Croc GUI: Encrypted Peer-to-Peer File Transfer Without the Terminal (Cross-Platform)

TL;DR

Croc GUI is a free desktop app for schollz/croc — encrypted peer-to-peer file transfer with drag-and-drop, QR codes (via getcroc.com), and LAN mode. macOS, Windows, Linux. MIT licensed.

Download: GitHub Releases

Why I built this

I send files with croc constantly. End-to-end encrypted, cross-platform, no vendor cloud. The CLI is perfect — until you’re helping someone who doesn’t have a terminal open.

Croc GUI is the Send/Receive desktop app I wanted: same croc binary, clearer UX.

What it does

• Send — drag files/folders, get a code phrase + QR link
• Receive — paste a code, pick a download folder
• Share — copy phrase, getcroc.com URL, or full croc … command
• Local-only — croc --local for LAN peers
• Zip — pack on send, unpack helper on receive
• Options — relay, port, proxy, overwrite, auto-confirm

What it doesn’t do

• Reimplement croc’s crypto or protocol
• Upload anything to a GUI-specific cloud
• Claim to be an official schollz project

Transfer engine: schollz/croc. Please sponsor schollz.

Stack
