The expression is “a feature, not a bug.” We use this expression to describe something that seems like a flaw, but is in fact intentional. A flaw is a mistake or a disadvantage.

Can a bug be a feature?

A feature is a functionality intended to be useful to the user. A bug is a behavior, usually the result of an error or sloppy programming, that gets in the way of the features. Antifeatures, unlike features, are not useful from the standpoint of the software user.

What is the difference between a feature and a bug?

A bug is a failure to conform to reasonable expectations based on requirements and norms. A feature is a unit of functionality that is requested as a requirement or change request.
