Cloud CORE, AWS cost calculator.

AWS Cost Optimization Resource Explorer (CORE).
Unlike your AWS bill or the AWS Cost Explorer, it instantly
shows a resource-level view of your costs.

AWS pricing can be crazy complicated.

Anyone who has looked at AWS pricing or tried to forecast AWS costs knows it can be a nightmare. Blue Matador made Cloud CORE to help engineers understand cloud costs at a more granular level.

How does it work?

First off, it is completely free. There are no hosting costs, subscriptions—nada.

You connect your AWS accounts, your browser will call the APIs in the background, and then you can explore your resource usage and costs.

Is this AWS pricing tool secure?

Blue Matador doesn't store or even have access to any of your data. Your AWS credentials are stored in your browser (local storage and cookies) using an encryption key that only you know.

You can review it yourself at Github.

Is this AWS cost calculator accurate?

The short answer is yes. The tool makes read-only API calls in real-time for your AWS accounts. You'll get an instant snapshot of all your AWS costs and an accurate projection if you were to continue usage at the same rate. You can select which time period is used for the calculations. It uses up-to-date costs from publicly available AWS Calculator endpoints.

Some recommended use cases for using Cloud Core.

New AWS User

If, as a newer user of AWS, you are still feeling your way through their pricing, don’t worry—even the most experienced people find it complicated. You’ve fiddled with the AWS pricing calculator tool, but it is near-impossible to predict what resources you’ll need in the future (or even now), so who knows if it is even accurate for your use case. Our Cloud CORE tool can be a quick resource to see exactly where your spend is at.

AWS Environment Changes

Your team just pushed some changes to your AWS account and you’d like to see how it is impacting your AWS cost before your bill arrives. Hop onto Cloud CORE and see real-time changes to your AWS charges. For best results, compare before and after you pushed the changes.

AWS Bill Surprise

You just got your monthly AWS bill, and it’s higher than you expected. In the bill, one of the services, like Lambda, was higher, but you don’t know which function, or even which region, caused the spike. Neither the bill nor AWS Cost Explorer go into resource-level details to see what is costing so much money. Cloud CORE instantly provides a resource-level view of your costs in a matter of minutes so you can see and fix your biggest offenders.
