Many different types of software licenses exist. The types of licenses available are generally categorized by their intended use and volume. Examples of software license types Evaluation license: A limited-time or limited-use license that is intended to be used to provide the user with a demonstration of the product before purchasing. Concurrent license: A license that can be shared by a designated number of multiple users simultaneously. For example, if you have 6 concurrent licenses you can have up to 6 users operating the software simultaneously; the seventh simultaneous user would not be permitted to use the software. This is also known as a floating license. Perpetual license: This license type grants access to the current version of the software for a one-time purchase.  Subscription license: This type of license grants access to the software for a monthly or annual fee. This fee is typically based on the amount of users. Named user license: A license that is intended for use by a specific individual user. Proprietary: The creator of the software reserves all rights to the product. This type of license often includes stipulations that prohibit its modification or redistribution. Free and open-source software (FOSS): A software license that gives the user unlimited rights to modify and reuse the software’s code.
