Quick answer
Framer generates pages inside its own design tool and hosts the result, with CMS and forms included; best for founders who want a marketing site live today. Relume generates a sitemap and wireframes from a description and exports to Figma or Webflow; best for agencies building many sites on their own stack. Lovable generates a real front-end codebase from a prompt; best for web apps rather than brochure sites. Free tiers exist for all three.
"AI website builder" now describes three quite different products. The right one depends on whether the output you want is a website, a design, or an application.
Framer: prompt to live site
Describe the site and Framer produces pages you can edit on a canvas, with real design controls, responsive breakpoints, and a CMS. Publishing is one click to Framer hosting, from $5 a month on the smallest plan. AI also rewrites copy and translates whole sites. The catch is that you are on Framer for good; there is no export to another host. For a startup landing page or portfolio, that rarely matters.
Relume: structure for professionals
Relume does not host anything. It takes a one-line brief, proposes a sitemap, generates wireframes for every page from its library of over a thousand components, drafts the copy, and exports the lot to Figma or Webflow with a style guide attached. An agency that ships a site a week saves the blank-page phase every time. It costs from $32 a month per seat after a one-project free tier, and it assumes a Webflow or Figma workflow.
Lovable: apps, not brochures
Lovable builds working web applications, with authentication, a database via Supabase, and a real code repository you can open in an editor. It can make a marketing site, but that undersells it and overcomplicates a simple job. Use it when the thing you are describing has users who log in and data that changes.
What none of them fix
- Generic copy: every generated site sounds like every other until a person rewrites it
- Stock-looking imagery: budget for real photos or a proper image generator
- SEO basics: check titles, descriptions, and page speed yourself; defaults vary
- Brand: a builder gives you a respectable site, not a distinctive one
Bottom line
Framer for a marketing site you want live this afternoon. Relume if you build sites for clients in Webflow or Figma. Lovable if it is really an app. Pick by the output you need, not by which demo looked best.
