Every guide opens with an address bar. It runs the same engine as the paid report, on the free tier.

The full report.
$99, one time, never expires: every deliverable, free re-runs, 12 months of monitoring.
Every finding is queried live from its federal source (FEMA, USGS, EPA, USDA, Census) or a named commercial partner. A factor with no data drops out of the score. Never estimated.
