IaC Bazaar vs Terraform Registry
Public module registry · Terraform Registry site
The free, ubiquitous community catalog where anyone can publish a module.
What Terraform Registry is
A free, open public registry: anyone publishes a module from a public GitHub repo via semver git tags, and anyone consumes at no cost. There is no per-module verification pipeline; Official/Partner/Community labels denote WHO maintains a module, not whether it works.
Pricing
Free. (A private registry exists only inside the separately-priced HCP Terraform / Terraform Enterprise.)
Coverage
Every provider - roughly 4,000+ total (official, partner, and community). Breadth is enormous but coverage and quality vary wildly, with no uniform gate.
Where IaC Bazaar wins
- Proof, not a maintainer badge: we statically validate AND live-test modules (really applied, verified, then destroyed in a cloud account) and cosign-sign them with published evidence. The Registry runs no per-module apply/destroy testing or signing.
- HashiCorp removed the "verified" tag; the remaining Official/Partner labels denote who maintains a module, not whether it works. Community modules (where most modules live) carry no quality signal at all.
- A curated, consistent quality bar vs. an unmoderated firehose. We also cover Terraform/OpenTofu AND Ansible; the Registry is Terraform-only and GitHub-locked for publishing.
- A public, no-auth catalog API exposes every module’s verification status to AI agents; the Registry runs no verification pipeline, so there is no validated/applied/signed status to pull. Note the limit of that claim: it covers the verification evidence, not the input/output schemas - reading those here needs a signed-in account (a free one covers the free band).
Where Terraform Registry leads
- Free - a $0 incumbent our paid tiers must justify (our own free tier narrows this).
- Reach and defaults: it is the registry Terraform points at out of the box, with massive adoption and mindshare.
- Catalog size: the sheer number of modules and providers dwarfs any curated marketplace.
- Official and Partner modules for big-name products carry HashiCorp/vendor brand trust.
- Wide-open schemas: the Registry shows any module’s inputs and outputs to anyone, no account required. We put the input/output contract behind sign-in because the verification behind it is what we sell - if all you want is to read a schema, the Registry is the more open option, and we would rather say so than pretend otherwise.
The honest take
The Terraform Registry is the free, ubiquitous community catalog most teams already know - but WHO maintains a module (Official/Partner/Community) is the only trust signal, not whether it works. IaC Bazaar is the verified alternative: statically validated, many live-tested (applied, verified, then destroyed in a real account), and cosign-signed with published evidence, across Terraform/OpenTofu and Ansible.
