The title here mentions reducing costs by 90%, but on the homepage you list reducing cost by 50% (twice), reducing bandwidth by 99%, and offloading 90% of bandwidth. On the github page it lists reducing costs by 30%
From a first-read perspective those are vastly different numbers (30-99%), for what all sound like the same thing (reducing bandwidth by 99% sounds like it should reduce my costs by 99%).
Might want to be more specific (or pick a single number).
