For an internal self-review, the AWS Well-Architected Tool in the console is free, official, and the right starting point. For a Terraform-native automated review with a client-deliverable PDF, ArchGuard covers that use case from $49/month. For an enterprise-grade review with stakeholder facilitation and the AWS credit incentive, an AWS Partner-led review is the right choice. “Best” depends entirely on who is receiving the output and what you intend to do with it.
How we compared these approaches
Each approach was evaluated across: pricing (public, verifiable), whether it reads IaC or requires human input, the pillar coverage across the six AWS Well-Architected pillars, the output format and intended audience, turnaround time, and whether an AWS account or credentials are required.
Disclosure: The author of this guide works on ArchGuard, listed at #5. ArchGuard is not at #1. AWS official tools are listed first because they are the baseline for any Well-Architected work, regardless of what commercial tools you add on top. All competitor descriptions are based on public documentation.

1. AWS Well-Architected Tool — the official baseline
Official AWS service · Free · Requires AWS account
What it does
The AWS Well-Architected Tool is an interview-driven service inside the AWS Console. You register a workload, answer approximately 50 questions across the six pillars (Security, Reliability, Cost Optimization, Operational Excellence, Performance Efficiency, Sustainability), and the tool surfaces the applicable best-practice guidance and high-risk issues for your self-reported answers.
Pricing
Free. No additional AWS charges beyond the account itself.
Limitations
The WA Tool does not read your Terraform, CloudFormation, or any IaC. Findings are based entirely on self-reported answers. The quality of the output depends on the accuracy and depth of your answers. It produces a console dashboard, not a PDF you can share outside the AWS account without manual export.
Best for
Every team running a workload on AWS. The AWS WA Tool is the baseline for all WAFR work and the instrument required for AWS Partner Network submissions. Use it first; supplement with other tools where it leaves gaps.

2. AWS Partner-led Review — the credit-eligible facilitated review
AWS Partner-facilitated · Free + optional $5K credit · Requires AWS account
What it does
An AWS Partner-led review is a Well-Architected Framework Review conducted by an AWS Partner consulting firm. The Partner facilitates the review with your team using the AWS Well-Architected Tool, documents all findings, and creates an improvement plan. Workloads that complete a qualified Partner review with a documented improvement plan can receive up to $5,000 in AWS Credits through the Well-Architected Partner program.
Pricing
Most AWS Partners offer a Partner-led review at no charge in exchange for the opportunity to propose follow-on services. The credit incentive (up to $5K) is paid to the AWS account, not to the customer in cash.
Best for
AWS customers with an existing AWS Partner relationship who want a facilitated review and are interested in the credit incentive. The credit incentive requires completing an improvement plan — it is not simply for undergoing a review.
3. AWS Well-Architected IaC Analyzer — the open-source self-hosted option
Open source · Free + Bedrock usage · Requires your AWS account
What it does
The AWS Well-Architected IaC Analyzer is an open-source tool published by AWS that analyzes Terraform, CloudFormation, and CDK against Well-Architected best practices using Amazon Bedrock. It is self-hosted in your own AWS account. Findings appear in a web UI; PDF export requires additional steps.
Pricing
Free to use (open source). You pay for Bedrock API calls and any AWS infrastructure you deploy to run it. Bedrock pricing varies by model; a typical IaC analysis session costs a few dollars in Bedrock usage.
Best for
Internal teams that want to run Terraform-aware WAF analysis without sending code to an external service. Requires comfort with self-hosting. The setup overhead (Bedrock access, CDK deployment) is higher than using a managed service.

4. Boutique consulting engagement — the human-led option
Specialist consulting · $5K–$25K · Requires AWS account access
What it does
A boutique consulting engagement is a bespoke Well-Architected review conducted by a specialist AWS consultant. The consultant reviews your architecture (typically through a combination of IaC analysis, live account review, and team interviews), documents findings, and produces a custom deliverable tailored to your workload and stakeholders. The output quality depends heavily on the consultant’s experience and the workload’s complexity.
Pricing
Typically $5,000–$25,000 depending on workload complexity, number of pillars, and the deliverable format. Fixed-price engagements are available from some consultants for well-defined scopes.
Best for
Complex multi-account, multi-region workloads where architectural judgment and stakeholder facilitation matter as much as the findings themselves. Pre-M&A due diligence where the acquirer requires a specialist attestation.

