GitHub Copilot vs Replit AI

TL;DR: GitHub Copilot is a code completion tool that lives in your existing editor and helps you write code faster line-by-line, while Replit AI is a complete development environment that can build entire full-stack applications from prompts and includes hosting, databases, and deployment infrastructure. Choose Copilot if you want AI assistance within your current workflow, or Replit if you need an all-in-one platform that handles both development and deployment. Replit offers a more generous free tier and targets beginners alongside professionals, whereas Copilot assumes you already have a development setup.
