ngrok
Unified ingress for developers
ngrok is a globally distributed, secure reverse proxy and tunneling service that exposes applications running on local machines behind NATs or firewalls to the public internet. It simplifies remote debugging, webhooks integration, and secure ingress by wrapping reverse proxy, firewall traversal, API gateway, and load-balancing functionality into a single tool. ngrok is a globally distributed reverse proxy that secures, protects and accelerates your applications and network services, no matter where you run them. You can think of ngrok as the front door to your applications. ngrok combines your reverse proxy, firewall, API gateway, and global load balancing into one. ngrok can capture and analyze all traffic to your web service for later inspection and replay. -

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. -

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. -

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. -

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. -

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. -

SMTP Tunnel Proxy
A high-speed covert tunnel that disguises TCP traffic as SMTP email
SMTP Tunnel Proxy is a high-speed covert tunneling proxy that disguises regular TCP traffic as legitimate SMTP email communication to evade deep packet inspection (DPI) firewalls and censorship systems. It implements a SOCKS5 proxy interface on the client that wraps outbound traffic into an SMTP-like handshake (EHLO, STARTTLS, AUTH) and encrypted payload, making the session appear to DPI systems as a normal email exchange. The tool supports modern TLS encryption (STARTTLS) with HMAC-SHA256 authentication, per-user secrets, IP whitelisting, and multiplexed connections over a single tunnel. With a simple installer and systemd service setup, users can quickly deploy it on a Linux VPS as a tunneled access point, then connect from Windows, macOS, or Linux clients using auto-generated client packages. The project is useful for environments where standard VPNs or proxies are blocked, offering a combination of performance and stealth. -

Skipper
An HTTP router and reverse proxy for service composition
Skipper is an HTTP router and reverse proxy for service composition. It’s designed to handle large amounts of dynamically configured HTTP route definitions (>800000 routes) with detailed lookup conditions, and flexible augmentation of the request flow with filters. It can be used out of the box or extended with custom lookup, filter logic and configuration sources. Skipper identifies routes based on the requests’ properties, such as path, method, host and headers using the predicates. It allows the modification of the requests and responses with filters that are independently configured for each route. Skipper can be used to run as a Kubernetes Ingress controller. Details with examples of Skipper’s capabilities and an overview can be found in the ingress-controller deployment docs. -
