macOS system monitoring apps

These products are macOS menu bar applications that display real-time system metrics such as CPU, memory, disk, and network usage, with some offering click-through details or historical data. The cluster's dated history is too thin to read a shape from, as no dated entries exist before the index start; it predates the index or its members are undated. ActivityMonitor leads with 35 stars, followed by CalmBar at 13 and launchboard at 6.

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

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.
