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.
PlanetScale is a serverless MySQL platform built on Vitess (the database-sharding technology originally built at YouTube), offering non-blocking schema migrations via database branching — used by teams that want MySQL's ecosystem compatibility with a modern, horizontally scalable managed backend. Our engine detects PlanetScale through 1 script pattern and 1 HTML pattern tied to its client-tooling conventions; like most managed databases its footprint is primarily backend-side with minimal front-end signal. Documented at planetscale.com.
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.
