...MESMER allows you to simulate systems over a wide range of pressures and temperatures, extract rate coefficients, analyze experimental data, fit model parameters and represent rate coefficients in formats that can be used directly in large scale simulations (e.g. Cantera or Chemkin).
Cantera is a suite of object-oriented software tools for problems involving chemical kinetics, thermodynamics, and/or transport processes. It can be used from MATLAB, Python, C++, or Fortran.
sct-cantera is an object oriented MATLAB toolbox that allows the creation and manipulation of chemical states (IdealGasMix or PureSubstance). sct-cantera uses Cantera in the background to do the calculations. ( Cantera is available on sourceforge).
