CLUSTER PLAYBACK-SERVER-SYNCHRONIZES · 7 ENTRIES · EARLIEST ENTRY 2025-12-03

Peer-to-peer synchronized video playback

These products synchronize video playback across viewers without uploading files, using peer-to-peer connections, WebSocket event relay, or torrent-based delivery. The cluster's dated history before the index start consists of only 3 entries, too few to read a shape from, so it either predates the index or its members are largely undated. On traction, Viewpoint leads with 1 star, followed by WatchSync and FreeTube with 0 stars each.

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

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
