A hackathon (also known as a hack day, hackfest or codefest) is a design sprint-like event in which computer programmers of collaborate intensively on software projects. The goal of a hackathon is to create usable software or hardware with the goal of creating a functioning product by the end of the event. Hackathons tend to have a specific focus, which can include the programming language used, the operating system, an application, an API, or the subject and the demographic group of the programmers. In other cases, there is no restriction on the type of software being created.
