copyparty

copyparty is an open-source, self-hosted file server that enables resumable uploads and downloads via web browsers. It allows users to turn almost any device into a storage node for sharing files and managing data across a network. The software is deployed as a server application requiring only Python to run, making it compatible with a wide variety of hardware environments from small home servers to larger machines.

Users interact with the server through a web-based file manager or via various network protocols. It supports a wide range of use cases, from simple file transfers and NAS frontends to hosting media libraries and e-book feeds. The server can be configured using command line arguments or configuration files, and it can be made accessible over the internet or restricted to a local area network using Zeroconf for service announcement.

Authentication can be handled via passwords, IP range restrictions, or external identity providers using OAuth. For mobile users, the software provides a dedicated Android app and supports iOS shortcuts to facilitate quick uploads from mobile devices.

copyparty serves as a portable utility for users needing a flexible file server with broad protocol support and a functional web interface.
