FrostWire is a free, multiplatform BitTorrent client, supporting the exchange of data shared by users from all over the world. The application also enables communication via a built-in chat. The program offers features such as bookmark multifinding, automatic determination of the fastest download source, proxy setting, resuming transfers, setting transfer limits, banning users, iTunes integration, and much more.

FrostWire was written in Java so it is also available for other operating systems. In the latest version, the internal search engine offers faster results with less spam. For easy data sharing, people sending files or entire folders can now generate an HTTP link.

FrostWire can recognize Creative Commons licenses in MP3 and OGG files and run music directly in the program without the need for external players.
