Jackett works as a proxy server, it translates queries from apps (Sonarr, Radarr, SickRage, CouchPotato, Mylar3, Lidarr, DuckieTV, qBittorrent, Nefarious, etc.) into tracker-site-specific HTTP queries, parses the HTML or JSON response, and then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping & translation logic, removing the burden from other apps. Trackers marked with (invite needed) have no active maintainer and may be missing features or be broken. If your client supports multiple feeds it's recommended to add each indexer directly instead of using all indexers. Using the all indexer has no advantages (besides reduced management overhead). We recommend you install Jackett as a Windows service using the supplied installer. You may also download the zipped version if you would like to configure everything manually.

Cloud torrent is a a self-hosted remote torrent client, written in Go (golang). You start torrents remotely, which are downloaded as sets of files on the local disk of the server, which are then retrievable or streamable via HTTP. Go is required to install from source. The provided set of core features requires large structural changes and therefore requires a complete rewrite for best results. This rewrite is in progress in the 0.9 branch though it will take quite some time. It will be capable of transfering files from and source file-system to any destination file-system. A torrent can be viewed a folder with files, just like your local disk, and Dropbox. As long as it has a concept of files and folders, it could potentially be a cloud-torrent file-system backend. During a file tranfer, one could apply different transforms against the byte stream for various effect.

WebTorrent is a streaming torrent client for node.js and the browser. YEP, THAT'S RIGHT. THE BROWSER. It's written completely in JavaScript – the language of the web – so the same code works in both runtimes. In node.js, this module is a simple torrent client, using TCP and UDP to talk to other torrent clients. In the browser, WebTorrent uses WebRTC (data channels) for peer-to-peer transport. It can be used without browser plugins, extensions, or installations. It's Just JavaScript™. Note: WebTorrent does not support UDP/TCP peers in browser. To make BitTorrent work over WebRTC (which is the only P2P transport that works on the web) we made some protocol changes. Therefore, a browser-based WebTorrent client or "web peer" can only connect to other clients that support WebTorrent/WebRTC.
