Codebase Q&A search tools

This cluster consists of web applications that index code repositories and let developers ask natural-language questions about the code, with some offering semantic search, dependency visualization, and source references. The cluster's dated history is too thin to read a shape from – it predates the index or its members are undated. On traction, cgdweb-be300e6e, codebase-rag-assistant, and -Codebase-AI-Engineer lead with zero stars each.

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 14 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.
