Alternatives

There are quite a few Java class file shrinkers, optimizers, obfuscators, and preverifiers out there. Users of ProGuard tell me it easily compares with the best of them. However, you may want to check that out yourself.

This is a list of the programs of which I'm aware. Obviously, I've never personally tested all of them. Many programs, even commercial ones, have been abandoned. Please drop me a note if you know of any other shrinkers, optimizers, obfuscators, or preverifiers, or if some information provided below is incorrect.
