Questions
Is there a free alternative to Appen?
Yes. 5 data labeling software have a free plan, including Label Studio (HumanSignal), CVAT, Roboflow, Supervisely, Labellerr.
How this page is made
Alternatives come from Appen's own category, Data labeling software. 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 Appen doesn't" lists what we found on the other vendor's site and didn't find on Appen's, which doesn't prove Appen lacks it. How prices are read.
