# Parallels Browser Isolation licensing

Parallels Browser Isolation supports several types of licenses. You can purchase a license for a specific duration and number of users.

The user license is consumed dynamically when the end user signs in to the Parallels Browser Isolation User Portal to access the resources.  The license seat is persistently assigned to the named user. This provides the user with the ability to access the resources from any device. 

The differences between various types of licenses are explained below.

### Subscription

This type of license allows customers to use Parallels Browser Isolation to provide access to resources to their end users.  The maximum number of end users allowed to access resources is based on the number of user seats specified in the license and available for the duration of the contract.

The SPLA (Service Provider License Agreement) is designed for service providers and Independent Software Vendors (ISVs) offering Parallels DaaS to their customers.  It allows you to pay for licenses based on the number of seats that you make available to your customers each billing period.

### Trial

This type of license allows you to use Parallels Browser Isolation for free for a short period of time.
