GitHub Copilot

What is GitHub Copilot?

GitHub Copilot is the most widely adopted AI coding assistant, used by over 1.8 million developers and 77,000 organizations worldwide. Built on OpenAI Codex models and deeply integrated into the GitHub ecosystem, it provides real-time code completions, explanations, test generation, and chat directly within your IDE. Copilot supports Visual Studio Code, JetBrains IDEs, Neovim, and Visual Studio, making it accessible across virtually every development environment.

What sets Copilot apart from competitors like Cursor or Windsurf is its GitHub integration. It understands your repositories, pull requests, issues, and Actions workflows natively. Copilot Chat can reference your entire codebase, explain unfamiliar code, suggest refactoring approaches, and generate unit tests based on existing functions. The free tier, introduced in late 2024, provides 2,000 code completions and 50 chat messages per month, making it the easiest way for individual developers to try AI-assisted coding at zero cost.

For teams and enterprises, Copilot offers organization-wide policy controls, audit logs, IP indemnity, and the ability to exclude specific files or repositories from AI processing. The Business ($19/user/mo) and Enterprise ($39/user/mo) tiers add knowledge base indexing, fine-tuned models for your codebase, and admin-level controls for managing AI usage across large engineering organizations. In 2026, Copilot remains the safe default choice for developers who want AI assistance without leaving their existing editor or adopting a new IDE.
