Some providers price by data transferred, some bundle products, and Galxy prices on-demand delivery by delivered video hour.
Start with the unit
A per-GB rate and a per-viewing-hour rate cannot be compared directly without assumptions about bitrate and traffic. Normalize both into a common scenario before deciding which appears cheaper.
Galxy's published rate
Galxy video delivery is $0.03 per delivered hour. Customers can start with as little as $25 in credits.
Model the whole workflow
Delivery is only one cost. Galxy publishes storage at $0.25 per stored hour and encoding at $2.50 per encoded hour, while Pro is an optional $75/month.
Next step
If you are evaluating a platform rather than learning the concept, compare the operational workflow and the cost model together.
