GitOps is a methodology that uses Git repositories as the single source of truth for software development and infrastructure management.GitOps tools automate software delivery using declarative configuration, IaC, and CI/CD, following GitOps principles.Top GitOps tools include Spacelift, Argo CD, Flux CD, Codefresh, GitLab, Terraform, OpenTofu, and Werf.Spacelift automates IaC workflows, supports various technologies, and includes drift detection capabilities.Argo CD offers continuous delivery for Kubernetes, syncing manifests from Git repositories to clusters.Flux CD provides fully automated state reconciliation with integration options for cloud providers.Codefresh is an enterprise-scale SaaS GitOps solution with monitoring dashboards and debugging support.Terraform, known for IaC, extends GitOps to infrastructure configuration allowing automated changes based on repository content.OpenTofu, an open-source alternative to Terraform, enables syncing of infrastructure state with repository content.Werf is a CI/CD system automating application delivery to Kubernetes clusters based on Git repositories.
