Architecture comparison

Stella Ops vs GitLab CI/CD

GitLab CI/CD is an integrated DevOps platform for build and delivery pipelines.
Stella adds reachability-aware release decisioning and signed promotion evidence independent of CI vendor.

Decision criteria

How this comparison is evaluated

Each vendor page is scored against the same five technical dimensions for consistent decision support.

Deployment model: Target coverage, self-hosting posture, and runtime assumptions.
Evidence model: How decisions are justified, signed, and exported for review.
Replayability: Ability to re-run historical decisions with identical inputs.
Offline capability: Behavior in disconnected or sovereign environments.
Policy model: Gate expressiveness, explainability, and workflow integration.

GitLab CI/CD

⬢ Integrated DevOps platform
⬢ Cloud or self-managed options
⬢ Built-in container registry
⬢ Basic security scanning (Ultimate tier)
⬢ Pipeline-based deployment

Stella Ops Suite

⬢ Release orchestration control plane
⬢ 100% self-hosted, air-gap ready
⬢ Works with any registry
⬢ Reachability?Analysis that proves whether vulnerable code is actually called by your application — filtering out false positives from scanner noise-aware scanning (all tiers)
⬢ Evidence-gated promotions

Dimension-by-dimension comparison

Decision dimension	GitLab	Stella Ops
Build automation	Yes	Integrates with CI
Deployment pipelines	Yes	Yes
`Environment?A logical deployment target (e.g. dev, staging, prod) that tracks its own release history, promotion rules, and policy gates` management	Yes	Yes (promotion graphs)
Container scanning	Ultimate tier only	All tiers
`Reachability?Analysis that proves whether vulnerable code is actually called by your application — filtering out false positives from scanner noise` analysis	No	Yes (hybrid 3-layer)
`SBOM?Software Bill of Materials - a complete list of all packages and dependencies in your software` generation	Ultimate tier	All tiers
Decision Capsules	No	Yes
Deterministic replay	No	Yes
Air-gap deployment	Partial (self-managed)	Full (Offline Kit)
Non-Kubernetes focus	Secondary	Primary

The Security Gap

GitLab's security scanning (Ultimate tier) tells you a CVE exists. Stella Ops tells you if it's actually exploitable in your code.

Terminal

$ stella scan myapp:latest
✓ 487 CVEs found in dependencies
✓ 475 NOT REACHABLE (filtered out)
! 12 REACHABLE (evaluated against policy)

Policy verdict: PASS
Evidence exported: decision-capsule-2025-01-15.json

Focus on 12 actual risks instead of triaging 487 theoretical vulnerabilities.

Operational fit and deployment model

GitLab deploys via pipeline scripts. Stella provides structured release orchestration for non-Kubernetes targets:

Deployment Targets

→ Docker Compose deployments
→ Docker Swarm clusters
→ AWS ECS / Fargate
→ HashiCorp Nomad
→ Scripted deployments (.NET 10)

Infrastructure Integration

→ SSH/WinRM remote deployment
→ HashiCorp Vault for secrets
→ HashiCorp Consul for service registry
→ Environment?A logical deployment target (e.g. dev, staging, prod) that tracks its own release history, promotion rules, and policy gates promotions (Dev→Stage→Prod)
→ Approval workflows

GitLab security features require Ultimate tier (~$99/user/month)

Stella Ops includes all security features at every tier — starting free

Fit guidance by deployment and evidence needs

GitLab-only fit

⬢ Kubernetes is your deployment target
⬢ GitLab Ultimate tier is already in use
⬢ Basic scanning without reachability is OK
⬢ Audit evidence isn't required

Add Stella fit

⬢ You need reachability analysis
⬢ Non-Kubernetes is your primary target
⬢ Auditors need Decision Capsules
⬢ Air-gap deployment is required
⬢ You want security at all tiers
