Open Source Swift Download Managers

Aria2D is an open-source download manager for macOS that provides a native graphical interface for the aria2 command-line utility. It simplifies managing downloads without requiring users to interact directly with terminal commands. The application supports HTTP, HTTPS, FTP, SFTP, BitTorrent, and Metalink transfers through the underlying aria2 engine. Users can access the complete set of aria2 download options through its graphical controls. Automatic aria2c startup eliminates the need to launch the download service manually. Multi-server support allows connections to different aria2 instances from the same application. Native macOS Shortcuts integration provides additional workflow automation. Aria2D also offers download notifications and a dark mode interface. Developed with Swift, it combines aria2's downloading capabilities with macOS desktop integration.
