aria2 is a lightweight, cross-platform command-line download utility supporting HTTP/HTTPS, FTP, SFTP, BitTorrent, and Metalink with multi-source, multi-connection downloading. It can be controlled remotely via built-in JSON-RPC (HTTP/WebSocket) and XML-RPC interfaces.

Use cases

  • download files from http and ftp at maximum speed
  • segmented multi-connection downloading of large iso files
  • download torrents and magnet links from the command line
  • fetch a file from multiple mirrors simultaneously
  • run a headless download daemon controlled via rpc
  • validate downloads with metalink chunk checksums

When to choose

  • you need fast, scriptable downloads from many protocols in one tool
  • you want a lightweight headless downloader with remote RPC control
  • you need BitTorrent and HTTP/FTP downloading combined in one process

When to avoid

  • you prefer a graphical download manager or torrent client
  • you only need simple one-off downloads where curl or wget suffice
