Add-on vs. Plug-in

Key Differences

Add-ons are additional components or software that enhance or extend the functionality of a primary application, usually providing new features or capabilities. Plug-ins, on the other hand, are specific types of add-ons that are designed to integrate seamlessly into a host program, extending its functionality without altering its core structure.

While add-ons can be standalone applications that work in conjunction with a primary program, plug-ins are always dependent on the host application and are designed to work within its environment. Add-ons enhance the overall experience, whereas plug-ins provide specific, often technical, functionalities.
