GitHub contribution heatmaps

The cluster consists of tools that visualize GitHub contribution activity as calendar heatmaps, spanning web apps and terminal interfaces. With only two dated entries from before the index began, the cluster's dated history is too thin to infer a shape; it likely predates the index or its members are undated. Traction leaders all report zero stars, indicating minimal community adoption at discovery time.

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 5 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.
