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.
Bolt.new. Rapid prototypes, throwaway demos and exploring an interface idea before committing. Excellent for showing a concept in a meeting tomorrow.

Plan price
Bolt.new
Every change you ask Bolt to make consumes tokens, and larger projects consume more per request because there is more code for the AI to read. The Free plan allows 300,000 tokens a day and a million a month, which is enough to try it properly. Pro, at $25 a month billed monthly, starts at 10 million tokens a month with no daily cap, and unused tokens roll over to the next month. Yearly billing saves up to 28%.
Subscription
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.
Bolt.new
Anything intended to be maintained. Output quality varies enough between runs that building a real product on it means accepting an unpredictable foundation.
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.
Bolt.new
Choose Bolt for prototypes, demos and experiments where getting something working today matters more than how the code looks tomorrow. The free plan is enough to judge it; Pro is worth it once you are using it every week.
