PicoTorrent is a free, open source, and easy-to-use BitTorrent client for Windows and Linux. It is a lightweight app that uses the libtorrent library, which is the same library used by popular BitTorrent clients such as qBittorrent and Deluge. It supports all the common BitTorrent features, including magnet links, selective downloading, DHT, PEX, encryption, and more. It also has an integrated search engine, allowing users to search for torrents directly within the app. It also includes handy features such as pause/resume downloads, scheduling, bandwidth control, UPnP/NAT-PMP port forwarding, RSS, and much more.
Warning Host IP can be used as exit nodes: it means that if some other user downloads something illegal, he might be prosecuted because his IP appears! Even on the official Tribler website, a Disclaimer says: "Don't put yourself at risk. Our anonymity is not yet mature. Tribler does not protect you against spooks and government agencies."
