UTorrent web is a software that allows users to download and stream torrents directly in their default web browser.
In September 2018 BitTorrent Inc. announced that uTorrent Web is now beyond beta version. With the first full release, the company hopes to better meet the streaming requirements of today’s users.
For now uTorrent Web is only available for Windows, but it is planned to create the Mac version in near future. The application works in all major browsers, including Firefox, Chrome and Internet Explorer.
