Matrix protocol chat clients

This cluster consists of 15 chat client applications built on the Matrix protocol, offering encrypted messaging, rooms, direct and group chats, and in some cases voice/video calls, spaces, threads, and file sharing. Dated entries appear sporadically from January 2022 to July 2026, with a noticeable gap between July 2023 and February 2025 and a denser series of entries from April to July 2026. The traction leaders, tesseract-matrix, Sable, and Cinny, each show 0 stars on activity signal, indicating an early-stage, competitive field.

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.
