qsync

A fast and lightweight tool for local file synchronization—ideal when you do not need encryption. Qsync is inspired by rsync and leverages the performance of QUIC for efficient data transfer.

Features

• Delta sync
• Sync files, directories and symlinks
• Symlinks are synced as-is (target path validity is not verified)
• Optionally preserve timestamps and permissions
• Naive sync mode: only transfers files if size or modified time differs
• Powered by QUIC
• Certificate verification is disabled (therefore intended for local use only)
