Head to head

MaximaLabs vs Aspen Plus

The same rigorous steady-state simulation — in the browser, with an AI copilot, at a tenth of the price.

Aspen Plus is the industry benchmark, and the industry benchmark for cost, install friction, and a 3-day learning curve. MaximaLabs runs the same rigorous thermodynamics and unit-op library in any browser, explains failed solves in plain English, and prices by usage instead of six-figure seat licenses.
