GitHub

GitHub is the world's largest code hosting and collaboration platform, providing Git-based version control, CI/CD via GitHub Actions, and project management tools used by over 100 million developers. Acquired by Microsoft in 2018, it has expanded beyond code hosting into AI-assisted development with GitHub Copilot, an LLM-powered coding assistant. GitHub also serves as critical infrastructure for open-source software supply chains, making it a frequent target of security research and a key platform in the modern software development ecosystem.

GitHub Copilot 9

GitHub Copilot is Microsoft/GitHub's AI-powered coding assistant that integrates directly into IDEs to provide inline code completions, a conversational chat interface, CLI assistance, and autonomous background agent capabilities. Originally launched as a tab-complete tool built on OpenAI Codex, it has evolved into a multi-model agentic platform supporting automated code edits, pull request reviews, and per-session git worktree isolation for background tasks. It is widely regarded as the category-defining AI coding assistant and a primary driver of mainstream developer adoption of LLM-assisted programming.
