Catalog record last updated: 2026-09-20T12:22:45Z. This is not a verified transfer date.

Presence in the observed app sample

4 of 25381 apps scanned successfully within 30 days list this plugin in their latest captured configuration.

Confirmed listing- or maker-linked demo apps: 0 · Probable bundle matches: 0 · Unknown lineage: 4.

Excluding confirmed demos and probable matches leaves 4 observed configurations. This is a sensitivity count, not independent adoption, purchases, active use or a corrected Bubble install count.

Latest successful scan in this sample: 2026-09-23T01:39:05.283420Z. Successful rescans replace prior presence. Stale or missing scans are excluded; failed scans do not erase prior evidence. Historical links alone, including developer authorizations, do not count as observed presence.

Sample and classification methodology

Observed ownership changes

Up to 100 most recent changes. These establish a different listed owner, not a verified purchase.

No ownership changes recorded yet. History begins with successful observations; older transfers are not reconstructed.

Successful observations

Latest 100 observations, newest first. Times are UTC. Fingerprints cover the preserved public metadata fields.
