Replit AI transforms how you build software with Agent, our AI-powered development assistant. Agent allows you to build entire applications in minutes, without knowing how to code.
New with Agent 3 - Extended autonomous builds with minimal supervision, App Testing for self-validation, two ways to start an app (design-first vs. full app first), and Agents & Automations for building your own autonomous systems.

​
What you can build

With Agent, you can:
  • Transform ideas into apps: Describe your vision in plain language and watch Agent build a complete application
  • Accelerate development: Get instant code explanations, intelligent autocomplete, and contextual help
  • Debug efficiently: Identify and fix issues with AI-powered analysis and suggestions
  • Learn as you build: Receive detailed explanations and best practice recommendations
