Teams switch for the larger community (100M+ developers), cleaner UI, and faster performance. GitHub Actions provides CI/CD. Trade-off: lose GitLab's integrated security scanning and self-hosting flexibility.

Atlassian shops switch for native Jira/Confluence integration. Pipelines provides CI/CD. Simpler pricing for small teams. Trade-off: smaller community, fewer integrated DevSecOps features.

Microsoft-centric organizations switch for tight Azure integration. Repos, Pipelines, Boards, and Artifacts in one platform. Similar all-in-one approach. Trade-off: heavier Microsoft ecosystem lock-in.

Teams wanting lightweight self-hosting switch to Gitea. Much faster, minimal resources required, easy to maintain. Open source. Trade-off: no built-in CI/CD (use external), fewer enterprise features.

Teams frustrated with GitLab CI/CD complexity use Jenkins for CI and GitHub for source control. More control over CI configuration. Trade-off: managing multiple tools, integration overhead.
