If your team runs Terraform (or OpenTofu) together, at some point you hit the same wall: someone needs shared remote runs, a private module registry, and access control — the things Terraform Cloud or Terraform Enterprise sell. Two free, open-source, self-hosted projects both go after that exact gap: Terrakube and Terrapod. They even list each other as direct alternatives in their own comparison data. Here's how they actually differ.
Side by side
| Terrakube | Terrapod | |
|---|---|---|
| Maturity | ~950 GitHub stars, 2,200+ commits — the most established open-source option | 253 GitHub stars — young, needs careful evaluation before critical use |
| Deployment | Kubernetes (Helm) or Docker Compose — flexible | Kubernetes cluster required — no Docker Compose path |
| Terraform Enterprise compatibility | Its own API and workflow, not a drop-in replacement | Compatible with the Terraform Enterprise API V2 — minimal workflow changes migrating off HashiCorp |
| SSO | Broad: Azure Entra ID, Google, AWS Cognito, GitHub, Keycloak, OIDC, SAML | Not a headline feature — focus is on RBAC and policy instead |
| Credentials | Dynamic cloud credentials for AWS/Azure/GCP/Vault — no static secrets | Workload identity — also no static cloud credentials to protect |
| Built-in extras | OPA policy-as-code and Infracost cost estimation, integrated | Versioned state with lock/rollback, RBAC, OPA, signed private registry (GPG) |
| Pricing | Free, open source (Apache 2.0) | Free, open source (MPL-2.0, same license as OpenTofu) |
Terrakube: the established, flexible-deployment option
Terrakube is the more mature project by a wide margin — roughly 950 GitHub stars and over 2,200 commits, making it the most established name in this specific open-source niche. It supports a genuinely broad range of single sign-on providers (Azure Entra ID, Google, AWS Cognito, GitHub, Keycloak, and standard OIDC/SAML), which matters if your team already has an identity provider you don't want to work around. It also bakes in OPA policy-as-code and Infracost cost estimation directly, and issues dynamic, short-lived cloud credentials instead of storing static secrets. You can deploy it via Kubernetes/Helm or plain Docker Compose, which is more flexible than a Kubernetes-only requirement.
Limites: self-hosting is mandatory — there's no managed cloud tier the way Terraform Cloud offers a free hosted plan — so you own all the operations, upgrades, and backups. If running a dedicated server at all feels heavy for your team, lighter tools like Atlantis or Digger (which run inside your existing CI instead) are worth a look before committing to Terrakube.
Terrapod: built to be a drop-in for teams leaving Terraform Enterprise
Terrapod's distinguishing feature is compatibility: it implements the actual Terraform Enterprise API V2, so a team migrating off HashiCorp's paid product can expect to change very little in how they already work. It covers the same core ground — versioned state with locking and rollback, RBAC, OPA policy-as-code, and a private module registry with GPG-signed packages — plus workload identity instead of static, long-lived cloud credentials. It only runs on Kubernetes, with no Docker Compose option.
Limites: it's a young and comparatively small project (253 GitHub stars next to Terrakube's ~950), so it's less proven running critical infrastructure state at scale — evaluate it carefully, and don't hand it your most important state files without testing first. It also requires a Kubernetes cluster to self-host at all; there's no lighter deployment path and no managed SaaS version.
Which should you pick?
Pick Terrakube if you want the more established, battle-tested option, need broad enterprise SSO out of the box, or want the flexibility of deploying via Docker Compose instead of standing up Kubernetes.
Pick Terrapod if you're specifically migrating away from a paid Terraform Enterprise contract and want the closest API-level match to minimize workflow disruption, and you already run Kubernetes.
Both are free and open source, so the real cost is operational: someone on your team owns uptime, upgrades, and backups either way — unlike Terraform Cloud's own hosted free tier. If that operational cost doesn't clearly pay off yet, it's also worth comparing against CI-native tools like Atlantis or Digger before picking either.
