Platform Overviews
Sanity
Sanity is a modern headless CMS with a real-time 'content lake' — a cloud database optimized for structured content with a powerful query language (GROQ) and flexible schema definition. Unlike other headless CMS platforms, Sanity stores all content in a single collaborative workspace where editors can see changes in real-time, similar to Figma for content. It's popular with digital agencies and product teams who need a flexible, developer-configurable CMS that doesn't force a rigid content model. Sanity-powered sites serve all media through cdn.sanity.io, and this CDN domain in image URLs is the primary detection signal. The Sanity Studio (the editing interface) is typically deployed as a separate /studio route on the same domain, and some sites leave the __sanity object in their JavaScript globals. Sanity pricing is usage-based with a generous free tier and Growth plans from $15/month.
Framer
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.
