MaximaLabs vs ChemCAD
The same steady-state rigor, in a browser — with an AI copilot, live collaboration, and usage-based pricing instead of a desktop install and a per-seat license.
ChemCAD (Chemstations) is a capable, well-regarded steady-state simulator with a long track record, and it is deliberately priced below Aspen — it is the pragmatic choice for many consultancies and mid-size plants. It is also Windows-desktop software, licensed per seat, with capability split across modules (CC-THERM for exchangers, CC-DYNAMICS for transients). MaximaLabs targets the delivery model rather than the numerics: the same class of steady-state work, reachable from any browser, with the copilot, sharing, and cost model that a desktop tool cannot offer.
An honest comparison
- A long, established validation record and a loyal installed base that trusts its results
- Mature, well-documented unit models with decades of real project use behind them
- Works fully offline — no network dependency, which some plant environments require
- Priced well below the Aspen tier, so the cost argument against it is much weaker
- Runs in any browser — nothing to install, and nothing pinned to one Windows machine
- AI copilot builds flowsheets from a description and explains convergence failures in plain English
- Live multiplayer and share links instead of passing model files around
- Exchanger rating, costing, relief sizing and sustainability accounting sit in the same flowsheet rather than in separate modules
- Usage-based pricing instead of a per-seat license, and a Python SDK plus an Excel add-in for automation
The honest positioning
Being straight about the wedge is the point.
