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.


Atta took a different route. He built a family dynasty. With over 30 million subscribers, his "Gen Halilintar" series turned daily sibling squabbles and luxury car purchases into must-watch episodic content. He bridged the gap between old media (television) and new media by hosting major award shows while simultaneously live-streaming from his gaming chair.
These creators changed the definition of Indonesian entertainment. It is no longer passive; it is participatory. Fans don't just watch; they comment, they recreate dances, and they defend their favorite creators in online battalions.
Indonesia has one of the largest mobile gaming populations in the world, dominated by Mobile Legends: Bang Bang and PUBG Mobile. The entertainment isn't just the game play; it is the personalities. smp indo bokep 2021
Streamers like Jess No Limit and Brando (Windah Basudara) are rock stars. Their live streams generate popular videos that are clipped and re-shared constantly. The specific Indonesian style of "toxic positivity"—yelling at teammates but saying "Sorry, sorry, my bad" two seconds later—has become a meme template used across Asia.
These gaming videos also drive massive economic activity. "Top Up" (in-game currency purchase) videos, where streamers spend hundreds of dollars pulling for rare skins, are a genre unto themselves. Viewers live vicariously through the dopamine hit of the "pull." Atta took a different route
Ria Ricis (now Ricis) pioneered the extreme challenge vlog. Her content—ranging from living in a house full of snakes to executing elaborate pranks on her family—standardized high-energy editing. Her wedding alone generated billions of views across short clips, proving that personal life events in Indonesia are treated like major sporting events.
| Creator | Niche | Vibe | |---------|-------|-------| | Atta Halilintar | Family vlogs, challenges | High-energy, mainstream | | Ria Ricis | Humorous daily life | Relatable, dramatic | | Baim Paula | Pranks & social experiments | Wholesome + chaotic | | Jess No Limit | Gaming (Minecraft, GTA) | Fast-paced, young male audience | | Nihongo Mantappu | Language/culture (Japanese-Indonesian) | Educational + funny | | Raditya Dika | Short comedy skits | Deadpan, observational | He bridged the gap between old media (television)
Jess No Limit and MiawAug lead Minecraft and mobile game content, often with high-energy commentary.
The last three years have seen a seismic shift from long-form vlogs to short-form chaos. The popular video format now is 60 seconds or less. Indonesian creators have mastered the "micro-drama."
Look at the rise of Konten Warjul (Jakarta-Style Slang Content). Creators like Fiki Naki use rapid-fire Betawi dialogue to create relatable skits about office life, motorcycle gangs (geng motor), and street food vendors. These videos are raw. There is no fancy lighting. Often, they are shot on a phone in a cramped warung (street stall). Yet, they garner tens of millions of views.
Why? Authenticity. In a world of polished K-Pop idols, the roughness of Indonesian popular videos feels like hanging out with a funny friend. The use of bahasa gaul (colloquial Indonesian) mixed with regional languages like Javanese or Sundanese creates a linguistic playground that algorithms love because engagement (comments asking "What does that word mean?") is high.

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.
