Its Pulse Index is 24.3 of 100, built from 2 of 4 observed signal families. Observed footprint: 3 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. Overlap is the shared functional-tag ratio (Jaccard) for tag-matched rows. Pulse is the observed-activity index real and 30d Δ its signed month change; a dash means insufficient observed history, never zero.
