Octave is a computer program for performing numerical computations which is mostly compatible with MATLAB . It is part of the GNU Project. It is free software under the terms of the GNU General Public License.

GAP is described as 'System for computational discrete algebra, with particular emphasis on Computational Group Theory. GAP provides a programming language, a library of thousands of functions implementing algebraic algorithms written in the GAP language as well as large data libraries of' and is an app. There are more than 10 alternatives to GAP for a variety of platforms, including Windows, Linux, Mac, Web-based and Android apps. The best GAP alternative is GNU Octave, which is both free and Open Source. Other great apps like GAP are SageMath, Mathematica, MATLAB and Maxima.
