Debugging web projects on Repl.it can be frustrating. Until today, there was no easy way to view your errors and console logs (unless you open your browsers' developer tools). But that's changing because we're introducing our new tabbed console view for environments that has graphics output (like Web and Python Turtle).

Introducing Agent 4 — our fastest, most versatile Agent yet. 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.
For years, building a mobile app has required specialized knowledge, complex toolchains, and expensive hardware. If you weren’t a seasoned mobile developer—or didn’t have one on your team—getting from idea to App Store could feel impossible. Today, that changes. We’re excited to introduce Mobile Apps on Replit: a new way to go from idea to fully published app using nothing more than natural language. No native development experience required. No complex setup.
You draft the PRD. Stakeholders align. Then you wait weeks for development. By the time you see a prototype, requirements have shifted and edge cases emerge. What if your spec became a working app immediately? Product Managers Are Natural Vibe Coders Replit CEO Amjad Masad noted on a recent Reid Hoffman podcast that product managers are some of the best vibe coders. Why? PMs break problems into clear steps and communicate precisely—exactly what AI needs to build effectively. You already know what to build. Replit Agent makes it real.
