Rather than relying solely on expensive wet-lab experiments, scientists can now perform accurate quantum mechanical calculations on everything from small organic molecules to enzyme active sites — all from a Linux workstation or HPC cluster. Three open-source engines dominate the Python-accessible landscape: <strong>PySCF</strong>, <strong>Psi4</strong>, and <strong>NWChem</strong>.</p>
