Who each one is for
B12. Anyone who wants to go from a description to a finished, working site without assembling it: small businesses, founders, freelancers and teams who need a website, a store or a simple web app live this week, and would rather talk to an AI than learn a design tool.
Replit. Technical founders and developers who want AI acceleration without giving up the ability to edit. Deploying where you built removes a whole category of setup friction.

Who should skip each one
B12
A designer who wants pixel-level control over every layout, where Webflow or Framer fit better, or a merchant with a large, complex catalog, where Shopify's commerce depth wins. If you need to own and hand-edit an app's codebase, a code-first AI app builder such as Lovable or Replit is the better home.
Replit
Non-technical users building a marketing site. The editor assumes familiarity with files and processes, and there are simpler routes to a website.
The bottom line
B12
B12 is the AI builder we would point most people to first: one prompt gives you a complete site, store or simple web app, and you keep improving it by talking to the same AI. Start on the free plan to see the draft, and move to the $24 Website plan when you want your own domain, commerce and backends.
Replit
Choose Replit when the app is meant to last and you, or someone you will hire, will keep working on the code. Core is enough to find out; Pro is for teams building seriously with the agent every day.
