Our review
Pros	Predicts solubility across liquids, solids and gases Covers phase equilibria, partitioning, vapor pressure and pKa Offers graphical workflows and command-line batch processing	Free of charge, with voluntary donations rather than a paid plan Combines thermodynamic packages, compound data and reaction numerics Supports third-party CAPE-OPEN components in flowsheets
Cons	Windows desktop deployment limits platform flexibility Contact-sales pricing makes cost assessment less direct Specialized thermodynamics scope is narrower than process simulation	Windows desktop software, with no mobile access Focused on process simulation, not chemical inventory or SDS management Community support may not suit teams needing other support channels
Our verdict	BIOVIA COSMOtherm applies COSMO-RS to predict thermodynamic properties of molecules in pure and mixed liquids. Its intended audience includes researchers and teams in chemistry, chemical engineering, formulation, drug development,… Read the review →	COCO Simulator is a Windows-based environment for steady-state chemical process simulation. Its COFE graphical flowsheeting environment works with TEA thermodynamic property calculations, COUSCOUS unit operations and CORN reaction… Read the review →
