CLUSTER CHESS-ANALYSIS-DATABASE · 6 ENTRIES · EARLIEST ENTRY 2024-09-06

Chess database and analysis apps

This cluster comprises six chess database applications that focus on browsing, editing, annotating, and analyzing PGN files, with most also offering engine integration (e.g., Stockfish) and some supporting online play or tournament organization. The dated history before the index start is too thin to read a shape from—only four dated entries exist, predating the index or with undated members. On traction, the leading members (studio, scidCommunity, ScidvsPC) all show zero stars, indicating no clear traction leader among the group.

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 6 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.
