CLUSTER DECENTRALIZED-END-WITHOUT · 18 ENTRIES · EARLIEST ENTRY 2022-07-12

Decentralized encrypted messaging apps

This cluster comprises decentralized messaging applications that provide end-to-end encrypted communication without central servers, often allowing users to chat without signing up or sharing personal data. Entries appeared sporadically from February 2017 through July 2026, with two entries in both June and July 2026 being the highest monthly counts. MNDO leads traction with 3 activity 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.