5. ArchGuard — best for consultant-deliverable Terraform reviews
Commercial SaaS · $49–$399/mo · Disclosure: this is our product
What it does
ArchGuard reads your Terraform HCL directly and produces a branded PDF report with findings mapped to the AWS Well-Architected Security, Reliability, Cost Optimization, and Operational Excellence pillars. No AWS account access required; no state files accepted; no infrastructure is modified. Turnaround is 24 hours from upload.
Pricing
Solo $49/mo, Team $149/mo, Agency $399/mo, Credit Packs $199 (3 reviews) / $499 (10 reviews). Full pricing.
Limitations
ArchGuard covers four of the six AWS Well-Architected pillars: Security, Reliability, Cost Optimization, and Operational Excellence. Performance Efficiency and Sustainability are not currently covered. ArchGuard is not an AWS Partner product and cannot submit workloads for AWS Partner credit.
Best for
Consultants delivering Well-Architected reviews to clients (white-label PDF with client branding on the Agency plan). CTOs who need a structured infrastructure review without giving AWS account access to a third party. Pre-DD preparation where a formal PDF is required in the data room. Not a replacement for an AWS Partner review or a consulting engagement where stakeholder facilitation is required.
6. Specialist WAFR tools
Various pricing and personas
A handful of specialist tools have emerged for specific WAFR use cases:
- 6pillars.ai — an AI-assisted Well-Architected review tool focused on the interview-driven approach with automated question generation.
- Stratus10 — a managed service provider that delivers Well-Architected reviews as part of a broader AWS management offering.
- nOps — a cloud operations platform with a Cost Optimization and Well-Architected review module, primarily targeting FinOps use cases.
Each of these serves a specific persona and pricing model. The right choice depends on whether you need WAFR as a standalone product, a module within a broader managed service, or as part of a FinOps platform.

Frequently asked questions
What is the AWS Well-Architected Tool?↓
The AWS Well-Architected Tool is a free, interview-driven service in the AWS Console. You answer approximately 50 questions about your workload across the six Well-Architected pillars; the tool records your answers and surfaces the applicable best-practice guidance. It does not read your Terraform or CloudFormation source — findings are based entirely on your self-reported answers.
What is an AWS Partner-led Well-Architected Review?↓
An AWS Partner-led review is a Well-Architected Framework Review conducted by an AWS Partner (typically a consulting firm) using the AWS Well-Architected Tool. The Partner facilitates the review with your team, documents findings, and can submit the workload for an AWS Partner credit (up to $5,000 in AWS credits if the workload meets the improvement plan criteria). The credit incentive is a program benefit of the AWS Partner Network, not a cash payment.
Does ArchGuard replace the AWS Well-Architected Tool?↓
No. The AWS Well-Architected Tool is free, is the official AWS instrument, and is required for Partner Network submissions. ArchGuard reads Terraform directly and produces evidence-based findings — it complements the AWS WA Tool rather than replacing it. ArchGuard output can accelerate a WA Tool session because the findings give you pre-prepared answers to many of the WA Tool questions.
How much does a boutique AWS consulting engagement cost?↓
Boutique AWS consulting engagements for a Well-Architected review typically range from $5,000 to $25,000 depending on workload complexity, number of pillars covered, and the deliverable format. Some consultants offer fixed-price engagements; others bill by the day or week. The fee pays for human judgment, stakeholder facilitation, and a custom deliverable — not just a tool run.
What is the AWS Well-Architected IaC Analyzer?↓
The AWS Well-Architected IaC Analyzer is an open-source tool (available at github.com/aws-samples/well-architected-iac-analyzer) that analyzes Terraform and CloudFormation against Well-Architected best practices using Amazon Bedrock. It is self-hosted, free, and requires your own AWS account and Bedrock access. It produces findings in a web UI; PDF export requires additional configuration.
