Crippleware

Encyclopedia : C : CR : CRI : Crippleware

Crippleware is a form of shareware. It is a term of distinction used to differentiate between types of shareware software. As can be inferred from the name, it is generally not held in high regard. Other types of shareware include nagware, demoware, freeware, adware, and even spyware.

Crippleware programs are free versions of computer programs that lack the most advanced or in some cases even crucial features of the original program. One of the canonical examples of crippleware is a word processor that cannot save or print. Crippleware versions are made available in order to increase the popularity of the full program without giving it away for free.

The authors of crippleware defend the practice by noting that regular shareware versions are often cracked, so that the authors are not paid for their work. Users who dislike crippleware argue that they cannot test the program under real life conditions and therefore do not know whether it will truly meet their needs.

Nagware may be a less obstructive way to encourage registration of shared software, but this type of software can still be modified to disable the nagging feature. This is also often possible with crippleware software that can be "unlocked" into a fully-functional version of the software via a serial number, however. For this reason, most companies that are serious about crippleware have a separate trial version of the program that does not even include the code for the disabled features. Only users who have bought a license are given access to the fully-functional version of the program.
