AWS cost monitoring

Catch AWS overspend before the invoice does

CostMon connects to AWS Cost Explorer and turns your raw billing data into a daily, normalized view that finance and engineering both trust — so a runaway service gets caught in days, not discovered at month-end.

AWS Cost Explorer — live today

AWS Cost Explorer shows you spend, but not urgency — it's built for monthly review, not for catching a forgotten NAT gateway or an idle GPU fleet while it's still cheap to fix. By the time a cost anomaly shows up on the invoice, it's already weeks old and the spend is sunk. Finance sees a lagging number; engineering has no daily signal to act on.

Why CostMon

Built for AWS spend, from day one

Daily, not monthly

CostMon syncs AWS Cost Explorer data on a schedule and gives you a live daily total instead of a static end-of-month report, so a climbing line is visible while there's still time to act.

Runaway and idle spend, surfaced

Normalized service- and account-level breakdowns make it obvious when a forgotten resource or a scaling mistake is quietly costing you every day, not just once a month.

One number for finance and engineering

Stop reconciling Cost Explorer exports against a spreadsheet. Everyone looks at the same normalized total, broken down the same way, refreshed on the same schedule.

Read-only, cost-scoped credentials

CostMon connects with AWS credentials scoped to Cost Explorer billing data only — read-only, and it never touches your workloads or infrastructure.

FAQ

Common questions about the AWS connector

How does CostMon connect to AWS?

Through a read-only AWS Cost Explorer connector, scoped to billing data only. CostMon never requests access to your workloads, source code, or production infrastructure.

Does CostMon replace AWS Cost Explorer?

No — CostMon reads from Cost Explorer and normalizes it alongside every other provider you connect (Anthropic, and more rolling out continuously), so AWS spend sits in the same daily, normalized view as the rest of your stack instead of its own separate console.

How often does AWS cost data sync?

CostMon's background scheduler syncs AWS Cost Explorer data on a regular cadence so the dashboard reflects a daily view, not a monthly snapshot.

Can I see AWS costs broken down by service or account?

Yes — costs sync in with their service and account detail intact, so you can see trends by provider, by service, or grouped into cost buckets by team or project.

What does the AWS connector cost?

A flat monthly rate per plan — never a percentage of your AWS bill or the savings CostMon helps you find. Free includes 2 connectors; Professional and Enterprise include unlimited connectors.
