| **Pipeline Definition** | `.gitlab-ci.yml` | `.github/workflows/*.yml` |
| **Stages** | 5 explicit stages | Implicit via dependencies |
| **Jobs** | 11 jobs | 10+ jobs across workflows |
| **Artifacts** | Built-in support | `upload-artifact` action |
| **Container Registry** | Integrated | GitHub Container Registry |
| **Manual Jobs** | `when: manual` | `workflow_dispatch` |
| **Environments** | Native support | Environment protection rules |
| **Variables** | Project/Group/Instance | Repository secrets |
| **Runner Management** | Self-hosted + shared | Self-hosted + GitHub-hosted |

**Advantage**: Both platforms now supported! Choose based on preference or use both.
