About epanet-js
epanet-js runs the real EPANET engine compiled to WebAssembly, wrapped in a modern map-based interface: import an INP model or draw one on satellite imagery, run extended-period simulations, and inspect pressures and flows — all in a browser tab. The underlying open-source library (the epanet-js engine bindings) is MIT-licensed and usable in your own JavaScript projects.
For quick model checks, teaching, fire-flow spot analyses and utilities without modelling software budgets, it removes every setup barrier. The hosted app follows a freemium model with team features on paid plans.
