Two good tools, built for different scopes
Both work with Kubernetes. The real question is whether you want a portal that triggers your tools, or a platform that does the work.
Port is a low-code internal developer portal: a flexible software catalog built on your own data model, scorecards for standards, and self-service actions with approvals and an audit log. It is SaaS, with a free tier to start.
It is an orchestration and presentation layer. When a developer runs an action, Port calls a backend you own, such as a CI workflow, a Terraform run or a webhook. Provisioning and deploying still happen in those systems, which you keep building and maintaining.
- Actions call backends you maintain
- Doesn't provision or deploy itself
- Environments need your own automation
- Best as a layer over existing tools
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.
The self-service is the execution: there is no backend to write behind each button. It is fully managed and agent-based, and 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
Port triggers the work. Atmosly does the work.
Instead of a portal that calls pipelines and scripts you maintain, Atmosly provisions infrastructure, deploys code and creates environments itself, with guardrails on every request.
Provisioning that runs, not an action that hands off
A Port action calls a Terraform run or workflow you wrote and maintain. Atmosly creates the EKS, GKE or AKS cluster, node groups, add-ons and databases from its own 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
One pipeline from commit to production
No pipeline to build behind a button. Point Atmosly at a service that is already running and it packages it as a blueprint with a full pipeline: build, test, deploy, verify and promote, with GitOps sync and one-click rollback.
- Visual editor or YAML, same engine
- Post-deploy verification and approval gates
- Coexists with ArgoCD, Jenkins and GitHub Actions
Environments are a feature, not an action you script
In a portal, a new environment is an action wired to automation you maintain. In Atmosly, every PR gets its own governed environment with policies inherited from prod, and cloning a full stack is one step.
- Preview environment per PR, auto-expires on merge
- Clone services, config and datastores in one step
- Curated Helm marketplace with pinned versions
Port vs Atmosly, capability by capability
We kept Port's genuine wins in the table. They're marked so you can see them at a glance.
Port's strengths are real for the job it's built for: a flexible catalog, scorecards and a portal over many tools. Atmosly's case is that the actions run on the platform itself, with no backends for you to build.
Which one is right for your team?
It depends on scope, and on who you want running the platform.
- You want a flexible catalog over many existing tools
- Scorecards and standards tracking are the priority
- Your delivery and IaC backends are already solid
- A low-code portal layer fits your org
- A free tier to start with matters
- You want actions that run, not scripts you maintain
- Provisioning and delivery should live on one platform
- Developers need environments without filing tickets
- Guardrails and one audit trail matter across clusters
- You'd like a partner (SquareOps) to implement and run it
If you want a flexible catalog and scorecards layered over the tools you already run, Port is a strong portal. If you want the platform those actions run on, with provisioning, delivery and environments in one place, that's Atmosly.
Connect a cluster freeFrom Port to Atmosly in an afternoon
No big-bang migration, and you can keep Port as your catalog if you like. Connect read-only, see value first, and adopt the rest at your own pace, keeping the GitOps and Helm you already run.
Rather not do it yourself? The SquareOps services team can run the migration and day-2 operations for you.

consult@squareops.comPort is a developer portal whose self-service actions trigger backends you build, such as CI workflows, Terraform runs or webhooks. Atmosly is the platform that does the work itself: it provisions clusters and resources, deploys code and creates environments on Kubernetes.
Yes. Some teams keep Port as their catalog and front door and use Atmosly for provisioning, delivery and environments on Kubernetes. Atmosly runs on standard Kubernetes, Helm and Git, so it sits next to the tools you already use.
Yes. Developers request resources from a catalog, get a preview environment per pull request, clone full stacks and install vetted Helm charts, all through guardrails, without anyone writing a backend for each action.
Not in the same way. Atmosly enforces standards up front with guardrail policies, RBAC and one audit trail, and its service catalog shows each service's owner, pipeline, environments and deploy status. If maturity scorecards across many tools are the main goal, Port is stronger there.
Not very, and it is incremental. Connect a cluster read-only, ship one workload through an Atmosly pipeline, then move the automation behind your portal actions over 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, 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.
