Down Detector's site could not be verifiably probed when we last probed it on Aug 27, 2026, so its status is unverified — we do not guess. Its Pulse Index is 17.1 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.

not in source

No disclosed funding in our sources. Funding data covers only ~1% of the corpus (462 rounds across 79K products), so absence here is unknown, not zero— we don't estimate a number we can't source.
