CLUSTER AFTER-MESSAGES-AUTOMATICALLY · 6 ENTRIES · EARLIEST ENTRY 2013-11-21

Ephemeral encrypted messaging apps

This cluster consists of messaging apps focused on privacy and ephemerality, with end-to-end encryption, auto-deleting messages after short windows or after being read, and user-controlled chat erasure. Five dated entries before the index start are scattered from 2013-11 through 2026-07 with a long gap between 2013 and 2025, so the dated history is too thin to read a clear shape from. On traction, all three named leaders show zero-star activity signals, with blackchat listed first, followed by Ocean's Wave: Private Chat and Radio Bravo.

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.
