yeet your file across the interweb

yeet is a fast, zero-setup, peer-to-peer (P2P) file transfer tool powered by modern WebRTC. yeet also works without an internet connection if both the receiver and sender are on the same local area network.

Installation

Make sure you have Go installed, then run:

go install github.com/rawtxt/yeet@latest

Or build and install locally from source:

git clone https://github.com/rawtxt/yeet.git
cd yeet
go install

Basic Usage

Receive

Run yeet without arguments to wait for a payload. It registers your session and gives you a 3-word phrase code:

yeet

Output:

Your Session ID: alert-aware-bacon
Local IP: 192.168.1.50
Waiting for a sender to connect...

Send

Yeet files directly to your receiver by specifying filenames:

yeet cat.jpg book.pdf

Output:

Enter Session ID: alert-aware-bacon
🔗 Connected to signalling server! Handshaking with receiver...

Direct IP / LAN Transfer

To receive files directly without registering with any external matchmaker server:

yeet -no-matchmaker

Connect directly to a receiver's IP address on the local network (bypassing the public matchmaker):

yeet -receiver-ip 192.168.1.50 cat.jpg

Self-Hosted Matchmaker Server

You can run your own combined matchmaking server (signalling HTTP server + STUN UDP server):

yeet -run-matchmaker -addr :8080 -stun-addr :3478

To point your sender or receiver to a custom matchmaker server:

# Receive using custom matchmaker
yeet -matchmaker http://localhost:8080

# Send using custom matchmaker
yeet -matchmaker http://localhost:8080 file.zip
