Replit Agent 4

Replit just dropped Agent 4, and the pitch is wild: build, design, and ship an entire project in one AI-powered flow. That’s not a small upgrade — that’s a complete rethink of how we get from idea to working product without the usual five-tab shuffle and thirty Slack threads. If they’ve actually nailed the “one flow” thing, this changes the game for founders who need to move fast and can’t afford to wait on designers or deal with developer scope creep. I’m skeptical until I see it ship real projects, but the ambition here is unmissable — and Replit’s been around long enough to earn at least that much attention.
