The top three, in brief
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.
Lovable
Founders and product people validating an idea, internal tools, and prototypes that need to be real enough to test with users. The Supabase wiring being handled for you removes the step that usually stalls non-developers.
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.
