Instapaper
Verified live by HTTP probe across 17 observations. Pulse momentum is positive over 30 days (+4.2). Observation is liveness-only: no tracked press, repository, or traffic rank — existence is confirmed, momentum is unobserved.

generated from the observed metrics above · no external narrativeInstapaper's listed site resolved live when we last probed it on Aug 24, 2026, so we mark it verified alive. Its Pulse Index is 44.2 of 100, built from 2 of 4 observed signal families. Observed footprint: 6 functional tags. It sits on the competitive-alternatives graph with 2 linked rivals, 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.
