B12
B12 is an AI website builder that generates a complete site from a short prompt and provides SaaS hosting, content editing, commerce, and client-management tools. Founders can launch on a B12 subdomain or their own domain, edit sites via natural-language prompts, and manage client workflows from one platform.
linked official pages list a Free tier ($0/month) on a B12 subdomain, a Website plan at $24/month, and a Website + Client Engagement plan at $78/month, plus a promotional $1 for 7 days trial. Professional and Advanced are described but without per-month prices on the linked official pages.Is B12 right for you?
Good for
- Founders who want to generate and publish a complete website quickly from a short prompt and manage site content and client workflows in one SaaS platform.
- Generates a complete first draft very quickly — B12 documents a roughly two-minute prompt-to-draft flow.
- Allows natural-language site edits via an AI agent — you can update pages by telling the B12 AI Agent what to change.
Keep in mind
- Free plan imposes daily/monthly AI credit limits which could restrict heavy editing or iterative generation.
- Promotional trial is temporary ($1 for 7 days) rather than a permanent free trial of paid features.
- Teams that require on-premise or self-hosted website solutions; B12 is delivered as a hosted SaaS and uses tiered plans—confirm Professional/Advanced plan pricing and any setup fees with B12 before upgrading.
Pricing and plan limits
The pricing pages show specific monthly amounts for Free, Website ($24/month), and Website + Client Engagement ($78/month) and the $1 for 7 days promotion; the documentation does not list numeric monthly prices for Professional or Advanced plans.
