🎉 Slopfest #99 is live: Vibe Coded →The world’s first AI-native, agent-first, vibe-driven slop festival. 99 editions. Zero lines read. An engineer coined 'vibe coding', where you forget the code even exists. We have been forgetting since 1927.

The website, ticketing, lighting and bar menu were all generated from a single prompt, 'make it good', and nobody on the committee read a line of the result. It mostly worked. The bar served only Almdudler, for reasons nobody can find, and the Blechkopf, now with an API, raffled itself off and has not yet come back.
Slopfest has taken place in Vienna since 1927. This is iteration 99. The agent says it is the best one yet. The agent says that every time.
Nine features. One icon. Zero regrets.
Every piece of slop is generated, regenerated and re-regenerated by state-of-the-art AI. Quantity over quality, at scale.
Build a full-stack app in four minutes without reading a single line. Accept all. Ship. Pray. Repeat.
Walk in as yourself, walk out as a hand-painted anime still. Works on people, dogs, the Stephansdom and your Schnitzel.
Live appearances by Tralalero Tralala, Ballerina Cappuccina and Brr Brr Patapim. Nobody knows what they mean. That is the point.
An agent orders the food. Last year it ordered 4,000 Wiener Schnitzel and one (1) salad. We ate all of it.
SOC 2 compliant vibes, probably. We asked the agent and it said yes with a lot of confidence.

Our context window is so large we forgot what this card was supposed to be about.
Describe the slop you want. Typos are fine. The AI knows what you meant (it does not).
Click “Accept all” on 3,000 changes without scrolling. Scrolling is for engineers.
Deploy straight to production on a Friday night. What could go wrong? Everything. It’s fine.
Italian brainrot’s finest, confirmed by an AI with 99% confidence.

“AI slop” is now a phrase your aunt uses at dinner.
In 2025 the term went mainstream: newspapers, dictionaries, the family group chat. We have been saying it since 1927 and accept royalties in tokens.
“I vibe-coded a dating app for Italian brainrot characters during the keynote. It has 40,000 users. I don’t know how it works.”
“The AI said my Ghibli portrait was absolutely stunning. It says that to everyone. I have never felt more seen.”
“Programs must be written for people to read, and only incidentally for machines to execute.”

* All plans are the same event. Prices exclude VAT. There is no VAT on €0. We checked with the agent.
Yes. The Pro plan is also free. The Enterprise plan is free too, but you have to have a meeting about it.
An agent, in about four minutes. A human pressed Enter and went to get a Melange. Nobody has read the code and we intend to keep it that way.
That is not an error, that is a feature. We asked the agent to fix it. It said “You’re absolutely right!” and moved it slightly to the left.
You describe what you want, the AI writes it, you accept everything and never look. The term is from early 2025. Slopfest has practised it since 1927, by pneumatic tube.
Yes.
He has confirmed. He was also confirmed by an AI, so treat it as a strong maybe.
