epanet-js is built for everyone who works with water networks — from utilities running the system every day to students learning the craft. Find your fit.

A utility operator, a consultant on a deadline, a professor in a computer lab, and an engineer designing a community supply are doing very different work. What they share is the need to get to a trustworthy model quickly, keep their data in their hands, and not have the software get in the way.
That's what epanet-js is built for. The same tool serves all of them because it's fast to a working model, local-first, runs anywhere, and is built on the EPANET engine the whole industry already trusts.
Whatever you do with the network, you get from data to a running model in minutes, not weeks.
Local-first by default. Your network — or your client's — stays on your machine unless you choose otherwise.
The same trusted engine the industry runs, so skills and models carry across teams and tools.
A free tier, free for education, fair per-seat pricing, and source that's public from day one and fully open after two years.
