epanet-js is a new web-based tool that runs hydraulic simulations for water utility systems using a browser and WebAssembly, offering a modern alternative to costly legacy software.

Why it matters: It dramatically reduces costs and improves accessibility by replacing $16,000/year Windows-only software with a browser-based solution.

The big picture: Combines open source roots with industry expertise to modernize hydraulic modeling software and expand market reach.

The other side: Uses a Functional Source License transitioning to MIT after two years, balancing open source ideals with sustainable funding.

Commenters say: Users praise the innovation and affordability, discuss licensing nuances, and explore broader applications like irrigation and gaming simulations.
