What is copyparty?

copyparty is an open‑source, web‑based file server that lets you share directories, sync data, and collaborate without relying on third‑party cloud services. It runs on Windows, macOS, Linux and any system with a modern browser, offering a lightweight yet powerful alternative to traditional file‑hosting platforms. Designed for developers and power users, copyparty provides fine‑grained permission controls, API access, and extensibility through plugins, making it suitable for everything from ad‑hoc file drops to automated build artifact distribution.
