One or more techniques and/or systems are disclosed for providing recommendations for an add-on to a base program operating on a computing device, thus allowing a user to make a more informed decision as to whether to allow the add-on to be installed or not. To make the recommendation, collection software is queried for information about an add-on when installation or instantiation of the add-on is detected on the computing device. Information about the add-on is collected by the collection software, which comprises one or more add-on detection programs. A recommendation for applying the add-on (or not) is generated using the collected information, where the recommendation comprises a ranking based on detection program prioritization.
