Aria2 Download Manager Overview
aria2 is a free, open-source, lightweight command-line download utility for Windows, macOS, and Linux that supports multiple protocols in a single tool: HTTP/HTTPS, FTP, SFTP, BitTorrent, and Metalink. It is designed for speed and efficiency, able to download a file from multiple sources and connections at once to maximize bandwidth, and it runs as a background process that can be controlled remotely through a JSON-RPC or XML-RPC interface — which is why many graphical front-ends and download tools are built on top of it. Its small footprint and scriptability make it popular for servers, automation, and power users. Its full installer holds the complete application, so it sets up on a machine with no internet connection. It supports download resumption, checksum verification, and proxy configuration, and runs efficiently even on low-powered devices.
