Web SQL Database

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 API is supported by Google Chrome,[3] Opera,[4] Microsoft Edge,[5] and the Android Browser, albeit support is slowly being phased out.[6] Web SQL was deprecated and removed for third-party contexts in Chromium 97. Web SQL access in insecure contexts is deprecated as of Chromium 105 at which time a warning message will be shown in the Chrome DevTools Issue panel.

The W3C Web Applications Working Group ceased working on the specification in November 2010, citing a lack of independent implementations (i.e. using database system other than SQLite as the backend) as the reason the specification could not move forward to become a W3C Recommendation.[1]

Mozilla Corporation was one of the major voices behind the break-up of negotiations and deprecation of the standard, while at the same time being the main proponents behind an 'alternative storage' standard, IndexedDB.[7][8] Mozilla's argument against it becoming a standard was because it would codify the quirks of SQLite.[9][10]
