Database
Supabase is a database with an AI Score of 10/100 (Unknown). Our detection engine uses 5 signal patterns to identify Supabase-built sites.
Vercel is a cloud platform for frontend developers and teams, purpose-built for deploying static sites, serverless functions, and modern JavaScript frameworks like Next.js, which Vercel itself maintains. The platform is widely adopted by developers building performance-focused web applications, particularly those using React-based stacks that benefit from Vercel's edge network and instant rollback capabilities. Detection of Vercel-hosted sites relies on two distinct HTTP response headers that Vercel injects at the infrastructure level, making identification reliable regardless of how the frontend is built or customized. These headers are consistently present across Vercel's deployment infrastructure, providing a low-noise, high-confidence signal that persists even when sites use custom domains or heavily modified frontends. Vercel operates on a freemium model, offering a generous free tier for personal projects and hobby deployments, with Pro and Enterprise plans available for teams requiring advanced features such as password protection, higher usage limits, and SLA guarantees — a pricing structure that has contributed to its broad adoption across both small developer projects and large-scale production applications.
Supabase is an open-source Firebase alternative built on Postgres, bundling a database, authentication, storage, and real-time subscriptions into one developer platform — widely adopted because it gives teams a full Postgres database (rather than Firebase's NoSQL model) with a similarly fast setup experience. Our engine detects Supabase through 2 script patterns, 2 HTML patterns, and 1 CDN domain tied to its client SDK's API-request conventions and asset delivery. Supabase can be self-hosted or used via its managed cloud; detection doesn't distinguish between the two. Documented at supabase.com.
