aria2 is a multi-protocol & multi-source, cross platform download utility. The supported protocols are HTTP(S), FTP, BitTorrent, Metalink. It can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth.

trackerslist is a repository that provides continuously updated lists of public BitTorrent trackers, designed to improve torrent download performance and peer discovery. The project is maintained by an automated system that regularly checks tracker availability, removes duplicates, and ranks them based on reliability and latency. It offers multiple formats of tracker lists, including HTTP, HTTPS, WebSocket, and IP-based versions, making it compatible with a wide range of BitTorrent clients. The lists can be integrated into torrent files or magnet links to enhance connectivity and download speeds. Additionally, the project includes specialized lists for alternative networks such as I2P and Yggdrasil, expanding its usability in privacy-focused environments. By maintaining clean, validated, and optimized tracker collections, trackerslist acts as a foundational resource for improving BitTorrent efficiency.

peerflix is a Node.js-based streaming torrent client that lets you stream video or audio files directly from a torrent (magnet link or .torrent file), without needing to wait for the entire download to finish. It spins up a small HTTP server that serves the torrent’s content as it’s downloaded; for example, if you point a media player (like VLC or MPV) to the provided URL, it will start playing almost immediately. Peerflix automatically selects the largest file in a multi-file torrent by default (or can list all files for manual selection), and supports passing arbitrary flags to the media player — letting you stream with subtitles, full-screen mode, or other player-specific options. Because it's built on the torrent peer network, it downloads pieces on demand as playback proceeds, which can be more efficient if you only want to watch a single file. Peerflix also exposes programmatic API usage using underlying low-level torrent-streaming logic.

Enhanced CTorrent is a BitTorrent client for unix-like environments. High performance with minimal system resources and dependencies is a priority.

Torrent Search is a cross-platform application, allowing to search for torrent files on different websites. Supported websites are integrated through plugins, which allows to easily extend the number of websites supported.

TrackersListCollection is a daily-updated collection of BitTorrent tracker server lists, curated and filtered from across the internet to build a “best of” list and a full list for usage in torrent clients, automation, or performance tuning. The project scans public trackers, tests their responsiveness or status, categorises them (e.g., all trackers vs best trackers), and makes plain-text files available (like best.txt, all.txt) that can be included in download clients or scripts. Because trackers can go offline or degrade over time, the daily refresh schedule is crucial for maintaining a high-quality list. The repo also includes metadata and mirrors to handle international usage and multiple download sources. For people who use torrent infrastructure, ensure peers connect reliably, or want to automate external tracker lists for aria2 or other clients, this is a practical and well-maintained source.

This project has been moved to https://launchpad.net/baretorrent. There will be no more new releases on sourceforge. The web page is at http://baretorrent.org. Old description: This is a portable BitTorrent client with basic features along with support for extensions. The most recent release (18-jan-2013) is 0.4 for Windows, Debian 6.0.6, Ubuntu 12.04 and OSX 10.6.8. Only one extension is available so far: a simple server that is compatible with how the uTorrent WebUI adds torrents. Therefore, Firefox extensions such as BitTorrent WebUI++ work fine for adding torrents. See http://baretorrent.org/ext.html.
