Why Teams Are Looking Beyond Spacelift
Spacelift built its name on multi-IaC orchestration — Terraform, OpenTofu, Pulumi, CloudFormation, Ansible, and Kubernetes all under one roof. For platform teams juggling multiple frameworks, that breadth was the selling point. But its concurrency-based pricing creates real problems at scale. Every parallel run costs money, and hitting the tier ceiling means either queuing runs or paying for an upgrade. Governance features like custom policies and advanced RBAC also sit behind higher tiers, which frustrates teams that need compliance tooling without enterprise contracts.
The IaC space shifted considerably since 2024. IBM acquired HashiCorp and pushed HCP Terraform toward enterprise-first pricing. OpenTofu matured past v1.10 with OCI registry support and native S3 state locking. Several competitors sharpened their positioning in response — some going deeper on Terraform/OpenTofu specifically, others expanding multi-framework coverage.
If you’re evaluating whether to stay on Spacelift or switch, here’s what each alternative actually offers in mid-2026.
env0: Multi-Framework IaC With Built-In Cost Controls
env0 supports Terraform, OpenTofu, Pulumi, CloudFormation, Terragrunt, Ansible, Kubernetes, and custom workflows through its “Custom Flows” system. If your organization runs multiple IaC frameworks simultaneously, env0 handles that without asking you to consolidate.
Strengths
Cost estimation and budget enforcement. Infracost-powered cost projections run on every plan. You can set hard budget caps per environment — the system blocks applies that would exceed the threshold. Published data claims teams save roughly 45% on IaC-related cloud costs with these controls active.
Self-service environments. Developers spin up full infrastructure stacks from a catalog without writing Terraform. TTL-based auto-destruction keeps temporary environments from accumulating cost overnight.
Unlimited concurrency on all plans. Where Spacelift gates concurrency behind tiers, env0 runs as many parallel deployments as needed regardless of plan level. For teams with high PR volumes or monorepo setups, this removes the queuing bottleneck entirely.
Drift detection and auto-remediation. Scheduled scans compare deployed state against your code. When drift appears, env0 can alert or automatically trigger a corrective run — configurable per workspace.
Limitations
Some governance capabilities (custom approval workflows, granular RBAC) sit behind higher tiers. The UI is functional but less polished than Spacelift’s for visualizing stack dependencies. Documentation for Custom Flows can be sparse for less common framework combinations.
Pricing
Tier-based. Free plan covers 5 environments. Paid plans start around $10/user/month for Team, scaling up for Pro and Enterprise. No per-resource or per-run charges — concurrency is unlimited across all tiers.
Best For
Organizations running multiple IaC frameworks that need cost governance baked into the deployment pipeline. Strong fit for teams migrating from Spacelift who want similar breadth without concurrency constraints.
HCP Terraform (Terraform Cloud): The HashiCorp-Native Path
After IBM’s acquisition closed in early 2025, Terraform Cloud became “HCP Terraform.” The legacy free tier hit end-of-life on March 31, 2026, with remaining organizations migrated to a pay-as-you-go model capped at 500 managed resources.
Current Pricing (June 2026)
Paid tiers charge per managed resource per month:
- Essentials: $0.10/resource/month
- Standard: $0.47/resource/month
- Premium: $0.99/resource/month
A “managed resource” is any infrastructure object tracked in Terraform state — an EC2 instance, an S3 bucket, a security group rule. For a team managing 2,000 resources on Standard, that’s roughly $940/month before enterprise add-ons.
Strengths
Native Terraform integration. New Terraform features land here first, with no abstraction layer between you and the tool.
Sentinel and OPA policy enforcement. Write governance rules that block non-compliant infrastructure before it deploys. Sentinel is proprietary to HashiCorp; OPA support added later for teams preferring open standards.
Private module registry. Host internal modules and providers. Share vetted infrastructure patterns across teams without publishing publicly.
Encrypted, versioned state with locking. The foundational reason most teams originally adopted Terraform Cloud.
Limitations
Per-resource pricing punishes infrastructure growth — stable resources that rarely change still cost monthly. Concurrency is limited (1 on free, typically 3-5 on paid tiers). Only supports Terraform and OpenTofu. No Pulumi, CloudFormation, or Ansible support means you need separate tooling for multi-framework environments.
Best For
Teams exclusively using Terraform with under 5,000 resources, or organizations already invested in the HashiCorp/IBM product family (Vault, Consul, Nomad).
Scalr: Terraform-Focused With Per-Run Pricing
Scalr occupies a specific niche: a managed Terraform/OpenTofu platform that mirrors HCP Terraform’s workflow but replaces the pricing model and ships governance features that HCP Terraform locks behind enterprise tiers. Scalr holds a founding seat on the OpenTofu steering committee, which signals long-term commitment to the open-source fork.
Strengths
Per-run pricing. Charges per qualifying plan/apply execution rather than per resource under management. Drift detection runs are free. Stable infrastructure that rarely changes costs almost nothing, while active development phases cost proportionally more.
Ungated governance. OPA policy enforcement, custom approval workflows, hierarchical RBAC, and audit logging ship on all paid plans. No tier upgrades needed for compliance.
Hierarchical environment model. Account → Environment → Workspace. Policies and variables cascade downward — set a tagging policy at account level and every workspace inherits it unless overridden. Reduces configuration duplication across hundreds of workspaces.
