ShadowCat, a new open-source tool, allows users to transfer files between devices through QR codes generated in a web browser. The project gained traction on Hacker News with over 100 points and 40 comments.
ShadowCat simplifies peer-to-peer file sharing by encoding data into scannable QR codes, eliminating the need for cloud services or complex setup processes. Users can generate QR codes directly in their browser and transfer files by scanning with another device.
The tool works entirely within the browser environment, making it accessible without additional software installation. This approach offers a quick alternative to traditional file-sharing methods like email, messaging apps, or cloud storage services.
The project is hosted on GitHub under an open-source license, inviting community contributions and improvements. Its minimalist design and browser-based approach appeal to developers seeking lightweight solutions for temporary file transfers.
While QR code file transfer has limitations regarding file size and complexity, ShadowCat's implementation provides a practical option for sharing smaller files between nearby devices quickly.
