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.


Ultimately, both Fairy Tail and One Piece are must-watch series for fans of anime and manga, and their availability on official streaming services or unblocked platforms has made it easier for audiences to enjoy these iconic series. As the anime and manga industries continue to evolve, it will be interesting to see how these series adapt and continue to captivate audiences worldwide.
If we had to declare a winner, One Piece might have a slight edge due to its vast and diverse world-building, complex characters, and epic story arcs. However, Fairy Tail's magical and fantastical elements, coupled with its focus on friendship and camaraderie, make it a beloved series in its own right.
Fairy Tail and One Piece convey various themes and messages that resonate with their audiences. Fairy Tail emphasizes the importance of friendship, teamwork, and believing in oneself, while One Piece promotes themes of adventure, perseverance, and the power of dreams. Both series also tackle darker themes, such as the consequences of war, the dangers of corruption, and the value of sacrifice.
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.
