For example - there are client-server applications. The application of this type runs on one machine (client) and conntects to another machine (server) in order to work. What can I call an application that to work only needs one machine?

  • Locally installed.

    ‘Antonym’ is a dangerously fickle word. I would say the antonym of a ‘client-server’ application would be a server-client application: one that’s installed on the server, but needs to connect to a client machine to work (similar to how most web apps or browser-based apps work).

    @JanusBahsJacquet Or a peer–peer program, or a non-networked program, amongst others. Pick your favorite axis.

    I agree with @JanusBahsJacquet, antonym means the semantic opposite of a word. In case the word is not an (obvious) member of a dialectical pair like left, right, such a semantic opposite may be a tricky thing to ask for: What would be the "antonym" for "black-currant tea"? Strawberry coffee? There are tens, if not hundreds of common application architectures, of which client-server is just one. Assuming that there is an exact opposite architecture is very much like assuming a specific tea flavour has an opposite.

    @oerkelens Strawberry coffee sounds absolutely godawful. Nov 24, 2014 at 18:28

That would be a "standalone" application.

Word processing works in a standalone manner, while email requires a client-server organization.


You can either call it a Standalone Application or a Thick Client Application.

An application that does not require any network connectivity, is usually called a Standalone Application. While an application, that does not require a connection to a server system in order to run, is called a Thick Client (NOTE: these applications can use a connection to a server for some of the features, but unlike a Thin Client, these do not entirely depend on the server). These terms are loosely in the tech industry.


  • Thick clients: MS word, Video games, Acrobat Reader, Web browser, etc.
  • Thin clients: Websites, Mobile applications, Email clients, etc.
