Pros and cons

B12

Best for: Accountants, lawyers, consultants and other service firms

Price: Free on a b12sites.com address; Website $24 a month, Website + Client Engagement $78 a month

Pros: AI drafts tuned to professional services; Client tools such as scheduling and payments on the higher plan; Cheap $1 trial

Cons: Big jump from $24 to $78; Top plans need a sales conversation and setup fee; Annual prices not shown

We.Inc

Best for: People who want to describe a site or web app in plain English and have AI build it

Price: Free plan: up to 3 template sites on a we.inc address, no AI. AI building from $20/mo (Starter, 250 credits). Pro $49/mo, Max $99/mo.

Pros: Describe what you want in chat and AI builds a full, editable site or app; Edit by clicking on the page, by asking in chat, or in a real code editor; Export the React and TypeScript code to GitHub, so you are never locked in; Unlimited sites on paid plans, custom domains from Starter

Cons: The free plan is templates only; AI building needs a paid plan; Newer platform with a smaller app marketplace than the big names; Store features are simpler than a dedicated ecommerce platform

Which B12 plan fits?

The Website plan covers a single practice that wants an AI-drafted site on its own domain. The Client Engagement plan makes sense if you will use B12's scheduling, intake and payment tools in place of separate apps; if you already pay for those, stay on Website.

B12 or a general AI builder?

B12's strength is its focus on service firms. A general AI builder is more flexible for other kinds of business and for web apps.

Where We.Inc fits: the free plan publishes up to 3 template sites on a we.inc address, with no AI and no custom domain, and needs no credit card. AI building, where you describe the site and it is written for you, starts at $20 a month (Starter, 250 credits); Pro is $49 and Max is $99.
