Two good tools, built for different scopes
Both can build and ship to Kubernetes. The real question is whether you want a DevOps suite with Kubernetes integrations, or a platform built around the cluster.
GitLab CI is a well-integrated pipeline engine configured in .gitlab-ci.yml and run by GitLab Runners, inside a suite that also holds your code, merge requests, issues and security scanning. Review apps, environments and the GitLab agent for Kubernetes, with Flux for GitOps, extend it toward deployment.
It is a broad suite rather than a Kubernetes platform. Provisioning clusters and cloud resources with guardrails, cloning full environments and curating Helm charts are things you assemble from pipelines and other tools, then maintain.
- Kubernetes delivery via agent plus Flux
- Review apps you configure per project
- Provisioning is pipeline code
- No infrastructure guardrails
Atmosly is an internal developer platform for Kubernetes. It provisions clusters and cloud resources through guardrails, ships code with visual CI/CD and GitOps, and gives developers governed environments without a ticket.
It connects to your GitLab repos, so code and reviews stay where they are. It is fully managed and agent-based, and the SquareOps services team can implement and run it for you.
- Governed cluster and cloud provisioning
- GitOps delivery with drift detection
- Preview environments and full-stack cloning
- Fully managed, no self-host upgrades
GitLab runs the SDLC. Atmosly runs the Kubernetes platform.
Keep code, merge requests and CI in GitLab if they work for you. Atmosly adds what sits around the cluster: governed provisioning, self-serve environments and GitOps delivery, with one audit trail.
Provisioning that runs through policy, not a pipeline job
In GitLab, provisioning is OpenTofu or Terraform code in a pipeline you maintain. Atmosly creates the EKS, GKE or AKS cluster, node groups, add-ons and databases from a catalog, through the guardrail flow you design.
- Create or import any cluster, public or private
- Cost caps, region and instance allow-lists on every request
- Auto-approve under threshold, one-click revert
Environments by default, not per-project config
Review apps are something each project wires up in .gitlab-ci.yml. Atmosly gives every PR its own governed environment with policies inherited from prod, and clones a full stack for a new tenant or region in one step.
- Preview environment per PR, auto-expires on merge
- Clone services, config and datastores in one step
- Curated Helm marketplace with pinned versions
GitOps delivery without the agent and Flux setup
In GitLab, GitOps on Kubernetes means installing the agent, configuring Flux and writing deploy jobs. Atmosly turns a running service into a blueprint and pipeline, then deploys it with GitOps sync, drift detection, promotion and one-click rollback.
- Visual editor or YAML, same engine
- Rolling, blue-green and canary deploys
- Deploys the images your GitLab pipelines build
GitLab CI vs Atmosly, capability by capability
We kept GitLab CI's genuine wins in the table. They're marked so you can see them at a glance.
GitLab's strengths are real for the job it's built for: one suite for code, reviews and CI, broad security scanning and flexible hosting. Atmosly's case is the Kubernetes platform around the cluster, built in and managed.
Which one is right for your team?
It depends on scope, and on who you want running the platform.
- Your whole SDLC already lives in GitLab
- You want CI tightly coupled to merge requests
- Broad built-in security scanning matters most
- You need self-managed or Dedicated GitLab
- One vendor for repo, issues and pipelines is the goal
- You want governed provisioning for clusters and cloud resources
- Developers need preview and cloned environments without tickets
- You'd rather not assemble Kubernetes delivery from agent, Flux and YAML
- Guardrails and one audit trail matter across clusters
- You'd like a partner (SquareOps) to implement and run it
If your whole SDLC lives in GitLab and CI tied to merge requests is the priority, GitLab CI fits well. If you want provisioning, environments and Kubernetes delivery run as one platform, that's Atmosly.
Connect a cluster freeFrom GitLab CI to Atmosly in an afternoon
No big-bang migration. Keep GitLab for code and reviews, connect a cluster read-only, and adopt Atmosly one capability at a time.
Rather not do it yourself? The SquareOps services team can run the migration and day-2 operations for you.
Managed Kubernetes servicesWhat teams comparing GitLab CI ask
Not covered? An engineer replies within one business day.
consult@squareops.comGitLab CI is the pipeline engine of the GitLab DevOps suite, tightly tied to your repos and merge requests. Atmosly is a managed internal developer platform for Kubernetes that adds governed provisioning, GitOps delivery, and preview and cloned environments.
Yes. Code, merge requests and issues stay in GitLab. Atmosly can take source webhooks from GitLab and run the pipeline itself, or deploy the images your GitLab CI pipelines already build.
Review apps are something you configure per project in .gitlab-ci.yml. Atmosly gives every PR a governed environment by default, with RBAC, network policies and resource defaults inherited from prod, and it can also clone a full stack for a tenant or region.
Partly. Atmosly's CI/CD pipelines include scan steps such as Trivy image scanning, secret detection and custom scripts, so the checks that gate a build live in the pipeline. GitLab's built-in scanning is broader, so keep it if it serves you. Vulnerability scanning and compliance posture for clusters are Verity, a separate SquareOps product.
Not very, and it is incremental. Keep GitLab running, connect a cluster read-only, move one service's deployment to Atmosly, then adopt environments and guardrails at your own pace. The SquareOps services team can run the migration for you.
Any conformant Kubernetes cluster: EKS, GKE, AKS or self-managed, including on-prem and bare-metal, public or private. You import the cluster you already run, read-only, in minutes.
No. It runs on your own clusters on standard Kubernetes, Helm and Git, so what you build stays portable.
It is fully managed and agent-based, read-only by default, with no control plane for you to host or upgrade. Enterprise customers can self-host the control plane in their own VPC, and SquareOps can run day-2 operations for you.
