env0 vs OpenStack Heat

env0 is a cloud control plane for governing infrastructure and helping teams manage, automate, and scale it. Developers and AI agents deploy through reusable templates and Git-based workflows, with RBAC, scoped variables, and policy-as-code guardrails. It supports Terraform, Terragrunt, Pulumi, OpenTofu, Kubernetes, Helm, Ansible, and AWS CloudFormation across cloud accounts, Kubernetes resources, and IaC-managed environments. Drift management detects changes across clouds, plans fixes with blast-radius context, remediates at the infrastructure-as-code source, and rescans. Cloud Asset Management maps resources across clouds, accounts, and SaaS providers to owners, costs, dependencies, and policy state. Listed integrations include GitHub, GitLab, Bitbucket, Azure DevOps, AWS, Azure, GCP, Slack, Microsoft Teams, Datadog, and Backstage. The Free Tier costs nothing, billed Free / Forever, with up to 30 active environments, 250 monthly deployments, one concurrent run, unlimited users and agents, and community support. Custom-priced Cloud Navigator and Cloud Pilot plans are also listed.

OpenStack Heat is a free, open-source orchestration service for composite applications in OpenStack. Declarative templates describe infrastructure and relationships in human-readable files that can be version-controlled. Heat can create instances, floating IPs, volumes, security groups, and users, while supporting instance high availability, autoscaling, and nested stacks. It runs HOT templates written in YAML and also accepts AWS CloudFormation templates. Templates can integrate with Puppet and Ansible, and operators can extend capabilities with plugins. The service exposes an OpenStack-native REST API and a CloudFormation-compatible Query API. Access is available through a command-line interface, RESTful queries, and the OpenStack dashboard. Heat runs on Linux as a self-hosted service and is provided under the Apache 2.0 license. Installation assumes an existing OpenStack environment with Compute, Image Service, and Identity, with guidance covering Red Hat Enterprise Linux, CentOS, Ubuntu, and Debian.
