Convex is a hosted backend platform combining a reactive database, serverless functions, and real-time subscriptions in one TypeScript-native product, positioned as a more integrated alternative to assembling Postgres, a queue, and WebSockets separately — popular for real-time collaborative apps. Our engine detects Convex through 2 script patterns and 2 HTML patterns tied to its client SDK's real-time connection handling. As a fully managed backend, a detection confirms a live integration with Convex's hosted infrastructure. Documented at convex.dev.
