Leech

Leech is a lightweight yet powerful download manager for those who download a lot of stuff.

It features everything you’d expect in a download manager—acceleration, bandwidth throttling, scheduling, rules, download history, and much more.

Despite its rich feature set, Leech doesn’t ask a lot of your Mac, and sits quietly in the background, just waiting for you to put it to work. Drag and drop URLs, or open them via a contextual menu in Safari, and then Leech starts working for you.

Why tie your download activities to your browser? Put to work for you, and we’ll free your browser from its download duties.

Note: may not work properly with file hosting services that use custom authentication methods.
