B12 alternatives

The best B12 alternatives in 2026

The closest B12 alternatives are FNJ, Durable, Wix, Squarespace, GoDaddy and Mixo. B12's help center says its sites can't be exported or hosted elsewhere, so leaving means rebuilding; that's the main reason people compare alternatives. Below, each one compared on what it builds, whether you can take the code with you, where the site has to live and what's free.

FNJ makes one of the builders compared here, so weigh our view with that in mind. Facts about other products come from each vendor's own website, checked in October 2026; plans change, so confirm on the vendor's site before you buy.

Switching isn't always worth it. B12 is a good fit when what it does well is what you need: a service business that wants its site, client intake, contracts and payments in one place.

  • Free plan that publishes on a B12 subdomain
  • Commerce and backends on the Website plan
  • Client tools (intake, contracts, email marketing) on the higher plan

Questions

Does B12 have an AI website builder?
Yes. An AI agent turns a plain-language description into a draft site in about two minutes; you chat with it to change design or copy, add a backend, and set up scheduled tasks.
Can I export my B12 site's code?
No. B12's help center says there is no file or code export another host could use and no local backup download. You can copy text, keep files you uploaded, export contacts and keep your domain.
Do I have to host my site with B12?
Must host with them. B12 compiles and serves sites on its own AWS-based hosting and says sites won't work if downloaded or hosted outside B12.
What's the best B12 alternative if I want to own the code?
Pick a builder with a full code export. FNJ designs marketing sites and exports Next.js or static HTML you host anywhere; GoDaddy also export full projects. Check what stays behind on export, such as forms, stores and databases.
Is there a free alternative to B12?
Wix, Jimdo, Strikingly and Mixo let you publish a site on a free plan, on their own subdomain and with their branding or usage limits; our comparison of free AI website builders lists what each free plan includes. FNJ has no free plan: the Site Pack is $29 once, and you can host the export on a free static plan.
