GitHub vs GitLab vs Bitbucket

GitHub, GitLab, and Bitbucket are the three leading Git hosting platforms, each with distinct philosophies. GitHub dominates open source and developer community with the largest ecosystem. GitLab offers a complete DevOps platform in a single application with built-in CI/CD, security scanning, and project management. Bitbucket integrates tightly with the Atlassian ecosystem of Jira and Confluence, making it popular among teams already using those tools.
