We are launching a pricing page in the next month as we are gearing up for launch :)
One example of recieving a 50% cost saving is from Amazon Machine Images (AMIs). We compared the cheapest official NGINX AMI available on the Amazon Marketplace[0] and then also ran an NGINX+Unikraft AMI. We ran the same workload using wrk[1] and then checked the bill at the end of the month, roughly $80 vs $40.
