epanet-js
No installs. No forced cloud storage. Just fast, local-first water modeling — powered by the engine you already trust.
You shouldn't have to choose between speed, security, and affordability just to understand your water networks.


Unlike physical rooms where you can simply walk away, digital spaces often lock users into specific environments through algorithms, subscription models, or social obligations. This forced proximity sets the stage for friction, especially when diverse viewpoints clash under the same virtual roof. The Psychology of "Sharing a Room with the Hate"
Let’s be honest—sometimes we stay because watching hate unfold is strangely compelling. It triggers our threat-detection systems, gives us adrenaline, and makes us feel morally superior. We become addicted to the very thing that harms us.

I don’t know when the hate moved in. Maybe it was always there, waiting. Maybe we invited it, one careless word at a time. Unlike physical rooms where you can simply walk
Ultimately, the phrase reflects how tightly woven our emotional lives have become with our digital habits. It highlights a culture where the act of viewing is no longer just about entertainment, but about navigating conflict, asserting identity, and surviving the friction of a highly connected, deeply divided digital world.
It doesn’t shout. It doesn’t need to. It lives in the way the mattress doesn’t creak when you turn away from me. In the cold distance between our backs. In the phone light glowing under your pillow like a tiny verdict. This public link is valid for 7 days
Consider the following design features that turn every digital room into a hate-shared space:
The "layar" portion of our keyword might hint at —the stacked, nested rooms of digital existence. In 2024 and beyond, many of us share virtual rooms with hate daily:

EPANET was a gift to the industry — free, open-source water modeling for all. But commercial vendors built on it, locked away improvements, and left the community behind.
epanet-js is our answer: a faster, simpler, affordable water modeling tool that protects your privacy and sustains the open-source future of water modeling.
We're proud to be part of the next chapter — and we're just getting started.

When you purchase more features in epanet-js, you're investing in the future of open-source EPANET development.
Our open-source model balances innovation and accessibility:
Anyone can build on our code. The two-year commercial-use delay gives us the incentive to keep pushing forward — and that fuels progress for everyone.
That means when you support us, you support more affordable hydraulic modeling software for the entire community.

You may not know this, but for decades, the U.S. EPA has given the water industry an extraordinary gift: the free and open-source hydraulic modeling software EPANET. Odds are, if you've used any commercial hydraulic modeling software today, it was built on the EPANET engine.
The problem is, instead of giving back to their open-source roots like other industries do, big-name software vendors took EPANET's open code, built private tools on top of the engine, and then locked those improvements behind patents and proprietary licenses.
Some vendors even pressured the EPA to focus only on the engine — discouraging any effort to improve the interface or user experience for everyone else.
Those vendors now charge you exorbitant prices to use their software while EPANET lags behind — and utilities, engineers, and educators with smaller budgets suffer.
We think this is backwards — and we're on a mission to change it. We're focused on creating a better experience for the entire hydraulic modeling community.
That's why we built epanet-js under an FSL license — because we want to give you an affordable, easy-to-use water modeling option that creates a sustainable future for open-source EPANET development.
Support EPANET by using software that supports it back.
Simple, quick, and useful right out of the gate — designed to open-and-go.
