CLUSTER END-ENCRYPTED-MESSAGING-2 · 9 ENTRIES · EARLIEST ENTRY 2026-06-04

Tor-based anonymous messaging apps

This cluster consists of privacy-focused messaging applications that use Tor to provide end-to-end encrypted chats without requiring phone numbers or emails, aiming to eliminate metadata trails. The cluster's dated history is too thin to read a shape from—only three dated entries exist before the index start, so it predates the index or its members are undated. Among traction leaders, hollow-chat leads with 3 stars, while ObsidianOS and Kryfo have 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.
