Side by side

What it does

A single-file Python file server with resumable uploads, deduplication, thumbnails, media indexing and access over HTTP, WebDAV, SFTP, FTP, TFTP and SMB.

A free cross-platform app that sends files and text between nearby devices over the local network using HTTPS, with no internet or account needed.

Watch out

Mostly one developer's work, and its many protocols and options need careful permission configuration before exposing it to the internet.

Devices must be on the same network, and some corporate or guest Wi-Fi blocks the discovery it relies on.
