CostMon vs. AWS Cost Explorer
AWS Cost Explorer is the native billing console built into every AWS account. Below, we compare it to CostMon and cover when each one is the better fit.
Native, single-cloud AWS billing console
AWS Cost Explorer is the cost visualization and reporting tool built into the AWS console. There is no separate sign-up and no extra vendor. It lets you view and filter historical AWS spend by service, account, tag, and time period. It is useful for ad-hoc AWS-only analysis.
Cost Explorer is a report you go and look at. CostMon is a normalized daily number that comes to you. It sits next to every other provider, AI included, instead of AWS alone.
Side by side
CostMon vs. AWS Cost Explorer, dimension by dimension
| Dimension | CostMon | AWS Cost Explorer |
|---|---|---|
| Provider coverage | AWS, GCP, and Azure for cloud. Anthropic, OpenAI, Amazon Bedrock, Vertex AI / Gemini, and Helicone for AI and LLM spend. Snowflake and Databricks for the data cloud. Datadog, GitHub, and Vercel for the rest of the stack. CSV import covers any other tool. All of these are live today, normalized into one view. | AWS only. Cost Explorer has no visibility into other clouds or SaaS spend. |
| AI / LLM spend | Five AI providers (Anthropic, OpenAI, Amazon Bedrock, Vertex AI / Gemini, and Helicone) normalized in the same daily view as AWS spend. | None. Cost Explorer only reports on AWS billing, not external AI provider spend. |
| Pricing | Flat monthly rate per plan. | Included with an AWS account. AWS also charges separately for its Cost Explorer API calls. |
| Workflow | Syncs on a schedule and shows a daily normalized total, without a separate console to open. | A console you open and query by hand, built for periodic review rather than a standing daily signal. |
| Cross-team visibility | One normalized number that finance and engineering both look at, across every connected provider. | AWS-account-scoped. Reconciling it against other providers' spend is a manual, separate exercise. |
| Seat / account model | One flat rate per plan covers the account. There is no per-seat or per-user charge to add teammates. | Included with the AWS account under IAM. IAM policies control access per user, so there is no separate seat count. |
| Alerting and anomaly detection | Anomaly rules flag a spike by source, service, or tag, across every connected provider. Budgets alert you at set thresholds. | AWS Cost Anomaly Detection is a separate, free AWS feature that you can pair with Cost Explorer, per AWS's own documentation. |
Where CostMon fits better
- One normalized view across AWS and every other provider you connect, cloud and AI alike
- A standing daily signal, not a console you must remember to open
- Flat pricing that does not change based on how AWS bills you
- One shared view for finance and engineering, not a console built for AWS-account-level query access
- No IAM policy work needed to get a cross-provider number in front of non-engineering stakeholders
When AWS Cost Explorer is the better choice
- Included with every AWS account at no extra product cost
- The authoritative, first-party source for AWS billing detail and cost allocation tags
- No third-party credential or connector setup, because it is already there
- The deepest AWS-specific detail: service, linked account, tag, and Reserved Instance and Savings Plan reporting
- Pairs natively with AWS Cost Anomaly Detection and AWS Budgets, both free AWS-native features
Bottom line
If AWS is your only provider and you only need to query historical spend now and then, Cost Explorer already does that for free. If you run AWS alongside other clouds, SaaS, or AI/LLM providers, CostMon gives you one daily number instead of separate consoles to reconcile by hand.
Before you decide
Questions worth asking before you choose
Is AWS your only provider, or do you also run other clouds, SaaS tools, or AI/LLM APIs?
Cost Explorer is free and authoritative for AWS-only spend. When a second provider enters the picture, reconciling it against Cost Explorer becomes a manual export-and-merge exercise. A normalized cross-provider view closes that gap.
Who needs to see this number: just the AWS account owner, or finance and other teams too?
IAM policy governs Cost Explorer access per user per account. That works well for engineers who already know the AWS console. A shared view for non-technical readers removes the IAM and console-navigation step for stakeholders outside engineering.
Do you want a report you query, or a signal that reaches you without opening a console?
Cost Explorer is built for ad-hoc queries against historical data. That is useful, but only when someone remembers to open it. A standing daily total changes the workflow from 'go check' to 'it is already in front of you.'
Are you already using AWS Cost Anomaly Detection and AWS Budgets?
Both are free and AWS-native, and both are worth using whatever else you adopt. They do not need Cost Explorer or any third-party tool. A cross-provider view on top does not replace them. It extends the same kind of signal to spend outside AWS.

FAQ
Common questions about CostMon vs. AWS Cost Explorer
Does CostMon replace AWS Cost Explorer?
Not exactly. CostMon reads from AWS Cost Explorer's data through a read-only connector. It normalizes that data next to every other provider you connect. AWS spend then sits in the same daily view as the rest of your stack, not in its own console.
Is AWS Cost Explorer free?
It is included with an AWS account. Per AWS's own pricing page, AWS charges separately for Cost Explorer API calls beyond the free console usage. CostMon charges a flat monthly rate per plan, regardless of API usage.
Can AWS Cost Explorer track Anthropic or other AI provider spend?
No. Cost Explorer only reports on AWS billing. CostMon normalizes AI/LLM provider spend (Anthropic, OpenAI, and three more AI providers) in the same daily view as AWS and other cloud spend.
Why use CostMon if Cost Explorer is already free?
Cost Explorer is a query tool scoped to one AWS account at a time. CostMon adds a daily, standing signal. It normalizes every provider you run, cloud and AI. Finance and engineering share one view, in place of a separate console for each provider.
Can we use CostMon and Cost Explorer together?
Yes. CostMon's AWS connector reads from the same underlying Cost Explorer data, so there is no conflict. Some teams keep Cost Explorer open for deep, ad-hoc AWS-only queries, such as tag-level drill-downs and RI or Savings Plan analysis. They use CostMon for the daily cross-provider number.
Does AWS offer its own anomaly detection I should compare against CostMon?
Yes. AWS Cost Anomaly Detection is a separate, free AWS-native feature that can flag unusual AWS spend by itself. It is AWS-only, like Cost Explorer. CostMon also ships anomaly rules and budgets, and they cover every connected provider. Many teams use both. CostMon does not replace AWS-native alerting.
