Looking for a Framer alternative?

What is B12?

B12 is an AI website builder that creates websites, online stores, and web apps from a short description. You type what you do, and B12 hands back a working first draft in about two minutes.

From there, an AI Agent keeps building with you: add a login, a booking page, or an invoice whenever the business needs it. Every site comes with built-in tools for SEO, online payments, scheduling, and client management, and over 4 million websites have been built on B12.

How is B12 different from Framer?

Framer is built for designers. Its canvas feels like Figma, and it turns out some of the most polished, animation-rich Figma sites and marketing pages in no-code. But Framer's CMS collections handle content only, blog posts and collection data; it limits CMS to 1,000 items on the entry plan with no code export. There's no built-in login, no server-side logic, and no native payments, contracts, or scheduling without custom code.

B12 starts from the opposite end. You describe your business, and the AI Agent builds a working site designed to support real functionality behind it, like a login page, a database, a payment flow. Ask for it, and B12 wires it in and integrates with Stripe, Calendly, and other tools while keeping your keys safe behind the scenes.

Is B12 good for non-technical users?

Yes. B12 is beginner-friendly and built for people who don't code and don't want to learn Framer's design tools either, small teams and solo owners included. You describe your business or idea in plain language, and the AI handles layout, copy, and structure for the first draft. 

Framer's learning curve is gentler than a full code editor. But it's still a design tool that most agencies and design-savvy users spend real time on before the canvas, breakpoints, and interaction settings feel natural.

What can you build with B12?

With B12, you can build websites for a marketing page, a booking flow, an online store, or a client portal with logins and a dashboard for managing multiple clients, plus contracts, invoicing, and email marketing in one place. 

Framer is strongest for marketing and portfolio sites where visual design, motion, and custom components carry the page. If the goal is a site that also runs the business, collecting payments, booking appointments, managing contracts, B12 builds that in as part of the platform instead of requiring a stack of third-party tools bolted onto a Framer website.

Can B12 build a real backend?

Yes. Tell the AI Agent what you need, like a login page with email signup and a confirmation message on submit, and it builds that in for you. You get user accounts, a database, payments, and bookings, plus integrations with Stripe and Calendly, with your keys kept secure. There’s also no vendor lock-in on the tools you already use.

Framer has no equivalent. Adding logins, a database, or payments means custom code, third-party plugins, or wiring in an external service yourself.

When should you pick B12 over Framer?

Pick B12 if you want a site that also runs the business, with payments, bookings, and contracts built in, and you'd rather describe what you want than design it by hand. Use Framer if design flexibility and animation quality matter most and you're comfortable being the designer. It’s also a good option if you're building a portfolio or marketing site and a real backend isn't part of the plan. 

The right website builder depends on your goal and budget. Some people run both: one for the polished landing page, one for the customer-facing app.
