A web application that transfers files between devices using animated QR codes displayed on one screen and captured by another device's camera, requiring no network connection. It uses fountain coding for error resilience, supports files up to 64 MB, verifies integrity with SHA-256, and works offline as an installable PWA.

Use cases

• transfer a file to a phone with no internet connection
• move photos between devices without pairing or accounts
• send files across an air gap using only screen and camera
• share a file with someone by displaying animated QR codes
• receive a file by pointing a camera at a screen
• export a QR animation so any camera can receive the file later
• transfer data between devices with no shared network

When to choose

• you need to move a file between devices with no network path between them
• you want a zero-install, browser-based transfer that works offline
• you need air-gapped transfer without pairing, accounts, or cloud storage

When to avoid

• you need confidentiality - the stream is unencrypted and readable by any camera
• you need to transfer files larger than 64 MB
• you need high-speed bulk transfer over long distances
