CLUSTER ALLOWS-KNOWLEDGE-QUIZ · 8 ENTRIES · EARLIEST ENTRY unknown

Web-based quiz apps

This cluster consists of web-based quiz applications that let users take quizzes on various topics, often with multiple-choice or form-based questions. The dated history is too thin to read a shape from—only one dated entry exists, and seven members have no source date. Traction leaders include Quiz-react_app, Techmanager Quizz, and Quiz, each with 0 stars.

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 8 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.
