What is the difference of plugin, add-in and add-on?

For example, if you are looking for a Microsoft Office Add-In, an Add-In for Outlook or any other add-in for Microsoft software, you will often come across terms such as Plugin, for example Outlook Plugin, or Add-Ons, for example Microsoft Teams Add-Ons. But what is the difference between Plugin, Add-In and Add-On and what has it got to do with the the spelling of plug-in, add-in and add-on?

Add-In Definition

First of all, the definition of an add-in: Add-ins are small computer programs - also called mini-applications - that are integrated in a a larger computer program (main application), for which the add-ins were Add-Ins were specifically developed, additional functions provide (extensions) or integrate certain services or tools (integrations). (integrations). Such add-ins are developed by the manufacturer of the main program itself or by third-party providers. An add-in is usually not included in the included in the standard delivery of the main software, but can be be added to the main software by the user or administrator. added to it by the user or administrator.

Add-ins do not normally function independently, i.e. without the main software. normally do not work. The installation of an add-in takes place on computer (for example, on a desktop), on a server or in the cloud. server or in the cloud. There are both free and paid paid add-ins.

Meaning of add-ins

And what is the meaning of add-ins, if you had to translate this term translate this term? The term "add" comes from the English language and means "to add". The English term "in" also means "in" in German "in". So basically it is an "addition in something", in this case the addition of an additional additional software in a main program.


The terms plug-in, add-on, app, extension, and integration are are or were often used synonymously with the term add-in. The software development company Microsoft initially used the term "apps for Office" for its Office extensions, for example initially used the term "Apps for Office", for example in Outlook 2013. Since Outlook 2016, so also in Outlook 2019, Outlook 2021, Outlook for Office 365 and Outlook for Microsoft 365, Microsoft calls these Microsoft calls these extensions "Office add-ins". The reason for this name change is that Microsoft uses the term "Office apps" for the downloadable versions of its programs such as Excel, Word, Outlook or PowerPoint, for example, from Apple's App Store, from the Google Play Store or from the Microsoft Store.


As for the spelling of the names of these tools, you will sometimes find the versions with a hyphen, i.e. plug-in, add-on and add-in, but also the versions without hyphen without hyphen: Plugin, Addon and Addin. In addition one can say, that the hyphenated spelling is actually the original spelling. is the original spelling, but the hyphen is abandoned with the is abandoned with time, Outlook Add-Ins then become Outlook Addins. In addition in particular with Microsoft the hyphenated spelling of the two words connected by the hyphen is capitalized. words connected by this hyphen are written in capital letters, so Plug-In instead of Plug-in, Add-In instead of Add-in and Add-On instead of add-on.

Furthermore you can install Add-Ins by executing an installation file, as is the case with the Gangl Add-Ins, which are which are available for download as a file from the Gangl website or on download from the Gangl website or are provided on request via a download link. upon request.
