⚡ Databases

Databases are used on websites to store and organize content, user account data, product details, and other important information, making it easy to retrieve when needed.

According to our statistics, database technologies are detected on 43.6% of all websites.
94.8% of these sites use only one database technology, 2.1% use two, and 3.1% use three or more of them.

Please note that it is not always possible to identify the database used by a website, as it is a backend technology. Also, many content management systems support multiple database types. Therefore, we only detect the database if we have sufficient confidence that it is being used.
