Quimb vs SynxFlow
Both stand on physics simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
Choose Quimb if you need a free Python library centered on tensor-network work or quantum information calculations. Its documented setup requires Python 3.11 or newer, and the optional acceleration route involves additional packages and MPI dependencies.
