Two good tools, built for different scopes
Both ship to Kubernetes with visual pipelines and GitOps. The real question is who runs the platform, and how much of provisioning and self-service you want built in.
Devtron is an open-source (Apache 2.0) Kubernetes platform: visual CI/CD, GitOps built on Argo CD, Helm app management, a multi-cluster resource browser, RBAC and image scanning. Recent releases add observability, cost visibility and an agentic SRE layer.
The open-source edition is yours to host, secure and upgrade, with more features in a paid enterprise edition. Cluster provisioning runs through pipeline plugins, and per-PR environments are something you configure rather than a built-in flow.
- Self-hosted: you run the upgrades
- Provisioning via pipeline plugins
- Preview environments you set up
- Enterprise features in a paid edition
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 is fully managed and agent-based, with no platform to host, patch or upgrade. The SquareOps services team can implement and run it for you.
- Governed provisioning for clusters and resources
- Visual CI/CD and native GitOps
- Preview environments and cloning
- Fully managed, zero upgrade toil
Same delivery model. No platform to run.
Atmosly keeps the visual pipelines and GitOps Devtron users rely on, and adds the provisioning, environments and guardrails around them, without a self-hosted platform to maintain.
Clusters and resources from a catalog, not a pipeline step
Atmosly creates EKS, GKE or AKS clusters, or imports any conformant one, then provisions node groups, add-ons, databases, caches and queues next to it. Every request runs 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
Developers get environments without filing tickets
Every PR gets its own governed environment with policies inherited from prod. Clone a full stack for a new tenant or region, or install a vetted Helm chart with your defaults pre-applied.
- Preview environment per PR, auto-expires on merge
- Clone services, config and datastores in one step
- Curated Helm marketplace with pinned versions
Guardrails on every request, one audit trail
Provisioning, deploys and terminal sessions all run through the same policy and land in one audit trail, so the platform team can say yes to self-service without reviewing every change by hand.
- Fine-grained RBAC with SAML SSO
- Audited web terminal for scoped kubectl
- Read-only by default, everything reversible
Devtron vs Atmosly, capability by capability
We kept Devtron's genuine wins in the table. They're marked so you can see them at a glance.
Devtron's strengths are real: a free, open-source platform with a large community and a strong multi-cluster view. Atmosly's case is governed provisioning and environments, without a platform to host.
Which one is right for your team?
It depends on scope, and on who you want running the platform.
- You want a free, open-source Kubernetes platform
- Self-hosting and keeping everything in-house matters
- You have engineers to own upgrades and break-fix
- Observability and cost views in the same tool appeal
- You like building on Argo CD directly
- You'd rather not host and upgrade a platform
- Provisioning clusters and resources should be governed
- Developers need preview environments without tickets
- Guardrails and one audit trail matter across clusters
- You'd like a partner (SquareOps) to implement and run it
If you want a free, open-source Kubernetes platform and have engineers to run it, Devtron is a genuinely good choice. If you want the same delivery model plus governed provisioning and environments, fully managed, that's Atmosly.
Connect a cluster freeFrom Devtron to Atmosly in an afternoon
No big-bang migration. Connect read-only, see value first, and move apps over at your own pace, keeping the GitOps, Helm and clusters you already run.
Rather not do it yourself? The SquareOps services team can run the migration and day-2 operations for you.
Managed Kubernetes servicesWhat teams comparing Devtron ask
Not covered? An engineer replies within one business day.
consult@squareops.comBoth give you visual CI/CD and GitOps for Kubernetes. Devtron is open source and usually self-hosted, while Atmosly is fully managed and adds governed cluster and resource provisioning, per-PR preview environments and guardrails on every request.
No. Atmosly is GitOps-native with drift detection, so deployments stay declarative and portable on standard Kubernetes, Helm and Git. It also coexists with Argo CD if you want to keep it.
Recent Devtron releases bundle observability, cost visibility and an agentic SRE layer into one platform. Atmosly stays focused on provisioning, delivery and self-service. SquareOps covers incident detection and automated remediation with Alert6 and cloud cost with SpendZero, as separate products.
Self-hosting is not free: someone patches, upgrades and fixes the platform, and builds the provisioning and environment flows on top. Atmosly is managed and ships those built in. If you have the engineers and want to stay open source, Devtron is a fine choice.
Not very, and it is incremental. Import the clusters you already run read-only, turn one running service into a blueprint and pipeline, then move the rest one app 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, and read-only by default, so there is 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.
