Product video
Gruntwork Platform for AWS is a multi-account AWS foundation that platform and DevOps teams own as code. It sets up AWS Organizations, AWS Control Tower and IAM Identity Center, vends new accounts through pull requests, and runs every infrastructure change through a GitOps pipeline. It works in new and existing AWS environments and follows practices from AWS' Well Architected Framework.
Gruntwork created Terragrunt and is a founding member of OpenTofu. Our co-founder wrote Terraform: Up & Running.
What's included:
- Landing Zone architecture: an AWS Organizations structure with separate accounts for security, logs, shared services and workloads. Account baselines turn on AWS Config, AWS CloudTrail, Amazon GuardDuty, AWS Security Hub, Amazon Macie and IAM Access Analyzer, with Service Control Policies as guardrails.
- Networking: Amazon VPCs, subnets and route tables in each account, with AWS Transit Gateway for hub networking and shared services.
- Gruntwork Account Factory: request a new AWS account with a pull request. It arrives with baselines and guardrails already applied.
- Gruntwork Pipelines: plans run when a pull request opens and applies run on merge, in your own GitHub Actions or GitLab CI runners.
- Pipelines Hooks: checks that run after every plan or apply and post results in the pull request. Built-in hooks include AI Plan Summary, Infracost cost estimates, Trivy and Checkov security scanning, Open Policy Agent policy enforcement and apply status labels. AI Plan Summary explains each plan in plain language and flags risky changes such as destroyed resources. Hooks can warn reviewers or block a merge.
- Drift Detection: scheduled and on-demand scans open a pull request when deployed resources no longer match your code.
- Patcher: automated updates for OpenTofu and Terraform modules and Terragrunt units and stacks, including breaking changes.
- Module library: 230+ maintained OpenTofu and Terraform modules for services such as Amazon EKS, Amazon ECS, Amazon Aurora and AWS Lambda.
- AI Infrastructure Delivery: the Gruntwork Library MCP Server and repo rules files give AI coding agents your modules and conventions. Agents open pull requests, and Pipelines applies the same policy and approval gates it applies to people.
- Guided setup: hands-on help to stand up the landing zone, the repo structure with Terragrunt stacks, Account Factory and Pipelines.
How teams use it:
- Multi-account foundation: move to a multi-account setup or adopt AWS Control Tower without building it from scratch.
- Migration readiness: get the landing zone ready so migrations and new workloads, such as Amazon EKS platforms, can start.
- ClickOps to infrastructure as code: bring existing AWS environments under code and review.
- Compliance groundwork: CIS AWS Foundations Benchmark baselines, SCPs and AWS Config Rules support SOC 2, PCI DSS, HIPAA, HITRUST and NIST programs.
- Leaving Terraform Cloud or Terraform Enterprise: run OpenTofu or Terraform with Terragrunt in your own CI.
- AI-assisted delivery: teams adopting AI-DLC get agents that build from approved modules, with every change reviewed.
Easygo grew from 10 to over 100 AWS accounts with consistent governance and cut pipeline maintenance by about 90 percent with Gruntwork Pipelines and Terragrunt.
You own all the code. Everything is OpenTofu or Terraform in your own repositories, with no lock-in.
Highlights
- Landing Zone in days: a production-ready, multi-account AWS landing zone with AWS Control Tower, IAM Identity Center, networking and security baselines, delivered as OpenTofu and Terraform code your team owns in your own AWS accounts.
- Run by a small team: Easygo grew from 10 to over 100 AWS accounts with consistent governance and cut pipeline maintenance by about 90 percent with Gruntwork Pipelines and Terragrunt. Account Factory, Drift Detection and Patcher keep accounts, modules and pipelines current.
- Ready for AI-assisted delivery: AI agents build from your approved modules and conventions through the Gruntwork Library MCP Server. AI Plan Summary explains every plan in the pull request and flags risky changes, and each change is policy-checked and approved before it reaches AWS.

Standardized terraform practices have reduced deployment time and simplified AWS environments
What is our primary use case?
The main use case for Gruntwork AWS Terraform Module Libraries & Reference Architecture is to standardize how our AWS infrastructure is provisioned using Terraform. As our engineering team started managing multiple AWS accounts and environments, we realized that every project was maintaining its own Terraform codebase with slightly different implementations for common resources such as VPCs, IAM roles, security groups, and others. This created an operational challenge for us. Infrastructure was difficult to maintain, and updates had to be repeated across repositories. We were facing many problems, and there was always a risk of configuration drift between all the environments. We adopted Gruntwork, and it helped us establish reusable, production-ready Terraform modules and reference architectures so that new environments could be deployed consistently without rewriting infrastructure code.
A specific example of how we used Gruntwork in a project is when provisioning a new application environment. We no longer create networking components from scratch. We simply consume standardized modules for Amazon VPC, public and private subnets, NAT gateways, internet gateways, security groups, and everything else. This has significantly reduced the deployment time and improved the consistency across the environments.
How has it helped my organization?
Gruntwork AWS Terraform Module Libraries & Reference Architecture has positively impacted our organization as we noticed a practical benefit in less time writing Terraform. Instead of developing every infrastructure component manually, we maintain focus on configuring variables and integrating existing modules. The infrastructure reviews are easier because projects follow similar structures, and reviewing Terraform changes is much simpler. Disaster recovery is faster as well. When an environment needs to be recreated, standardized Terraform modules allow us to provision infrastructure very quickly.
Regarding specific outcomes or metrics, we save most of the time since adopting Gruntwork, which I estimate to be approximately thirty percent of the time.
What is most valuable?
