The policy-as-code engine is the standout feature for us — being able to define OPA-based policies to control who can approve and apply Terraform changes has greatly improved our governance over AWS infrastructure. Stack management is also solid, making it easy to organize and track deployments across multiple environments. The pull request preview feature is a big workflow win: engineers can see a Terraform plan directly in their PR before merging, which catches issues early and speeds up code review.

The documentation is the weakest area. For example, we struggled to find clear guidance on security best practices for setting up Spacelift across an org, specifically how to scope IAM permissions per stack so each stack has only the access it needs. This is a common requirement but the docs don't walk you through it in a practical way. Review collected by and hosted on G2.com.
