GitHub Actions vs GitLab CI vs CircleCI — UK CI/CD (2026)
GitHub Actions is ClickMasters' default for all UK projects on GitHub — tightest GitHub integration, largest marketplace of actions, and AWS OIDC (no long-lived credentials — strongest Cyber Essentials A3 access control). GitLab CI is right when the team uses GitLab (built-in CI/CD is GitLab's core strength — no separate tool needed). CircleCI is legacy for most new UK projects — GitHub Actions has matched or exceeded CircleCI for typical UK use cases. CI/CD platform choice affects UK Cyber Essentials A2 (14-day patching evidence), FCA PS21/3 change management audit trail, and AWS OIDC security posture.
| Factor | GitHub Actions | GitLab CI | CircleCI |
|---|---|---|---|
| AWS OIDC (no long-lived credentials) | ✅ Native — GitHub OIDC → AWS IAM role | ✅ GitLab OIDC — available | CircleCI OIDC — available |
| Cyber Essentials patching evidence | ✅ Actions run history — Dependabot PR merge = patch audit trail | Merge request pipeline history | CircleCI pipeline history |
| FCA PS21/3 change management | ✅ Required status checks + branch protection = change gate | Merge request approvals — equivalent | Required context checks — available |
| NHS DTAC Domain 3 security scans | ✅ Marketplace: Semgrep, Trivy, OWASP ZAP actions pre-built | GitLab SAST/DAST built-in — good | CircleCI orbs for Snyk, Trivy |
| GitHub integration | ✅ Native — same platform | Requires webhook/mirror | GitHub connector available |
| Self-hosted runners (NHS data residency) | ✅ GitHub Actions self-hosted runners — eu-west-2 | ✅ GitLab Runner self-hosted — eu-west-2 | CircleCI self-hosted runners — available |
| Cost at medium UK team (10 devs) | ✅ GitHub Teams + Actions included | GitLab Premium (~£15/user/month) | CircleCI (~£400+/month for medium usage) |
| ClickMasters default | ✅ All GitHub-based UK projects | All GitLab-based UK projects | Legacy only — no new projects |
