What is a desktop application?

A desktop application is software installed and run on a computer rather than delivered only through a web page. It can use native operating-system APIs, local files, notifications, hardware, and offline storage. Examples include editors, media players, and development tools.

“Desktop” does not guarantee native code: Electron and other frameworks can package web technologies into a desktop app. Likewise, a desktop app may still require an internet connection for accounts, synchronization, licensing, or remote data.

When choosing one, compare update behavior, permissions, offline needs, supported operating systems, file access, accessibility, and how the vendor handles data. Install software from a trusted publisher, keep it updated, and review whether it starts background services. A web app may be easier to deploy across devices; a desktop app may provide deeper integration. The right choice is about the product's requirements, not a blanket claim that one is always faster.
