Codes built with Kranc have been used in 16 publications, mostly in the area of Numerical Relativity for simulating black holes.

Some Kranc-based codes are:

- the Penn State/Georgia Tech Einstein equation code for 3D binary black hole simulations;
- McLachlan - the 3D Einstein equation code in the Einstein Toolkit (free software);
- WeylScal4 - the gravitational wave code in the Einstein Toolkit (free software).

Kranc is also used for experiments with vectorisation in the Blue Waters project.

Kranc has been used at

- the Numerical Relativity group of the Albert Einstein Institute;
- the Center for Computation and Technology at Louisiana State University;
- the Applied Mathematics Department of the University of Southampton;
- the Center for Gravitational Wave Physics at Pennsylvania State University;
- the Center for Relativistic Astrophysics at Georgia Institute of Technology
- the Relativity and Gravitation group at the University of the Balearic Islands;
