Pricing

Modex is free to use

Modex Desktop and the Modex extension are free to download and use, with no account, no sign-in, and nothing to activate. If we introduce paid features or plans later, we will describe the terms and pricing clearly before you are charged.

What free includes.

Every feature

Modeling, local simulation, results, plots, figures, and documents. There is no reduced edition and nothing held behind an upgrade.

Nothing counted

No cap on models, simulation runs, projects, or machines, and no per-seat licence to buy or renew.

An open-source solver

Modex runs simulations with the open-source OpenModelica compiler, so there is no separate simulation licence.

AI billed by your provider

Connect your own provider account. Requests go from the app straight to it, so there is nothing for us to meter and nothing added on top.
