Platform Overviews
Lovable
Lovable (formerly GPT Engineer) is a full-stack AI application builder that creates complete React web applications — including frontend, backend logic, and Supabase database — from natural language prompts. Unlike website builders that produce marketing pages, Lovable builds interactive applications with user authentication, real-time data, and API integrations. It's used by startups and developers to rapidly prototype SaaS products, internal tools, and web apps that would otherwise require a development team. Lovable has surpassed 1 million users and powers thousands of production applications. Sites can be detected through requests to lovable-uploads.s3.amazonaws.com for stored files and *.lovable.app domains for hosted projects. Pricing starts free with a usage cap, and Pro plans begin at $20/month.
Webflow
Webflow is the most powerful no-code website builder available, offering pixel-perfect visual design control with a built-in CMS, e-commerce, and advanced animation capabilities. Unlike most builders, Webflow gives designers and developers full CSS control through a visual interface — making it popular with agencies, freelancers, and in-house design teams who need professional results without a frontend developer. Every Webflow page is uniquely identifiable through injected data-wf-page and data-wf-site attributes on the HTML element, proprietary CSS classes (w-nav, w-layout-grid, w-dyn-item), and assets served from uploads-ssl.webflow.com and assets.website-files.com CDNs. The Webflow JS runtime (webflow.js) is loaded on every published site, and Webflow-hosted sites return server: Webflow in their HTTP headers. Site plans start at $14/month, with workspace plans for agencies from $19/month.
