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. -

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. -

frp
A Fast Reverse Proxy
frp stands for exactly what it is: a fast reverse proxy. It helps you expose a local server behind a NAT or firewall to the Internet. It is currently under development, but already supports TCP and UDP, as well as HTTP and HTTPS protocols where requests can be forwarded to internal services by domain name. It also has a P2P connect mode and many other nifty features. These include configuration files, environment variables, a dashboard that shows you frp's status and proxies' statistics information, an Admin UI that helps you check and manage frpc's configuration, and many others. -

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. -

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. -

Shadowsocks Rust
A Rust port of shadowsocks
Shadowsocks Rust is an open-source, high-performance implementation of the Shadowsocks secure proxy protocol written in Rust, designed to provide fast, encrypted SOCKS5-based tunneling to help users bypass network censorship and protect privacy. Shadowsocks itself is widely used to route internet traffic through an encrypted proxy, allowing secure access to blocked or restricted content while mitigating simple traffic-inspection techniques. By leveraging Rust, this implementation emphasizes memory safety, concurrency, and efficiency, making it suitable for both client and server use on devices ranging from small embedded systems to large servers. The repository includes multiple binaries such as sslocal for local SOCKS5 proxy clients and ssserver for remote proxy servers, giving developers flexible components to build customized proxy setups. It also supports modern asynchronous networking patterns, optional DNS handling, transparent proxy modes, tunneling, and advanced cipher methods. -

V2Fly
A platform for building proxies to bypass network restrictions
V2Fly Project V is a set of network tools that helps you to build your own computer network. It secures your network connections and thus protects your privacy. Help you build an exclusive basic communication network. A V2Ray process can concurrently support multiple inbound and outbound protocols, and each protocol can work independently. Inbound traffic can be sent from different outlets according to the configuration. Easily implement distribution by region or domain name to achieve optimal network performance. V2Ray can open multiple protocol support at the same time, including Socks, HTTP, Shadowsoks and VMess. The transmission carrier can be set separately for each protocol, such as TCP, mKCP and WebSocket. Nodes of V2Ray can be disguised as a normal website (HTTPS) to confuse its traffic with normal web traffic to avoid third-party interference. Universal reverse proxy support can achieve intranet penetration. -

Antigravity-Proxy
Transparent proxy injector for Antigravity
Antigravity Proxy is a Windows proxy injection tool made specifically for the Antigravity editor. It is designed to route Antigravity-related traffic through a SOCKS5 or HTTP proxy without requiring Clash TUN mode. The project focuses on selective proxying instead of taking over all system traffic. This makes it useful for users who need Antigravity to work through a proxy while keeping the rest of their Windows network behavior unchanged. Its approach is transparent to the target application, so Antigravity does not need to be configured as if it were proxy-aware. The tool is especially relevant for users in restricted network environments who want a more controlled, app-specific proxy workflow. -

Pirate Bay Proxy List 2026
Working The Pirate Bay proxy list 2026
Pirate Bay Proxy List 2026 is a public repository that maintains a frequently updated list of proxy and mirror sites for The Pirate Bay. It is designed as a simple directory that highlights working links, availability, and access options rather than providing a complex software system. The project emphasizes regular updates and verification, making freshness its main practical feature. It is mostly HTML-based and oriented toward easy browsing through a published GitHub Pages-style site. Because the links relate to torrent access, users must evaluate legality, safety, and copyright compliance in their own location before using any listed resource. From a software perspective, the repository is best described as a curated, static web directory. -
