QMCF2 is a molecular-simulation package for molecular dynamics, Monte Carlo, geometry optimization, molecular mechanics, and combined quantum-mechanical/molecular-mechanical calculations. The source includes force-field, electrostatics, constraints, thermostats, pressure control, water models, QMCF/QM-MM, external-QM interfaces, conversion tools, and analysis utilities. Interfaces are available for xTB, DFTB+, Gaussian, Turbomole, CRYSTAL, and ASE-based workflows. External programs must be installed separately. ...

QMForge reads output from various quantum mechanical calculations and provides tools for analyzing these results. Specifically, population (Mulliken and C-squared), fragment, and charge decomposition analyses are available. See https://qmforge.net for more info.

ParamIT is a toolkit aiding the development of molecular mechanical force field parameterization of small, drag like, molecules within CHARMM general force field (CGenFF) protocol. The developed toolkit helps the researchers in following ways: 1) automating the creation of multiple input files for quantum and molecular mechanics programs, 2) automating the output analysis and 3) substitute the use of full MM programs with a faster specialized one.
