blog articles & email newsletters | Partial | Yes | Solo could hold static pages; Kompozy drafts full blog articles and newsletter bodies. |
| Multi-platform social publishing | No | Yes | Kompozy fans output across the eight social platforms plus blog and email. |
| Scheduling & autopilot | No | Yes | Kompozy schedules and publishes on a per-post review pipeline; Solo had no queue. |
| Brand-voice governance (Persona Brief) | No | Yes | Kompozy enforces tone and banned phrases across every output. |
| Still operating in 2026 | No | Yes | Solo is deleted November 30, 2026. This is the whole reason you are here. |
| Data export / portability | Partial | Yes | Solo gives a static HTML + CSV export; Kompozy outputs land in your own accounts and can be downloaded. |
| Tier | Mozilla Solo plan | Mozilla Solo price | Kompozy plan | Kompozy price |
|---|---|---|---|---|
| Entry | Solo Free | Free (discontinued Nov 30, 2026) | Kompozy Starter | $199/mo (5,500 credits) |
| Mid | Solo Pro | ~$20/mo (being refunded & wound down) | Kompozy Pro | $499/mo (18,000 credits) |
| Top | Solo Grow | ~$85/mo (being refunded & wound down) | Kompozy Enterprise | Custom (sales-led) |
Here is the honest pitch, and it starts with what Kompozy is not: it will not rebuild or host your Solo website. Take the site to a living builder or a static host — that half is simple and I would rather you get it right than oversell you.
The half worth your attention is the one Solo never touched. A site at your domain is a storefront; content is the foot traffic. Solo generated the storefront once and left you to drive the traffic by hand, which is why so many Solo sites ended up polished and silent. Kompozy is the engine for that second job: feed it one source — a short video, a few notes, an offer — and it generates finished, on-brand shorts, carousels, quote cards, blog articles, and newsletters, then schedules and publishes them across nine platforms on autopilot through a per-post review pipeline.
If Solo appealed to you because an AI did the work you did not want to do, that appeal maps onto content far more than onto a one-time page. Re-host your site, then start on Kompozy Starter at $199/mo (5,500 credits) and let the engine keep producing while you run the business. Bring your own API keys to run leaner. The site keeps the lights on; Kompozy is what brings people through the door.
It depends which half you mean. For the website itself, move to a living AI builder like Framer, Durable, Wix, or Hostinger, or Carrd for a simple one-pager — or re-host your HTML export on a static host like Netlify or Cloudflare Pages. For the ongoing content and distribution Solo never did, a generation-and-publishing engine like Kompozy is the fit.
Not as a website builder — Kompozy does not build or host sites, so it cannot replace Solo one-for-one. It replaces the part Solo was missing: generating and publishing content across social, blog, and email. Use a real site builder for the site and Kompozy for what drives people to it.
All Solo sites and data are deleted on November 30, 2026. Before then: export your site from Account Settings (Download Website Data gives an HTML ZIP plus a CSV of image links — download the images individually), transfer any Solo-registered domain (Name.com, or a separate path for IONOS domains), and confirm any Pro or Grow refund.
Only if you do not transfer it. Domains registered through Solo must be moved before the service closes — Mozilla points users to Name.com, with a separate route for domains bought through IONOS. Start early so the address your audience knows stays yours.
They are different categories, so it is not a like-for-like. Solo had a free tier and paid plans (roughly $20/mo Pro and $85/mo Grow) that are now being refunded and wound down. Kompozy is a paid content engine starting at Kompozy Starter $199/mo (5,500 credits), with Pro at $499/mo (18,000 credits); you can bring your own API keys to run leaner. You would still pay a separate (often low or free) cost for whatever hosts your actual website.
