Terrateam is an open-source GitOps platform that automates Terraform, OpenTofu, and Pulumi deployments through GitHub pull requests. It handles large-scale infrastructure-as-code workflows with monorepo support, policy enforcement, and cost estimation, available as both a self-hosted and hosted SaaS offering.

What terrateam is
Written in OCaml, Terrateam integrates with GitHub to orchestrate IaC provisioning via pull request comments. It provides tag-based configuration, parallel execution with smart locking, OPA/Rego policy enforcement, drift detection, and a stateless self-hostable architecture designed for monorepos with complex workspace dependencies.

Best use cases
Implementation considerations
- Requires GitHub organization/repository setup and OAuth/token configuration; default deployment uses Docker Compose—assess whether self-hosting or SaaS aligns with your compliance posture.
- Tag-based configuration model requires upfront planning of workspace taxonomy and policy rules; monorepo migrations may need significant `.terrateam/config.yml` design work.
- Stateless design means state files and secrets remain external (your Terraform backend and GitHub Secrets); ensure backend and secret-manager integration is production-ready before pilot.
- Policy enforcement via OPA/Rego requires learning Rego syntax; consider training or hiring expertise if custom policy logic is needed beyond built-in approval workflows.
- Parallel execution relies on smart locking; verify your Terraform state backend supports concurrent operations and state locking (S3 + DynamoDB, Terraform Cloud, etc.).
When to avoid it — and what to weigh
- Simple single-workspace deployments — If you manage only a few environments or simple Terraform configurations, the overhead of GitOps orchestration and policy engines will likely exceed operational benefit.
- Non-GitHub version control systems — Terrateam is GitHub-native; no support for GitLab, Bitbucket, or other VCS platforms is mentioned in available documentation.
- Minimal operational overhead requirement — Self-hosting requires Docker Compose, runner management, and integration with your GitHub installation—not a turnkey solution for teams avoiding infrastructure operations.
- Proprietary IaC tools or custom CLIs only — While it claims to work with 'any CLI,' primary testing and documentation focus on Terraform, OpenTofu, and major tools; custom or proprietary provisioners may require custom integration work.
License & commercial use
Terrateam is licensed under MPL-2.0 (Mozilla Public License 2.0), a weak copyleft OSI-approved license. Source code modifications must be shared, but MPL-2.0 is file-scoped and allows proprietary derivative works if only modified files are shared.
MPL-2.0 permits commercial use of the software itself without royalty. However, enterprise features (RBAC, centralized configuration, Gatekeeper approval workflows) are explicitly reserved for the hosted SaaS and self-hosted Enterprise Edition under separate licensing. Verify licensing terms with the Terrateam team before assuming all features are available for your intended commercial deployment.

State and secrets remain external (user-managed backends and GitHub Secrets); Terrateam does not expose or store sensitive data internally. Self-hosting requires securing runner environments and GitHub token scope. RBAC and OIDC integration are available in Enterprise Edition; open-source version lacks built-in role enforcement. No public security audit or CVE history available; assess threat model and code review before production deployment in regulated environments.
Alternatives to consider
Terraform Cloud/Enterprise (HashiCorp)
Native, managed Terraform state, runs, and policy engine (Sentinel). Vendor-managed but tightly integrated; less monorepo-friendly and primarily Terraform-only.
Atlantis (open-source)
Lightweight, self-hostable Terraform PR automation. Simpler deployment and no OCaml dependency, but lacks native policy engine, cost estimation, and monorepo-scale features.
Spacelift (commercial SaaS)
Multi-tool orchestration, policy engine, and UI similar to Terrateam. Managed SaaS removes self-hosting burden but introduces vendor lock-in and higher cost at scale.
