Platform Overviews

Vercel

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

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.

Key Differences

  • Vercel is a Hosting while Supabase is a Database — they serve different primary use cases and aren't always direct alternatives.
  • Vercel scores higher on AI involvement (10/100 vs 10/100 for Supabase), meaning it relies more heavily on AI for site generation and content creation.
  • Our detection engine identifies Vercel using 2 fingerprint patterns and Supabase using 5 patterns — more signals generally means more reliable detection.

Which Should You Choose?

Choose Vercel if…

  • You prefer a hosting solution
  • You want more manual control over the final output
  • Vercel's detection fingerprint of 2 signals means your site is reliably identifiable

Choose Supabase if…

  • You need a database approach
  • You prefer traditional building tools with predictable output
  • Supabase's ecosystem and community better match your team's existing workflow
