GitHub

GitHub is the platform where most of the world's code is hosted, reviewed, and shipped: repositories, pull requests, Issues, and GitHub Actions for CI/CD, plus Codespaces for a cloud dev environment you can open from any browser. It's also fast becoming the place where AI agents do real work, not just where humans write code. The Copilot coding agent takes a GitHub Issue, works in an isolated sandbox, and opens a pull request on its own; GitHub Actions can run AI steps as part of a build; and GitHub's official MCP server lets any MCP-compatible agent (Claude included) read and write repos, Issues, and PRs directly. The catch is the "proprietary incumbent" trade-off: GitHub is free to start and has enormous network effects (open-source projects, collaborators, integrations all assume you're there), but it's owned by Microsoft, closed-source, and there's no self-hosting your way out short of the expensive Enterprise Server tier.
