How to pick the right one

A few honest questions to point you the right way.

  • Do you want to write code? If yes, a developer tool fits. If no, B12 skips it.
  • Do you need it live today? B12 gives you a working draft in about two minutes.
  • Is this a business, not just an app? B12 has booking, payments, and email built in.
  • Do you want real backend features? Ask the AI Agent and it builds logins, databases, and checkout in.
  • Do you want to keep control? Edit in chat, click to edit visually, or open the code.
  • On a budget? B12 is free to start. Upgrade when you grow.

Build it by asking

Tell B12 what you have in mind and get a real, working site or web app back in minutes. Want it to do more? Ask the AI Agent:

  • Add a login so members can see their dashboard.
  • Turn this CSV into a pricing table.
  • Set up a booking page that syncs with my calendar.
