Replit Agent 3 marks a turning point in the way we approach software creation. Instead of acting like a traditional tool, it behaves more like a collaborator — capable of running autonomously, testing its own work, and even building agents and automations that extend far beyond apps.
Context
Replit began the journey to Agent 3 with a simple idea: making it possible for anyone to turn an idea into software. Earlier versions of Replit’s agent laid the groundwork, but Agent 3 takes a leap forward. It isn’t just faster — it’s smarter, more reliable, and closer to how we expect a skilled partner to work.
Smarter Autonomy
One of the biggest advancements is autonomy. Agent 3 can run on its own for up to 200 minutes, breaking down goals, building step by step, and keeping progress moving while you focus on the bigger picture. This shift reduces the need for constant input and unlocks new levels of productivity.
Self-Testing
For the first time, the agent can test and fix its own work. Using a live browser environment, Agent 3 checks the apps it builds, identifies issues, and resolves them before presenting results. This self-correction cycle moves it from being a simple executor to a problem-solving collaborator.
Beyond Apps: Agents & Automations
Agent 3 expands the idea of what can be built. It’s not limited to apps — now you can create agents and automations that integrate with platforms like Slack, Telegram, or email. From daily reminders to data-fetching bots, it allows anyone to create small but powerful tools that streamline everyday workflows.
A New Way of Building
Agent 3 shows what’s possible when AI is designed to feel human-centered. By handling the repetitive and technical work, it allows creators to stay focused on vision and ideas. This release puts Replit in a category of its own, setting a new standard for what it means to truly collaborate with AI.
