webmtp — MTP file browser

Name	Size	Modified

Empty folder.

Runs entirely in your browser — files move between the device and this page over WebUSB; nothing is uploaded anywhere.

Needs Chrome or Edge (Firefox/Safari don't ship WebUSB), and the OS matters: macOS works out of the box (quit Android File Transfer–style helpers first); Linux works after unmounting the device from the file manager (and udev permissions); Windows effectively doesn't — its built-in MTP driver owns the device and the browser can't claim it. Details in the README.
