MIT licensed.</p> <p><strong>Download:</strong> <a href="https://github.com/interfluve-wav/croc-gui/releases/latest" rel="noopener noreferrer">GitHub Releases</a></p> <h2> Why I built this </h2> <p>I send files with <strong>croc</strong> 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.</p> <p>Croc GUI is the Send/Receive desktop app I wanted: same croc binary, clearer UX.</p> <h2> What it does </h2> <ul> <li> <strong>Send</strong> — drag files/folders, get a code phrase + QR link</li> <li> <strong>Receive</strong> — paste a code, pick a download folder</li> <li> <strong>Share</strong> — copy phrase, getcroc.com URL, or full <code>croc …</code> command</li> <li> <strong>Local-only</strong> — <code>croc --local</code> for LAN peers</li> <li> <strong>Zip</strong> — pack on send, unpack helper on receive</li> <li> <strong>Options</strong> — relay, port, proxy, overwrite, auto-confirm</li> </ul> <h2> What it doesn't do </h2> <ul> <li>Reimplement croc's crypto or protocol</li> <li>Upload anything to a GUI-specific cloud</li> <li>Claim to be an official schollz project</li> </ul> <p>Transfer engine: <strong><a href="https://github.com/schollz/croc" rel="noopener noreferrer">schollz/croc</a></strong>.
