Yes. 1 AI governance tools has a free plan, including Arize AI.
How this page is made
Alternatives come from Fiddler AI's own category, AI governance tools. 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 Fiddler AI doesn't" lists what we found on the other vendor's site and didn't find on Fiddler AI's, which doesn't prove Fiddler AI lacks it. How prices are read.
