No installs. No forced cloud storage. Just fast, local-first water modeling — powered by the engine you already trust.

The EPANET user's dilemma

  • Classic EPANET is powerful — but clunky and outdated. Workarounds become your workflow — slow and cumbersome.
  • Big-name platforms look polished, but they're overpriced and bloated with features you don't need to analyze your network quickly.
  • Modern browser-based tools exist — but they force your data into the cloud, raising privacy and compliance concerns. Plus, they offer little for those doing long-term planning and analysis.

You shouldn't have to choose between speed, security, and affordability just to understand your water networks.

When adopts the aesthetics of news—serious music, authoritative graphics—viewers trust it implicitly. This has led to a reality where a significant portion of the population sources their political beliefs from Marvel movies or late-night monologues. The danger is not the content itself, but the lack of media literacy required to distinguish fact from narrative.

The intersection of entertainment content and popular media remains one of the most dynamic sectors of human ingenuity. As technology advances, the ways stories are told, distributed, and monetized will continue to redefine the human experience.

Modern entertainment manifests across several distinct, yet highly integrated verticals:

Today, platform algorithms actively curate the consumer experience. Streaming services and social media platforms analyze user behavior in real time to feed an endless scroll of personalized content. The consumer no longer just chooses the media; the media actively predicts and shapes the consumer’s desires. The Mechanics of Modern Entertainment Content

In recent years, the way we consume entertainment content has undergone a significant shift. The rise of streaming services such as Netflix, Hulu, and Amazon Prime has revolutionized the way we watch movies and television shows. These platforms have made it possible for us to access a vast library of content from anywhere in the world, at any time. This has led to a decline in traditional television viewing and a shift towards on-demand content.

The trailing xoxxx1 mixes the common abbreviation "xoxo" (hugs and kisses) with extra "x" characters and a final "1". In digital communication, "xoxo" conveys affection or lightheartedness. Here, it may serve as:

The trajectory of popular media points toward an increasingly automated and decentralized future. Artificial intelligence tools now generate scripts, compose musical scores, and render complex visual effects autonomously. The intersection of entertainment content and popular media

The rise of the internet and cable television shattered this uniformity. Audiences fractured into niche communities. Content choice expanded exponentially, allowing individuals to seek out specialized material that aligned precisely with their specific interests.

EPANET deserves better — and so do you.

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 support epanet-js, you support EPANET.

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.

Simple, transparent pricing for every kind of modeler.

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.
