## Methodology

Projected from the live listing datasheets using the tenant’s “Can you pull the data into your own stack?” axis. Membership requires a sourced yes; partial and unknown answers are reported above but excluded from the ranking. Differences from the rest of the category are Fisher exact tests over 31 other datasheet axes, Holm-corrected. Entries retain the directory’s paid-tier ordering, visibly labelled on every promoted card.
