aria2 is a lightweight multi-protocol & multi-source, cross platform download utility operated in command-line. It supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink.

UI based on AriaNG ( )

aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, SFTP, BitTorrent, and Metalink. aria2 can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth. It supports downloading a file from HTTP(S)/FTP/SFTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP/SFTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.


Here is a list of features:

Command-line interface
Download files through HTTP(S)/FTP/SFTP/BitTorrent
Segmented downloading
Metalink version 4 (RFC 5854) support(HTTP/FTP/SFTP/BitTorrent)

JSON-RPC (over HTTP and WebSocket)/XML-RPC interface
Run as a daemon process
Selective download in multi-file torrent/Metalink

Configuration file support
Download URIs found in a text file or stdin and the destination directory and output file name can be specified optionally
Parameterized URI support
IPv6 support with Happy Eyeballs
Disk cache to reduce disk activity



listen on RPC Websocket 6800 by default
tokens set in /opt/AriaII/aria2.conf ( 7iQzqgg6Soe5MqpWGaLODhAbNcFwkFEaQYCQhCAtDrIZ by default )
