Uptime monitoring and status pages
This cluster covers open-source and self-hosted uptime monitoring tools that check websites, APIs, and services, alert on outages, and often publish status pages. Dated entries before the index began appear sporadically from 2016-07 through 2025, then concentrate in 2026, with the largest monthly counts in May, June, and July 2026. Traction leaders by activity signal are WebMetricsX (7 stars), pulse (12 stars), and middle-monitor (3 stars).
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
