B12 vs Plasmic: Features, Pricing and User Reviews 2026

B12 is an AI powered website builder that turns a short text prompt into a complete website in a few minutes. You describe your business or idea, and the AI creates the pages, layout, copy, images, and structure for you.

Once the first draft is ready, you can keep improving it by chatting with the AI Agent, clicking and editing parts of the page directly, or working with the code if you want more control.

B12 also comes with built in business tools such as online payments, invoicing, email marketing, contact management, and appointment scheduling, so you can run your business from the same place your website lives.

If you would rather not build it yourself, B12 also offers expert designed plans where real people help set up and manage your site.

Plasmic is an open source visual builder that helps teams design and build websites, apps, and content without needing to write code. It works like a modern design tool, but instead of just creating mockups, it produces real working pages that connect directly to your codebase.

The platform is built mainly for React and works closely with Next.js. Developers can bring their own components into Plasmic, so marketing and design teams can build pages using the same building blocks used in production, all inside safe design guardrails.

Alongside the visual editor, Plasmic includes a built in headless CMS, data integrations, and support for A/B testing and localization on higher plans. Teams can host anywhere, connect their own data sources, and pair Plasmic with AI coding tools for faster development.
