How this page is made
Alternatives come from Onyx's own category, AI search engines. Prices come from each vendor's pricing page and are compared at the same volume where both can be computed, and by starting price where neither can. "States that Onyx doesn't" lists what we found on the other vendor's site and didn't find on Onyx's, which doesn't prove Onyx lacks it. How prices are read.
