CoolProp alternatives
The best CoolProp alternatives in software development tools, ranked by Sparkpulse's velocity_score.
Updated Aug 12, 2026
Looking for the best alternatives to CoolProp? Sparkpulse tracks and ranks 12 alternatives in software development tools by shipping velocity — how frequently each ships meaningful updates, verified from official changelogs. For reference, CoolProp shipped 0 meaningful updates in the last 30 days and carries a velocity score of 0.0 out of 10 in 2026. The alternatives below are ranked the same way, so you're comparing real release momentum, not marketing claims.
About CoolProp
CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.
CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.
