GitLab and GitHub are web-based Git repository managers that provide source code management (SCM), as well as added features like bug tracking, feature requests, task management, and wikis for every project.

GitLab is an open-source solution that includes both a free and paid version with more advanced features. It also provides a complete DevOps platform, including CI/CD pipelines, and integrated tools for monitoring, security, and management.

GitHub, on the other hand, is primarily a web-based platform that offers both free and paid plans. It's widely used by developers, open-source projects, and businesses. GitHub also offers a range of tools for collaborative work and project management, including pull requests and issue tracking.

Both GitLab and GitHub provide a web interface for managing Git repositories and offer robust collaboration features that make it easy for developers to work together on projects. The choice between the two largely depends on the specific needs and requirements of an organization or individual.
