Callink
Team messaging with channels, threads, fast file transfer and instant calls, end-to-end encrypted.
Flutter
DDD
WebSocket
End-to-end encryption
Callink pulls a team's messages, work items and tools into one place. Private and public channels, message threads, rapid file transfer, and voice and video calls that start instantly.
Security is the point rather than a feature line: conversations are end-to-end encrypted, so only the intended recipients can read them. The transport runs on WebSocket and the codebase is organised with DDD.
