GitHub Copilot

GitHub Copilot is the most widely adopted AI coding assistant, integrated directly into popular development environments including VS Code, JetBrains IDEs, Neovim, and the GitHub web editor. Developed by GitHub in collaboration with OpenAI, Copilot provides real-time code completions, an AI chat assistant for code-related questions, and a CLI tool for terminal commands. It supports every major programming language and framework, with particularly strong performance in Python, JavaScript, TypeScript, Go, and Ruby. Copilot's code completions are context-aware, analyzing your open files, imports, and coding patterns to suggest entire functions, classes, and boilerplate blocks. The Chat feature allows developers to ask questions about their codebase, generate unit tests, explain unfamiliar code, and get debugging assistance without leaving their editor. The free tier offers 2,000 code completions and 50 chat messages per month, while the $10/month Pro plan provides unlimited access. Copilot Business at $19/month adds organizational management, IP indemnity, and policy controls for enterprise teams. With over 1.8 million paying subscribers and integration into the GitHub platform where most open-source development happens, Copilot benefits from an unmatched training foundation and seamless version control integration.