The best features Gruntwork AWS Terraform Module Libraries & Reference Architecture offers include providing mature, reusable Terraform modules rather than requiring every organization to build and maintain its own library. It has reference architectures that provide a solid starting point for deploying a secure AWS environment. Infrastructure standardization, where every AWS environment follows the same deployment approach, reduces the maintenance burden. Whenever improvements are made to shared modules, multiple projects benefit without each repository needing a completely separate implementation, and this enables faster infrastructure delivery.
The feature that has had the most impact for our team is the production-ready Terraform modules. With this, different engineering teams now deploy infrastructure using the same standards. This has reduced the inconsistencies that previously appeared when projects were built independently.
What needs improvement?
Gruntwork AWS Terraform Module Libraries & Reference Architecture can be improved in that the module update process is somewhat of a pain point. As modules evolve, upgrading existing environments sometimes requires careful planning and compatibility testing. A more streamlined upgrade experience would be beneficial. Additionally, documentation of advanced scenarios would help. The documentation is comprehensive for common deployments, but more advanced enterprise examples involving hybrid networking, multiple region architectures, or complex IAM integration would be helpful.

For someone who is looking to mature their Terraform practices and is aiming to reduce infrastructure maintenance and establish a reusable AWS deployment framework, they can directly consider Gruntwork AWS Terraform Module Libraries & Reference Architecture. I would rate Gruntwork AWS Terraform Module Libraries & Reference Architecture a nine out of ten based on the scenarios and pain points I have shared. I did not purchase Gruntwork AWS Terraform Module Libraries & Reference Architecture through the AWS Marketplace.
Which deployment model are you using for this solution?
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Infrastructure as code has boosted multi-account deployments but needs less tool lock-in
What is our primary use case?
The main use case for Gruntwork AWS Terraform Module Libraries & Reference Architecture is to create a VPC, as well as EKS, RDS, S3 applications, and have all these Terraform states in an S3 bucket so that it's maintained, with the whole infrastructure maintained.
What is most valuable?
The best features of Gruntwork AWS Terraform Module Libraries & Reference Architecture are that they offer production-grade option modules that are available for everything I can think of, such as VPC, EKS, RDS, ALB, NLB, or any Lambda functions, as well as the Terragrunt-first architecture, which emphasizes that DRY configs are there, remote states, and multiple account deployment can be used with that. It also maintains security best practices, including default IAM, least privileged right access, secure networking, logging, auditability, and CIS controlled network.
Gruntwork AWS Terraform Module Libraries & Reference Architecture has positively impacted my organization, as previously things were done manually, but now we have everything in place. All the Terraform configurations are in the form of infrastructure as code that's available.
I find Gruntwork AWS Terraform Module Libraries & Reference Architecture very good for easier management, as our whole infrastructure is there in the form of code. There are fewer chances of error because everything is in a formal structure, infrastructure as code, which can be reviewed by other people as well. The production speed and the deployment speed are quite high; if anything comes up, we don't need to go and check it. We can just write a module inside it, and it will create that thing using the other modules that are there.
What needs improvement?
Gruntwork AWS Terraform Module Libraries & Reference Architecture should have less Terragrunt lock-in, as it's heavily tied to Terragrunt. AWS is moving very fast, and with AWS bringing your own EKS cluster, those new things that are coming immediately can be modulated inside Gruntwork. With the fast pace of AWS, Gruntwork should keep up and keep on developing those modules.
For how long have I used the solution?
I have been using Gruntwork AWS Terraform Module Libraries & Reference Architecture for the past two years, and I have worked with Gruntwork AWS Terraform modules.
What do I think about the stability of the solution?
Gruntwork AWS Terraform Module Libraries & Reference Architecture is very much stable.
What do I think about the scalability of the solution?
Gruntwork AWS Terraform Module Libraries & Reference Architecture's scalability is very high; for different environments, we can just mention it there, and it can handle all those environments.
How are customer service and support?
Customer support for Gruntwork AWS Terraform Module Libraries & Reference Architecture is really nice, as there are a lot of people outside of customer support who can answer questions and who are using this application.
Which solution did I use previously and why did I switch?
We previously used Terraform before adopting Gruntwork AWS Terraform Module Libraries & Reference Architecture. It helps in multi-cloud as well as multi-region developments, QA, and everything in between. Terraform works on a single module, so we moved to Gruntwork AWS Terraform Module Libraries & Reference Architecture.
What about the implementation team?
We can use the same Gruntwork AWS Terraform Module Libraries & Reference Architecture modules again and again without needing to change a lot of things, and Gruntwork helps with that. Multi-account AWS foundations, such as AWS Organization and Control Tower, provide us with very good support for those things.
What was our ROI?
I have seen a return on investment with Gruntwork AWS Terraform Module Libraries & Reference Architecture, as fewer employees are needed. We don't need anyone else; we can have everything as infrastructure as code. Money is saved because we don't need to make sure that things are decommissioned; we can just decommission it using the infrastructure as code. We can override what we want and don't want, and things go out.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing for Gruntwork AWS Terraform Module Libraries & Reference Architecture is that it's free as it's open-source. Licensing is also free to use with the open-source modules, so it's pretty much easy, and that's why we moved to it.
Which other solutions did I evaluate?
Before choosing Gruntwork AWS Terraform Module Libraries & Reference Architecture, I did not evaluate other options, as moving from Terraform to Terragrunt was pretty much easy, so we moved with this.
What other advice do I have?
My advice for others looking into using Gruntwork AWS Terraform Module Libraries & Reference Architecture is to go ahead with it, as it's really helpful. When people first start using it, they will get a better grip on it. It's also a coding language, so it's pretty simple if you have a basic coding understanding.
