−1 stale_verification We cannot confirm this offer: 3 consecutive re-check attempts have failed (most recently 2026-09-24 — The pricing page does not explicitly mention a free tier with the stated limits (5 hosts, 1-day retention). It broadly lists Infrastructure Monitoring as a product but doesn't detail free tier specifics within the provided text.), never confirmed since it was indexed. This is our inability to verify, not a change by the vendor.
