Most common switch. Teams migrate for better UI, larger community (100M+ developers), superior marketplace, and GitHub Copilot AI assistance. Trade-off: GitHub costs $4/user vs $3 for Bitbucket Standard, less Jira integration depth.

Teams switch for all-in-one DevSecOps with superior CI/CD. GitLab's built-in CI is unlimited minutes on self-hosted. Trade-off: GitLab Cloud can be slow, Premium is $29/user vs Bitbucket's $6, steeper learning curve.

Microsoft shops switch for tighter Azure/VS integration and enterprise-grade project management. Free for small teams (up to 5 users). Trade-off: Heavy Microsoft lock-in, overkill for simple Git workflows.

Teams wanting lightweight self-hosted Git switch to Gitea. It's open source, fast, and runs on minimal resources. Trade-off: No built-in CI/CD, smaller ecosystem, DIY maintenance.

AWS-heavy teams migrate for native AWS integration and IAM-based access control. Trade-off: Basic Git hosting only, minimal UI features, AWS lock-in.