Infracost integration. Cost estimates appear inline during plan reviews. OPA policies can reference cost data directly — block any apply that would increase monthly spend by more than a set amount, for instance.
Limitations
Only supports Terraform and OpenTofu. No Pulumi, CloudFormation, or Ansible. If you run multiple frameworks, Scalr won’t consolidate them. Teams with very high run volumes (hundreds of applies daily) should model costs carefully against the per-run billing.
Pricing
Per-run billing with a free tier for testing. No per-user or per-resource fees. Published benchmarks suggest significant savings over HCP Terraform for teams managing 1,000+ resources with moderate change frequency.
Best For
Terraform/OpenTofu-only teams with medium-to-large resource counts wanting full governance without enterprise-tier pricing. Particularly strong for organizations migrating from HCP Terraform’s Standard or Premium tiers.
Atlantis: Self-Hosted, Free, Battle-Tested
Atlantis has been the default free option for Terraform PR automation since 2017. A Go binary you deploy yourself — listens for VCS webhooks, runs terraform plan on PRs, posts output as comments, applies when you comment atlantis apply. No SaaS dependency, no subscription, no vendor lock-in.
Why Teams Still Choose It
Zero software cost. Simple mental model — a webhook, a server, a config file. Full control over credentials and data residency. Eight years of community-documented solutions for edge cases.
The Scaling Wall
Atlantis was designed for small teams. As usage grows, several issues compound:
- Single-threaded concurrency bottlenecks with high PR volumes or monorepos
- No native RBAC — anyone who can comment can trigger applies
- No drift detection — only acts when PRs open
- Credential sprawl at 50+ workspaces becomes a maintenance burden
- Operational overhead typically runs 10-20 hours/month at larger organizations for upgrades, webhook debugging, and monitoring
Factor hidden costs honestly: if your platform engineer spends 15 hours/month maintaining Atlantis at $80/hour, that’s $1,200/month you’re not seeing on an invoice.
Best For
Small teams (under 10 engineers) managing fewer than 30 workspaces, with platform engineers willing to own the maintenance. Also works as a stepping stone before migrating to a managed platform.
Terrateam: Managed Atlantis Without the Ops Burden
Terrateam fills the gap between Atlantis and full SaaS platforms. It’s a GitHub App providing the same comment-driven plan/apply workflow, but fully managed — no server to deploy, no webhooks to configure, no upgrades to handle.
Strengths
GitHub-native. Installs in minutes. PR comments trigger plans, applies, and cost estimates. The entire workflow stays inside GitHub with no separate dashboard needed.
Multi-framework support. Despite the name, Terrateam supports Terraform, OpenTofu, CDKTF, Pulumi, and Terragrunt through the same interface.
Built-in cost estimation via their open-source OpenInfraQuote tool — cost projections posted directly in PR comments without needing a separate Infracost subscription.
Access control via YAML config tied to GitHub team structures. Define who can plan and who can apply per directory or workspace.
Limitations
GitHub only — no GitLab or Bitbucket support. Enterprise features (SSO, audit logging, compliance reporting) still maturing. No drift detection, no scheduled runs, limited dependency visualization. Smaller community and documentation footprint than established competitors.
Best For
Teams on Atlantis wanting to drop operational overhead without adopting a full platform. GitHub-centric organizations preferring IaC workflows inside the PR interface.

How to Choose
Work backward from your constraints rather than comparing feature lists:
How many IaC frameworks do you run? One (Terraform/OpenTofu only) points to Scalr or HCP Terraform. Two or more points to env0 or staying on Spacelift.
What’s your budget model? Fixed monthly budgets favor env0’s tier pricing or Scalr’s per-run model. Consumption-based budgets work with HCP Terraform’s per-resource approach. Zero budget means Atlantis or Terrateam’s free tier.
Do you need drift detection? If yes, realistic options are env0, Scalr, or HCP Terraform. Atlantis and Terrateam don’t offer it.
How mature is your platform team? No dedicated team favors managed SaaS (HCP Terraform, env0). Small team with some ops capacity fits Scalr or Terrateam. Large team that enjoys control can handle Atlantis.
Migration Tips
State backends usually don’t change — most teams use S3/GCS regardless of platform. Migration is about recreating workspace configs, variable bindings, and policy rules.
Start with one workspace. Run your smallest, least critical workspace on the new platform for two weeks. Verify plan output matches and approval workflows trigger correctly.
Budget 4-8 weeks for a team managing 50 workspaces. At 200+ workspaces, expect 8-12 weeks with a phased rollout by team or environment.
The Bottom Line
Spacelift remains strong for teams genuinely using multi-IaC orchestration across Terraform, Pulumi, and Kubernetes simultaneously. The concurrency pricing and tier-gated governance are the main reasons teams leave.
For Terraform/OpenTofu-only shops, Scalr delivers equivalent governance at lower, more predictable cost. For multi-framework environments, env0 matches Spacelift’s breadth without the concurrency ceiling. For budget-constrained teams, Atlantis still works if you absorb the maintenance, and Terrateam offers a managed middle ground.
Run trials on your actual workloads. The platform that generates fewer support tickets from your team is probably the right one.
