realPulse Index
realEach family contributes its observed strength × weight to the 0–100 Pulse. Missing families contribute nothing and are never renormalized, so an unobserved product reads lower — Pulse measures observed activity, not potential.

generated from the observed metrics above · no external narrativeNibbler's listed site resolved live when we last probed it on Jul 15, 2026, so we mark it verified alive. Its Pulse Index is 48.5 of 100, built from 2 of 4 observed signal families. Observed footprint: 4 functional tags. It sits on the competitive-alternatives graph with 1 linked rival, so the comparable set below leans on curated edges.

Confidence reflects source and category coherence: curated = an editorially linked alternative; similar = strong functional tag-overlap in the same category; tag-overlap = shared tags only and may be noisy. Pulse is the observed-activity index real; a dash means the comparable has no observed signal families.
