I'm building epanet-js[0], a local-first web application for simulating water network.

The goal is to replace clunky, expensive enterprise desktop tools (which often charge $10k+ for a wrapped version of the open-source US EPA engine). We want our version to be frictionless: login optional, runs entirely in the browser, and saves files locally to your device.

We are using the Functional Source License (FSL) to keep it sustainable while remaining open.
