CLUSTER CHAT-FILE-MESSAGING · 33 ENTRIES · EARLIEST ENTRY 2026-04-26

Self-hosted team chat apps

This cluster consists of self-hosted team chat applications offering messaging, file sharing, and often voice/video calls. The dated entries before the index start appear sporadically from 2016 to 2026, with a small grouping in 2023 and again in early 2026. Traction is led by once-campfire-rust with 87 stars, far ahead of lets-chat (6) and sideporch (2).

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.
