CLUSTER END-DECENTRALIZED-ENCRYPTED · 97 ENTRIES · EARLIEST ENTRY 2015-12-21
Encrypted secure messaging apps
This cluster comprises end-to-end encrypted messaging apps emphasizing private chats, calls, and file sharing. Dated entries span from April 2010 to July 2026, appearing consistently with an increasing frequency in later years, though counts before the index start reflect discovery coverage over time. Traction leaders are chatsapp with 1 star, followed by Council – Encrypted Messaging and Secure-Chat with 0 stars each.
Entry timeline
ENTRY TIMELINE
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.
