Why do companies prefer GitLab over GitHub?

Companies prefer GitLab over GitHub mainly due to its integrated DevOps features, self-hosting flexibility, and enhanced security. GitLab offers an all-in-one platform with built-in CI/CD tools, reducing the need for third-party integrations and streamlining workflows. Its self-hosting capabilities provide greater control over data, making it a preferred choice for enterprises with strict security and compliance requirements. 

Additionally, GitLab's customization options and cost-effective pricing make it an attractive solution for organizations seeking a scalable and tailored development environment.
