10 of 33 agent platforms have a confirmed yes for “Self-hosted”. 11 are qualified or tier-scoped, 11 are confirmed no, and 1 remain not established. Only confirmed yes answers appear in this set; an unknown is never treated as a negative.

This is not an arbitrary slice of agent platforms. Among the ones with a confirmed yes for “Self-hosted”, only 1 of 10 answer yes on certifications, against 18 of 23 across the rest; and 6 of 10 also answer yes on open source, against 1 of 23 across the rest of the category. Every figure is counted from the stored, sourced datasheet answers linked on each row.

## Methodology

Projected from the live listing datasheets using the tenant’s “Can you run it on your own infrastructure?” 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 34 other datasheet axes, Holm-corrected. Entries retain the directory’s paid-tier ordering, visibly labelled on every promoted card.
