Keep governed IaC. Add the app loop.
Spacelift is a strong IaC orchestration platform for Terraform, OpenTofu, and friends. But infrastructure is only half the story — application delivery and runtime operations are separate. Atmosly brings governed provisioning and the full app loop together.
- ✓ Governed provisioning included
- ✓ Read-only to start
- ✓ No self-host upgrades
Two good tools, built for different scopes
Both work with Kubernetes. The real question isn't whose feature is better — it's how much of the lifecycle you want one product to own.
Spacelift is a strong infrastructure-as-code orchestration platform — runs, policies, and state management for Terraform, OpenTofu, Pulumi, and CloudFormation, with serious governance.
It is infrastructure-centric. Application CI/CD, Kubernetes incident response, live compliance posture, and workload cost sit outside its scope and are handled by other tools.
- Infra-focused — app delivery is separate
- No AI SRE or Kubernetes incident response
- No continuous workload compliance posture
- No native workload cost intelligence
Atmosly is one unified Kubernetes platform. Code flows through visual CI/CD and GitOps; the AI SRE agent watches what's running and proposes ranked fixes; the security engine scans posture continuously; and cost intelligence shows where the money goes.
It's fully managed and agent-based — no self-hosted upgrades to chase. And the SquareOps services team can implement and run it for you.
- AI SRE: root cause + ranked fix PRs
- Continuous CIS / PCI / SOC 2 posture
- Built-in cost intelligence & FinOps
- Fully managed — zero upgrade toil
Spacelift provisions infra. Atmosly provisions and runs apps.
Atmosly includes governed provisioning and guardrails, then adds the application delivery and runtime loop Spacelift leaves to other tools.
An AI SRE for what's running
When a pod OOMKills or a service crash-loops, Atmosly infers the actual root cause and opens the PR that fixes it — with a full audit trail. Read-only by default, every action reversible.
- Root cause in under a minute, fix proposed
- Read-only by default — every action reversible
- No runbooks to write, no rotation to staff
Continuous posture, not a build-time scan
Always-on scanning against CIS, PCI DSS, SOC 2, and NSA hardening, with audit-ready evidence on demand — watching the live cluster for drift, not just images at build time.
- CIS · PCI · SOC 2 · NSA frameworks built in
- Drift caught on the running cluster
- Audit-ready evidence exported on demand
Cost you can see, leaks closed automatically
Per-namespace and per-workload cost, right-sizing from real usage, and waste detection built in — reconciled to your bill, with guardrails that scale non-prod down on a schedule.
- Cost by service & namespace, reconciled to the bill
- Right-sizing from real usage, not guesswork
- Guardrails scale non-prod down on a schedule
Spacelift vs Atmosly, capability by capability
The capabilities below are the ones Atmosly brings to one platform. We've kept Spacelift's genuine wins in the table too.
Spacelift's strengths are real for the job it's built for. Atmosly's case is scope and managed operations across the whole loop.
Which one is right for your team?
Here's how to decide based on scope and who you want running the platform.
- IaC orchestration is your primary need
- You manage large Terraform/OpenTofu estates
- Policy-as-code on infra runs is essential
- You handle app delivery in separate tools
- Your focus is infrastructure, not workloads
- You want delivery plus AI SRE, security & cost in one loop
- You'd rather not spend engineer-weeks self-hosting a platform
- Continuous compliance posture matters, not just scans
- You want auto root-cause and fix PRs for incidents
- You'd like a partner (SquareOps) to implement and run it
The bottom line: If managing large Terraform/OpenTofu estates with policy-as-code is the core need, Spacelift is excellent. If you want governed provisioning plus the application delivery and runtime loop on one platform, that's Atmosly.
From Spacelift to Atmosly in an afternoon
No big-bang migration. You connect read-only, see value first, and adopt the rest of the loop at your own pace — keeping the GitOps and Helm you already run.
Connect read-only
Import your existing EKS, GKE, or AKS cluster — public or private — in minutes. Nothing changes; Atmosly just starts observing.
Bring what you run
Point Atmosly at your existing clusters, Git repos, and Helm releases. It's standard Kubernetes underneath — nothing to recreate.
Turn on the loop
Switch on visual CI/CD, the AI SRE agent, continuous security, and cost intelligence as you're ready — one capability at a time.
Hand off the toil
Atmosly is fully managed — no self-host upgrades to chase. SquareOps can run day-2 operations for you if you'd like.
