Free AWS Cost Optimization Tool
Scan your AWS account for idle resources, oversized instances, and cost anomalies. Get exact fix commands with dollar amounts. Results in 2 minutes. No credit card.
Every type of AWS waste,
caught and priced.
Real dollar amounts from real production scans. Not estimates. Not projections.
Idle and zombie resources
EC2 instances with near-zero CPU. RDS databases with zero connections. Unattached EBS volumes running for 1,790+ days. Resources you forgot about but keep paying for.
Oversized infrastructure
Lambda functions allocating 1,024 MB but using 190 MB. NAT Gateways processing thousands of gigabytes when VPC Endpoints would cost 80% less.
Missing migrations
EBS volumes still on GP2 that should be GP3. EC2 instances on previous-generation types. Lambda functions on x86 that could run on ARM64 for 20% less.
Cost anomalies
Spend spikes caught via statistical baselines. Runaway growth detected in hours, not quarters. Budget overruns flagged before the bill arrives.

2-minute setupWe scan for waste and anomalies
111 detection rules find idle resources, oversized instances, and wasted spend. Anomaly detection catches cost spikes and runaway growth.

These are actual CostPatrol scans on production AWS accounts. Names anonymized, savings real.
Works across every AWS region.
Used by teams worldwide.
US regions
Full coverage for us-east-1 (N. Virginia), us-east-2 (Ohio), us-west-1 (N. California), and us-west-2 (Oregon). Most US-based AWS accounts run workloads across multiple US regions. CostPatrol scans all of them in parallel and catches waste that single-region tools miss.
EU and UK regions
Complete scanning for eu-west-1 (Ireland), eu-west-2 (London), eu-central-1 (Frankfurt), eu-north-1 (Stockholm), and all other EU regions. European teams with GDPR-driven multi-region setups often have the most scattered waste. CostPatrol finds it all.
Multi-region cost anomalies
Cost spikes don't respect region boundaries. A recursive Lambda in us-east-1 can trigger NAT Gateway charges in eu-west-1 through cross-region API calls. CostPatrol's anomaly detection works across all regions simultaneously, catching spend spikes wherever they originate.
No region left behind
Most teams only check their primary region. CostPatrol scans every enabled region in your account. That forgotten ap-southeast-1 test cluster? The idle NAT Gateway in ca-central-1? Found. Priced. Fix command ready.

CostPatrol scans 30+ AWS services including Lambda, EC2, EBS, S3, RDS, Aurora, DynamoDB, CloudWatch Logs, NAT Gateway, ECS, EKS, Elastic IPs, and more. It checks for idle resources, oversized instances, missing storage lifecycle rules, previous-generation types, unattached volumes, and cost anomalies across all services.
Trusted Advisor gives vague recommendations like "consider rightsizing." CostPatrol gives you the exact resource ARN, a dollar savings range, and a copy-paste CLI command. Trusted Advisor results sit in the AWS console with a 24-hour delay. CostPatrol delivers ranked findings to Slack daily. Trusted Advisor's free tier covers 5 basic cost checks. CostPatrol runs 111 rules across 30+ services.
CostPatrol is read-only. It connects via a CloudFormation-deployed IAM role with strictly read-only permissions. It can describe and list resources, but never create, modify, or delete anything. The fix commands are for you to review and run. CostPatrol never touches your infrastructure.
Under 2 minutes. CostPatrol scans all enabled regions in parallel. In real scans, we found $284/month in a single region in under 60 seconds, and $6,496/month across 4 regions in under 2 minutes.
Enterprise tools charge $1K-$10K+/month with per-seat licensing. CostPatrol starts free and scales with your AWS spend, not headcount. Every finding includes a copy-paste CLI fix command. Results go to Slack, not a dashboard you'll forget about. No multi-week onboarding. Connect in 2 minutes, see savings immediately.
Yes. CostPatrol scans every AWS region your account has enabled. This includes all US regions (us-east-1, us-east-2, us-west-1, us-west-2), EU regions (eu-west-1, eu-west-2, eu-central-1, eu-north-1, eu-south-1), and all other global regions. It scans them in parallel, so a multi-region account still completes in under 2 minutes. Most waste hides in secondary regions that teams forget about.
AWS Cost Explorer shows you what you spent. CostPatrol shows you what to stop spending. Cost Explorer gives you charts and breakdowns. CostPatrol gives you the specific resource ARN, the dollar amount you're wasting, and the exact CLI command to fix it. Cost Explorer charges $0.01 per API request for programmatic access. CostPatrol's free tier includes everything with no per-request fees.
Yes. CostPatrol does not rely on resource tags to find waste. It uses real-time metrics. Idle EC2 is identified by CPU utilization, not tags. Unattached EBS volumes are found by attachment state, not naming conventions. Oversized Lambda functions are caught by comparing allocated memory to actual usage. This means CostPatrol works on any AWS account, even those with no tagging strategy.
