GitHub Copilot

GitHub Copilot integrates directly into VS Code, Visual Studio, JetBrains IDEs, and Neovim, offering inline code completions, a chat interface for asking questions about your code, and an agent mode that can carry out multi-step tasks like implementing a feature or fixing a failing test across several files. Being built by GitHub and Microsoft gives it strong enterprise positioning — security and policy controls for organizations, and tight integration with GitHub's pull request and Actions workflows. A free tier launched in recent years gives individuals a monthly allowance of completions and chat messages at no cost; paid plans starting around $10/mo (Copilot Pro) remove most limits and unlock access to more capable underlying models. Historically, Copilot's project-wide context was weaker than dedicated AI editors like Cursor or Windsurf, though agent mode has narrowed that gap; very large or unusual codebases can still get better mileage from those alternatives.
