qbeam

Move a file from a locked-down machine to your phone over animated QR codes. No network, no USB, no admin rights, and nothing to install on the receiving side. Transfers are verified with SHA-256.

uvx qbeam send app.log        # or: pipx install qbeam
uvx qbeam send ./project      # a folder goes as one .tar.xz; .gitignore respected

1. qbeam send <file> writes a self-contained <file>.sender.html and opens it in your browser (works offline). Press Fullscreen for the best speed.
2. On the phone, open the qbeam receiver page (qbeam receive prints its path; copy it to the phone once, it works offline) in Chrome or Safari and point the camera at the codes. The file saves once it's complete and its SHA-256 matches.

Options: --speed safe|fast|max (default fast; max needs a 60 fps phone camera), --encrypt (prints a passphrase to type on the phone; never shown on the QR screen), --name and - for stdin, --no-open, --tty (draw the codes in the terminal; automatic over SSH and on Linux without a display; slower than the browser page).

Nothing installed at all? Each GitHub release has a single-file qbeam-<version>.pyz: python3 qbeam-<version>.pyz send app.log.

Encryption needs the optional package: pip install "qbeam[crypto]" (or uvx --from "qbeam[crypto]" qbeam send ... --encrypt).

Status: early alpha (0.0.x). Terminal mode, higher speed and native apps are on the way: https://github.com/qbeam/qbeam
