Croquet Project has not been under active development. All further development of the technology has occurred under the Open Cobalt effort. Croquet is a software development kit (SDK) for use in developing collaborative virtual world applications.

The technology is designed to facilitate such replication between peers, to greatly reduce the overhead needed for widespread deployment of collaborative virtual worlds. This efficiency, combined with
