Community Support: On Reddit, users who switched from Atlantis to Spacelift report a much cleaner and more manageable experience, especially in terms of PR noise and log visibility
Labeling and Organization: Features like labels and Spaces help teams organize infrastructure projects efficiently, which is especially useful in large or multi-team environments
Modern UI and Workflow Design: The interface and workflow customization are seen as modern and intuitive, especially compared to older tools like Atlantis
Ease of Use: DevOps engineers appreciate how easy it is to connect Spacelift to cloud providers like AWS. Once credentials are set, the platform handles much of the heavy lifting
Policy-as-Code: Many users highlight the value of Spacelift’s policy engine using Open Policy Agent (OPA), which helps enforce compliance and governance standards during deployments
Terraform Integration: Users consistently praise Spacelift for its deep integration with Terraform. It enhances visibility and control over infrastructure changes, especially through pull request-based workflows that show plan and apply logs directly in the PR
Not Ideal for Small Teams: A few reviewers suggest that Spacelift’s full value is best realized in organizations with more than 500 employees, implying it may be overkill for smaller teams
Kubernetes Sync Issues: There have been occasional complaints about synchronization issues when using different versions of Kubernetes or HashiCorp tools
Self-Hosted Limitations: The self-hosted version is reported to have fewer features than the SaaS version, particularly in terms of integrations with Azure and GCP
Complex Deployments: Some users note that Spacelift may not be ideal for very complex or large-scale deployments that require advanced coordination features
Limited Free Tier: The free version lacks some essential features, such as deployment notifications, which can be a drawback for small teams or those evaluating the platform
