About

OpenDatabase fingerprinting detects deprecated WebSQL API via window.openDatabase. While removed from modern browsers, Safari and older Chrome/Android browsers still support it. Presence indicates Safari (most likely) or older browser versions. WebSQL was deprecated in 2010 but Safari continues supporting it for legacy compatibility. This makes it a strong Safari identifier and mobile Safari detector. Testing openDatabase availability alongside other deprecated APIs creates a browser vintage profile. Modern browsers return undefined, creating a binary signal.

Use Cases

•Safari detection
•Legacy API support
•Browser age
•Mobile Safari identification
