CLUSTER WEB-EVENT-PARTICIPANTS · 37 ENTRIES · EARLIEST ENTRY 2025-03-10

Event and program registration apps

This cluster consists of web applications focused on registering participants for events, programs, and camps, with features for managing enrollments. The five dated entries appear sporadically from February 2025 to June 2026, including two in February 2026 and one in each of the other months. Traction leaders are dvow26, kickball-app, and zbc-rec.forms, each with an activity signal of zero stars, indicating low observed engagement.

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.
