generated from the observed metrics above · no external narrativevelocity.js's listed URL redirected off its original domain (to http://velocityjs.org/) when we last probed it on Aug 24, 2026 — we mark it redirected, not dead. Its Pulse Index is 20.3 of 100, built from 2 of 4 observed signal families. Observed footprint: 5 functional tags. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags.

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.
