The Indexed Database API (commonly referred to as IndexedDB) is a JavaScript application programming interface (API) provided by web browsers for managing a NoSQL database of objects. It is a standard maintained by the World Wide Web Consortium (W3C).

As an alternative to the Web storage standard, IndexedDB can provide more storage capacity. Web storage has fixed limits per website, but IndexedDB limits are "usually quite large, if they exist at all".

Use cases for IndexedDB include caching web application data for offline availability. Some browser modules, such as devtools or extensions, may also use it for storage.
