NMRInversions.jl vs Polychem

Both stand on chemistry simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

NMRInversions.jl

Free plan Linux

NMRInversions.jl offers an accessible workflow for NMR inversion, correction, fitting, and visualization. Its Linux availability and stated harmonic-inversion limitation define where it fits.
