Top 10 Atlantis Alternatives for 2024

Atlantis is an open-source automation tool that enhances the PR workflow for OpenTofu, Terraform, and Terragrunt projects. However, it has limitations such as workflow complexity, lack of direct mapping between projects and branches/tags, no robust policy framework integration, no private registry, complex configuration process, and no drift detection. Spacelift is an alternative to Atlantis that allows you to build powerful workflows for OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Ansible, and Kubernetes. It offers policies based on the OPA framework, supports third-party tool integration, enables sharing outputs between configurations, and provides features like drift detection and cost estimation. Other alternatives include Terraform Enterprise, Jenkins, GitHub Actions, Azure DevOps, GitLab CI/CD, Env0, Scalr, Morpheus, and Azure Automation.
