- The page lists groups up to 200 people, files up to 50 MB, and a Docker-installed organization node.
Field notes
The page separates delivery into an internet-connected relay, nearby-phone forwarding over Wi-Fi Direct or local Wi-Fi, and a browser-like WebSocket connection. For organizational use, it describes a self-hosted Docker node, groups capped at 200 members, and file transfers up to 50 MB; these are page-stated capabilities, not independently tested here. Download paths listed include an Android 10+ APK, a Windows installer, and a browser version.
