Web SQL Database is a deprecated web browser API specification for storing data in databases that can be queried using SQL variant.[1][2] The technology was only ever implemented in Blink-based browsers like Google Chrome and the new Microsoft Edge, and WebKit-based browsers like Safari. As of February 2024[update], WebSQL is being phased out in favor of WebStorage and IndexedDB and OPFS, but still available in some contexts under restrictive conditions.
