Introducing Agent 3: Our Most Autonomous Agent Yet

We’re excited to introduce Agent 3—our most advanced and autonomous Agent yet. Compared to Agent V2, it is a major leap forward. It is 10x more autonomous, with the ability to periodically test your app in the browser and automatically fix issues using our proprietary testing system—3x faster and 10x more cost-effective than Computer Use models. Even better, Agent 3 can now generate other agents and automations to streamline your workflows. What’s New 1. App Testing: Agent tests the apps it builds (using an actual browser) Agent 3 now tests and fixes the app it is building, constantly improving your app behind the scenes. We are launching two different options here, depending on your needs:

    Builder Profile: Jake Weber

    Jake Weber is a multidisciplinary designer, engineer, and writer who has always been drawn to invention as a kind of balance between art and real-world impact. It’s no surprise then that Jake built Printernet, a project that bridges our online lives with tactile experience by “packaging up your bookmarked articles to be read by you, in your hands, in a carefully bound print edition.” Jake’s journey with Replit began in 2021 when he saw a Paul Graham post referencing Replit. Immediately, he was hooked by how easy it was to get up and running quickly. Shortly after, on a long drive back to Austin, Jake reflected on how much reading he was doing online and how the experience of reading off a screen paled compared to picking up and diving into a physical book. What he needed to build was a physical RSS feed. That’s when the idea of Printernet was born. Inspired by an interview with Michael Seibel about launching fast with an MVP, Jake started building Printernet in earnest. Jake first hosted Printernet on Squarespace and started printing the issues himself. Eventually, Product Hunt caught wind of the project, indicating that Jake wasn’t the only one who wanted a physical RSS feed. Today, Jake is building the next version of Printernet on Replit. Jake started integrating Replit into Printernet to build automations to cut down on the time it took to manually compile and format each issue. “I was literally copying and pasting text from websites, one at a time. This process was extremely tedious and probably took 2 to 3 days to fulfill a single order. Once I began developing automations with Replit the time it took to fulfill an order went down dramatically. Now, with my Replit code, the moment an order is placed my Python Repl begins working for me.”
