Community Buzz
Replit agent 4 is just insane. In 2 hours I built my whole clinic stack all with the same design language. Full clinic landing page, booking platform functioning! FULL iOS app for patient biomarkers.
My girlfriend said she wanted to build an app so I bought a one year subscription to Replit for her. She was blown away when we had a basic concept online with Replit Agent within 15 minutes.
I just built an AI-Powered GitHub PR review application using just prompt with @Replit Agent 3. And thats it, I got a fully working AI Powered Github review application ready.
More progress on my photo app built with the new @Replit mobile stack. I wrote zero code. All Replit Agent.
So @Replit Agent 4 just built my web app, a mobile version, and my launch slides all at the same time. You can run multiple agents in parallel, so while one architects the backend, another designs the frontend, and a third sets up your database.
