How this service works
Cross-region AWS price comparison. Find the cheapest region for any service in one API call.
Output
Returns a JSON object with the cheapest region and its price, a full list of all regions compared with their prices, the most expensive region, total number of regions compared, and the percentage savings versus the most expensive region.
Example use cases
Find cheapest region for RDS
“I'm planning to deploy a new RDS database and want to keep costs down. Can you check all AWS regions and tell me which one is cheapest for RDS, and how much I'd save compared to the most expensive region?”
Compare S3 storage costs globally
“We're storing a lot of data in S3 and I want to make sure we're in the most cost-effective region. Can you compare S3 pricing across all AWS regions and show me where we'd get the best deal?”
Optimize Lambda spending by region
“Our Lambda functions are getting expensive and I want to know if we're in the right region. Can you pull pricing for Lambda across every AWS region and tell me which one is cheapest and what percentage we could save by switching?”
