Best for Statisticians, academic researchers, and analytics engineers doing custom statistical modeling and visualization. Quantitative researchers and engineers needing high-performance statistical simulation without dropping to C. Python-based analysts and econometricians who need rigorous statistical inference, not just predictive accuracy. Python developers who need numerical and statistical primitives underneath higher-level analytics tools.
Pricing

Free and open source; no paid tiers for the language itself. Commercial support and hosted environments are sold separately by third parties (e.g. Posit).

Pricing has not been verified yet — see the vendor's site.

Free and open source under the MIT license; JuliaHub sells separate paid cloud and enterprise services built on top of the language.
