⚔️ GitLab CI vs Jenkins: Which One Should You Choose?

Both GitLab CI and Jenkins are popular tools for automating builds, tests, and deployments.
But they follow different philosophies and suit different types of teams.

• Easy integration with Kubernetes
• Modern UI and permissions system

🚫 Cons:

• Tied to GitLab ecosystem
• Less flexible than Jenkins for custom environments
