Psi Lambda LLC | Parallel computing made practical.


You already have a Kappa framework free license. Language bindings and keywords and examples for .Net (C# and Visual Basic), Perl, Python, Ruby, Lua, Java, etc, are no additional cost. Psi Lambda LLC’s policy is to not charge for new versions of the Kappa framework even if the versions include major new features. Maintenance fixes are provided for free. Kappa framework licenses function for all Kappa platforms. Here are the prices for all of the Kappa framework software license keys:

New license–effective immediately and shipped with version 1.3 and later

Attachment A of the License has been modified to be more permissive. Specifically, it allows for developing with the Kappa framework and redistributing the Kappa framework components (but not the Software License Key(s)) with your application without upgrading to a Developer License. Under this arrangement your customers would buy the Software License Key(s). Use the contact form below if you wish to communicate about licensing possibilities.

The only change to the License.txt is the following replacement for Attachment A:
