CLUSTER END-CHAT-HOSTED · 36 ENTRIES · EARLIEST ENTRY 2023-07-09

Self-hosted encrypted messengers

This cluster consists of self-hosted, end-to-end encrypted messaging and chat applications that emphasize privacy, data sovereignty, and federated or relay-based architectures. Entries appear intermittently from December 2021 through May 2026, with the largest monthly count being two in May 2026. The top traction signals (Haven, arveil, xsukax-NTFY-Encrypted-Chat) all show zero stars, indicating minimal public engagement.

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 16 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
