GitHub

GitHub hosts source code for individual developers and whole organisations, and gives them tools to plan, review, test and release it. It is also where a very large open source community keeps its projects, and it now brings AI agents into the same workflow.

What GitHub offers

• GitHub Copilot — AI help for writing, fixing and refactoring code, plus agents that can take an issue through to a change.
• Actions — CI/CD automation for building, testing and deploying.
• Codespaces — cloud development environments that open in seconds.
• Issues, projects and code review — planning from roadmaps to daily tasks, and reviewing changes before merge.
• Advanced Security — vulnerability fixing with Copilot Autofix, dependency updates and secret protection.
• Marketplace and MCP Registry — apps, actions and integrations that extend the toolchain.

Who it works with

GitHub has plans for enterprises, small teams, startups and non-profits, with industry pages for healthcare, financial services, manufacturing and government. GitHub Sponsors lets people fund open source maintainers.
