MaximaLabs
First-principles & equation-oriented modeling

MaximaLabs vs gPROMS

Equation-oriented and custom-equation modeling in the browser, with an AI copilot — accessible first-principles modeling without the desktop or the price.

gPROMS (Siemens / PSE) is the gold standard for rigorous first-principles, equation-oriented, and custom DAE modeling — deep, powerful, and expensive. MaximaLabs offers an equation-oriented simultaneous solver and a custom-equation engine in the browser, with an AI copilot and collaboration, at screening-to-intermediate fidelity for a fraction of the cost.

An honest comparison

Where gPROMS is genuinely stronger
  • Deep, rigorous first-principles DAE modeling and advanced custom-model development
  • Established gPROMS FormulatedProducts / model libraries and validation heritage
Where MaximaLabs wins
  • Equation-oriented simultaneous solver + a custom-equation engine, in any browser
  • AI copilot to build models and explain failures; live collaboration; usage pricing
  • One unified model across simulation, digital twin, and APC — no export/re-import

The honest positioning

Being straight about the wedge is the point.

MaximaLabs makes equation-oriented and custom-equation modeling accessible and collaborative — strongest for teams who want browser-based, AI-assisted modeling without a gPROMS-scale license, not a replacement for its deepest rigorous-DAE and advanced-model-development work.
