GitHub Copilot is the world’s most adopted AI-powered developer platform, acting as an AI pair programmer that helps developers write code faster and with less context-switching. Unlike tools focused purely on generating snippets, Copilot deeply integrates into the developer’s workflow (IDE, terminal, and GitHub.com) to function as an autonomous agent. It not only autocompletes lines but also handles complex, multi-file tasks, explains legacy code, and automatically fixes security vulnerabilities .
Its standout function is the Copilot Coding Agent and Agent Mode. Instead of just suggesting code, you can delegate entire tasks to it—like “refactor this service for better error handling” or “add unit tests to the utils folder”—and the agent will autonomously plan, write, and implement the code across your codebase. It creates a draft pull request with all the changes, allowing you to review them before merging . This is supported by Copilot Extensions, which allow it to integrate with external services like Datadog or Sentry directly from your IDE . GitHub Copilot is available as extensions for VS Code, Visual Studio, and JetBrains IDEs, as well as a web experience on GitHub.com
