This new viral one-man online rave has multiplayer, no login, no ads, and no catch

A small website went viral on Sunday (May 31) and briefly brought a corner of the internet together on a shared dance floor — before the server buckled under the crowd.
Hallucinate, at hallucinate.site, is exactly what it sounds like: a massively multiplayer online rave. When you open the site, you're dropped into a low-poly 3D club, surrounded by real users dancing to a looping DJ set sourcing videos from YouTube. There's no account, no password, and no ads involved.

The project was shared to Hacker News today by its creator (a developer going by stagas), racking up a decent number of upvotes and comments within hours. A parallel Reddit post on r/InternetIsBeautiful summed it up nicely with the caption: "The internet is healing."

Under the hood, it's more fun than it looks. Stagas built it with a dead-reckoning, client-authoritative architecture that syncs only key state changes — keeping things smooth across hundreds of players without hammering the server. The full source is on GitHub under an MIT licence, and contributions are openly welcomed.

The launch didn't go entirely smoothly, though. Hallucinate got hugged to death by Hacker News traffic within the first hour. The website went down before being patched and restarted in near-real time — all while its creator was simultaneously responding to bug reports, fielding feature requests, and manually banning IP addresses after bad actors hit the open chat. "They keep coming back with different IPs," stagas wrote, mid-thread.

Feature requests kept pouring in anyway: jumping, skin colour options, mobile controls, a live player count. The creator's response to most of them? "PR will be accepted."
