Cloudflare Tunnel Client
Cloudflare Tunnel Client
Contains the command-line client for Cloudflare Tunnel, a tunneling daemon that proxies traffic from the Cloudflare network to your origins. This daemon sits between Cloudflare network and your origin (e.g. a webserver). Cloudflare attracts client requests and sends them to you via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible. Extensive documentation can be found in the Cloudflare Tunnel section of the Cloudflare Docs. All usages related with proxying to your origins are available under cloudflared tunnel help. You can also use cloudflared to access Tunnel origins (that are protected with cloudflared tunnel) for TCP traffic at Layer 4 (i.e., not HTTP/web socket), which is relevant for use cases such as SSH, RDP, etc. Such usages are available under cloudflared access help. -

Jackett
API Support for your favorite torrent trackers
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. -

UFTP
Encrypted UDP based FTP with multicast
UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers. -

1337x Proxy List
1337x Proxy List for 2026
1337x Proxy List is an open-source repository that curates a collection of proxy and mirror sites designed to provide access to the 1337x torrent platform when it is blocked or restricted in certain regions. The project aggregates and maintains a list of working proxy URLs that allow users to bypass ISP or government restrictions by routing traffic through alternative domains. These proxy sites replicate the original 1337x interface and functionality, enabling users to browse, search, and download torrent files as if they were accessing the main site directly. The repository is updated periodically to ensure that listed proxies remain functional, as many of them may go offline or become blocked over time. It also includes explanations of why torrent sites are often restricted, typically due to copyright enforcement and bandwidth concerns. -

FlareSolverr
Proxy server to bypass Cloudflare protection
FlareSolverr is a proxy server to bypass Cloudflare and DDoS-GUARD protection. FlareSolverr starts a proxy server, and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Firefox). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user, and those cookies can be used to bypass Cloudflare using other HTTP clients. Web browsers consume a lot of memory. If you are running FlareSolverr on a machine with few RAM, do not make many requests at once. With each request, a new browser is launched. It is also possible to use a permanent session. However, if you use sessions, you should make sure to close them as soon as you are done using them. It is recommended to install using a Docker container because the project depends on an external browser that is already included. -
