Sandboxie Plus and Classic share the same core components. The main difference is that the Classic UI is no longer under development, so a UI for new core functionality is only available in the SandMan UI of Sandboxie-Plus. Various other new features are also only implemented in the SandMan UI.

Many exclusive functionalities are only available to project supporters with a valid Supporter Certificate. See the table below.

Starting with version 1.11.0, there is also an Advanced Feature Pack available, which needs to be obtained in addition to a supporter certificate in order to use Sandbox Encryption, Proxy Injection, or DNS Filtering. Contributor as well as Eternal certificates include all Advanced options by default.

Please note that to use Sandboxie Plus in a commercial or educational setting, a Business Certificate is required!

* A personal type certificate once expired does not unlock features in builds compiled after it expired, builds compiled before that time retain their exclusive features unlocked state.

** Personal covers all devices you use yourself, so if you have a laptop and a desktop one certificate covers both.

*** A family pack can be used for the entire family it is not required for the family to live in the same household, so the cert can be used for children which moved out, or for your (grand) parents.

**** For as long as the service exists.
