Zapret Discord YouTube
Windows-based network traffic manipulation tool
Zapret Discord YouTube is a Windows-based network traffic manipulation tool designed to bypass internet restrictions and throttling applied to services such as YouTube and Discord by modifying how traffic is handled at the packet level. The project is built on top of the broader “zapret” ecosystem and uses WinDivert, a low-level packet interception driver, to filter, split, and alter network packets in real time in order to evade deep packet inspection (DPI) systems used by ISPs or governments. By applying different “strategies” through batch scripts, the tool can dynamically adjust how traffic appears to filtering systems, effectively restoring access or improving connection quality for blocked or slowed services. ... -

AmneziaWG Go
AmneziaWG VPN protocol
AmneziaWG Go is the Go implementation of the AmneziaWG VPN protocol. It is based on WireGuard-Go but adds traffic obfuscation features intended to make VPN traffic harder to detect by Deep Packet Inspection systems. The project keeps WireGuard’s general simplicity and performance goals while changing packet behavior to reduce recognizable protocol signatures. It can create and run tunnel interfaces from the command line and can be configured with AmneziaWG tools or standard network utilities. The implementation supports platform-specific behavior for Linux, macOS, and Windows, although each platform has its own recommended integration path. ... -

kcptun
A stable and secure tunnel based on KCP with N:M multiplexing and FEC
kcptun is a stable and secure tunnel based on KCP with N:M multiplexing and FEC. Available for ARM, MIPS, 386 and AMD64. kcptun is shipped with builtin packet encryption powered by various block encryption algorithms and works in Cipher Feedback Mode, for each packet to be sent, the encryption process will start from encrypting a nonce from the system entropy, so encryption to same plaintexts never leads to a same ciphertexts thereafter. kcptun made use of ReedSolomon-Codes to recover lost packets, which requires massive amount of computation, a low-end ARM device cannot satisfy kcptun well. ... -

Flowseal
Bypass regional or ISP-level restrictions on services like Discord
Flowseal is a community-hosted repository that provides tools and scripts intended to help users bypass regional or ISP-level restrictions on services like Discord and YouTube, commonly blocked in certain countries or networks. It packages configurations and executable scripts (e.g., batch files) that leverage system-level filtering or packet redirection techniques (such as WinDivert or other strategies) to modify network behavior so that traffic destined for these services appears indistinguishable from unrestricted traffic. The project includes ways to install system services, update host rules, and test different strategies for unblocking or rerouting traffic. Because it directly touches network stacks and routing, its usage is typically technical and can require careful configuration to avoid destabilizing network settings. -

paqet
Ferries Packets Across Forbidden Boundaries
paqet is a bidirectional packet-level proxy that transports traffic over raw packets instead of relying on the host operating system’s normal TCP/IP stack. It forwards traffic between a local client and a remote server using KCP as the reliable transport layer. The project is written in Go and is aimed at users who need a low-level tunnel that can operate in restricted or heavily filtered network environments. -

It uses a custom protocol with ARQ, low overhead, resolver balancing, and multipath behavior to improve performance under packet loss. MasterDnsVPN also includes client and server configuration files, Docker support, and installation scripts for easier deployment. It is best understood as an experimental transport system for DNS-based tunneling rather than a general-purpose commercial VPN. -

KCP
A fast and reliable ARQ protocol
...It is implemented by using the pure algorithm, and is not responsible for the sending and receiving of the underlying protocol (such as UDP), requiring the users to define their own transmission mode for the underlying data packet, and provide it to KCP in the way of callback. Even the clock needs to be passed in from the outside, without any internal system calls. The entire protocol has only two source files of ikcp.h, ikcp.c, which can be easily integrated into the user's own protocol stack. You may have implement a P2P, or a UDP-based protocol, but are lack of a set of perfect ARQ reliable protocol implementation, then by simply copying the two files to the existing project, and writing a couple of lines of code, you can use it. -

Wiretap
Wiretap is a transparent, VPN-like proxy server that tunnels traffic
Wiretap is a transparent, VPN-like proxy server that tunnels traffic through WireGuard. It is designed to proxy traffic without requiring special privileges to run, which makes it different from many traditional VPN tools that depend on privileged network interface setup. The project focuses on transparent routing, allowing client traffic to move through WireGuard-based paths toward the intended destination. Its documentation describes an end-to-end encryption model where packets are... -

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. ... -

PyNuker
A stress testing tool written in python.
...Because it is written in python it should run equally well on any system that has Python version 3.x installed. It infinitely(until stopped) sends a string of text via a UDP packet to a target computer or network device in an effort to flood the target with so much useless traffic that it stops responding to valid requests.
