That's the reason they are not listed :) They don't have a clear pricing like the other CDNs. They have internal limits and overages for bandwidth but its not public.
That's not true. We do not have overages. We don't charge for bandwidth. If you use a lot of bandwidth then we may contact you and see if paying for service makes more sense for you (for example, if you are running a business on our free plan then the level of support you get might not be what you need; or there may be missing features that would help you).
A close friend of mine also got multiple emails from sales telling that he is using too much bandwidth on the Pro plan and asking to upgrade to $2000/month+ or "else". But they were not able to define what would happen otherwise.
Now I guess its just a scare tactic?
Are you sure on the "we do not have overages"? Could I have 100TB of monthly traffic all served by your edge nodes (force cache everything + long expiry + files split into chunks) of legal content (firmware files for embedded devices) and not get kicked off?
