Framer is an AI-powered design and publishing platform that lets designers create highly interactive, production-ready websites without writing code. Built on React under the hood, Framer generates real component-based code that performs at a framework level — enabling smooth animations, scroll effects, and responsive layouts that look professionally designed. It's the go-to tool for SaaS marketing sites, designer portfolios, and startup landing pages, and is trusted by companies like Pitch, Linear, and Loom. Framer serves all site assets from its proprietary CDN (framerusercontent.com) and injects distinctive data-framer-* HTML attributes throughout the DOM, making it one of the most reliably detectable AI builders. Sites are hosted on Framer's global infrastructure with custom domain support, and pricing starts at $0 for a Framer subdomain with paid plans from $10/month.
