quic-send

quic-send is a peer-to-peer file transfer tool that uses the QUIC protocol to transfer data over a direct connection (no relay involved).

Note

Because quic-send uses NAT-traversal, a direct connection might not be possible on every network.

Features

• P2P Data transfer: All files are sent over a direct connection, the data is never relayed through another server. The only other parties involved is a STUN server (Google STUN) and an optional roundezvous server (included in this repo).
• Encryption: quic-send uses the encryption provided by the quinn crate (which uses rustls and ring under the hood).
• Resumable transfers: If the connection is lost, the transfer can be resumed from where it left off.
• Transfer files & Folders
• No port forwarding required: quic-send makes use of UDP hole punching to establish a connection between the two peers, without requiring open ports.

Installation

The cli version can be downloaded from crates.io:

cargo install qs-cli

Downloads to the gui version (as well as the cli version) can be found on the releases page

Usage

Sending files

$ qs send <file/folder>
code: 123456
on the other peer, run the following command:

qs receive 123456

Receiving files

$ qs receive 123456

Comparison with other file transfer tools

Feature	quic-send	Magic Wormhole	croc
Encryption	✅	✅	✅
Direct (P2P) transfer	✅	(✅)*	❌
Resumable transfers	✅	❌	✅
Transfer files & Folders	✅	✅	✅
(fallback) Relay server	❌	✅	✅

• While it is possible in Magic Wormhole, establishing a direct connection is very unlikely (as the connection tries to establish a direct TCP connection), quick send uses UDP hole punching instead which is way more reliable and works for most networks.
