Vibe Coding with Replit Agent 4
What an afternoon. Ideas became apps, strangers became collaborators, and Agent 4 did not disappoint.
This event has now ended
Our Replit Agent 4 mini-hackathon on April 26th was a blast. We had builders of all skill levels show up, fire up Agent 4, and ship real things in a single afternoon.
Whether you were there or missed it, the resources below are still worth a look. And if you want to be part of the next one, come join the community.
What is Replit & Vibe Coding?
Replit is a platform where anyone — coder or not — can build and deploy real apps straight from their browser. Agent 4 is their latest AI that turns plain English into fully working software. Vibe coding is exactly what it sounds like: you describe the vibe, the AI writes the code. No terminal. No setup. Just ideas becoming real things.
