It's built around a simple idea: you should spend your time creating, not coordinating. Agent 4 takes on the tedious-but-necessary work in the background so you can stay in creative flow and ship production-ready software 10x faster. Because Replit is where software is built, run, and shipped — all in one place — Agent 4 can handle both the complex and the mundane, so you can focus on what's uniquely human: creativity. Summary Agent 4 is built on four pillars designed to keep you in creative flow and ship production-ready apps 10X faster. - Design Freely: Generate design variants on an infinite canvas, tweak them visually, and apply the best one directly in your app. - Move Faster: Tackle auth, database, back-end functionality and front-end design all at once with parallel agents, with progress across tasks clearly visible. Once done, tasks can be merged seamlessly into the main app. - Ship Anything: Create mobile and web apps, landing pages, decks, videos and more in the same project, with shared context and design so you can scale efficiently. - Build Together: You and your team can focus on planning your app while the Agent handles all the messy coordination and execution. Submit requests in any order, and Agent 4 intelligently sequences them and executes in the best order. With Agent 3, we pushed autonomy forward. Agent could run for hours independently- self-testing, fixing issues, and driving builds ahead on its own. At the time, it set a new bar for autonomous vibe-coding agents and showed what was possible when software could move without constant oversight. That breakthrough unlocked something important: once the mechanics of building can run independently, the next frontier is creative control. With Agent
