LeanMoth

LeanMoth finds the data-transfer waste hiding in your AWS bill. Drop a Cost & Usage CSV into the browser and get a free number for how much you're wasting per month — cross-AZ traffic, NAT Gateway processing, CloudFront egress, cross-region transfer, and more. Everything parses client-side. Your account IDs, resource names, and tags are never read from the file. The parsing code is public on GitHub, so the privacy claim is verifiable, not just stated. Unlike one-shot cost tools, LeanMoth remembers every report you run. Come back next month and it shows you which findings improved, which stayed flat, and what's new — so you know whether your fix actually worked. Free scan gives you the headline number. The full report costs 15% of the first month's savings, capped at $50. Find nothing, pay nothing.
