AWS Cost Calculator

Ever wonder what your AWS bill will look like before you hit deploy? I did, so I built this interactive tool to estimate EC2, S3, RDS, and Lambda costs in real time using live APIs. This originated from a real client need at Apex Analytix and was later reused at Vectorflow to support budget-aware deployments.
