Two good platforms, built for different scopes
Both can provision, ship and govern. The real question is whether you want a broad suite across many targets and domains, or one platform focused on Kubernetes.
Harness is a broad software delivery platform. Its modules span CI, CD and GitOps, feature flags, infrastructure as code, cloud cost management, chaos engineering, security testing, an internal developer portal and AI-assisted incident response, available as SaaS or self-managed.
That breadth is real, and it deploys to far more than Kubernetes: VMs, serverless, ECS and more. Capabilities are licensed module by module, and getting the most from it usually means configuring several of them together.
- Very broad suite across delivery domains
- Deploys well beyond Kubernetes
- Licensed module by module
- More surface to configure and connect
Atmosly is an internal developer platform built only for Kubernetes. It provisions clusters and cloud resources from a catalog through guardrails, ships code with visual CI/CD and GitOps, gives developers preview environments, and governs it all with RBAC, SSO and one audit trail.
It is one product on one plan, fully managed and agent-based, with a 30-day trial and no credit card. The SquareOps services team can implement and run it for you.
- Built only for Kubernetes, less to configure
- Provisioning, delivery and environments in one product
- Published plans from $399 a month
- SquareOps can implement and run it
Harness is a suite. Atmosly is one Kubernetes platform.
If Kubernetes is where you run, Atmosly gives you provisioning, delivery and environments as one product, configured from what you already run rather than assembled module by module.
From a running workload to a pipeline in under an hour
Point Atmosly at a service already running in your cluster. It reads it, packages it as a blueprint and wires a full pipeline around it, about 47 minutes to first deploy on average.
- Visual editor or YAML, same engine
- Canary, blue-green and rolling, one-click rollback
- Coexists with ArgoCD, Jenkins and GitHub Actions
A catalog of clusters, not modules to write first
IaC tools run the Terraform or OpenTofu modules you write and maintain. Atmosly provisions from a catalog: EKS, GKE or AKS clusters, node groups, version-pinned add-ons and databases, checked against your guardrails.
- Create or import any cluster, public or private
- Cost caps, region and instance allow-lists
- Auto-approve under threshold, one-click revert
Preview environments with prod's policies, by default
Every PR gets its own governed environment with seed data, RBAC, network policies and resource defaults inherited from prod. It is ready in about 2 minutes and expires on merge.
- Policies inherited from prod automatically
- Clone a full stack for a tenant or region
- 200+ vetted Helm charts with your defaults
Harness vs Atmosly, capability by capability
We kept Harness's genuine wins in the table. They're marked so you can see them at a glance.
Harness's wins are real: breadth, deploy targets and mature verification. Atmosly's case is focus: one Kubernetes platform with less to configure. Cloud cost and incident response are SpendZero and Alert6, separate SquareOps products.
Which one is right for your team?
It depends on scope, and on who you want running the platform.
- You deploy well beyond Kubernetes: VMs, serverless, ECS
- Feature flags or chaos engineering are priorities
- You want one vendor across many delivery domains
- ML-based deployment verification is central
- You have the team to configure a broad suite
- Kubernetes is where your workloads run
- You want provisioning, delivery and environments in one product
- You'd rather onboard running services than rebuild pipelines
- You prefer one plan over module-by-module licensing
- You'd like a partner (SquareOps) to implement and run it
If you need a broad suite across many delivery domains and deploy well beyond Kubernetes, Harness is comprehensive. If Kubernetes is your platform and you want provisioning, delivery and environments as one managed product, that's Atmosly.
Connect a cluster freeFrom Harness to Atmosly in an afternoon
No big-bang migration. Connect read-only, onboard one running service, and move Kubernetes delivery over at your own pace.
Rather not do it yourself? The SquareOps services team can run the migration and day-2 operations for you.
Managed Kubernetes servicesWhat teams comparing Harness ask
Not covered? An engineer replies within one business day.
consult@squareops.comHarness is a broad software delivery suite with separate modules for CI, CD, feature flags, IaC, cloud cost, chaos and more, across many deploy targets. Atmosly is one internal developer platform for Kubernetes that provisions, ships and hands out environments in a single product.
Yes. Atmosly works with the clusters and Git repos you already have, so you can keep Harness for non-Kubernetes targets or modules you rely on, such as feature flags, and move Kubernetes delivery over one service at a time.
Not inside Atmosly. Cloud and Kubernetes cost, rightsizing and showback are covered by SpendZero, a separate SquareOps product that connects to the same clusters and accounts.
Atmosly has published plans: Starter at $399 a month, Growth at $1,299 a month and a custom Enterprise tier, with a 30-day trial and no credit card. Harness licenses its capabilities per module, so the total depends on which modules you use.
Not very, and it is incremental. Connect a cluster read-only, onboard one running service into an Atmosly pipeline, then adopt provisioning, environments and guardrails one capability at a time. The SquareOps services team can run the migration for you.
Any conformant Kubernetes cluster: EKS, GKE, AKS or self-managed, public or private, including on-prem and bare-metal. 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. There is no control plane for you to host, patch or upgrade, and SquareOps can run day-2 operations for you. Enterprise customers can self-host the control plane in their own VPC if they need to.
