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. It also integrates additional mechanisms such as host file updates and DNS configuration to improve compatibility with voice services and regional routing issues. -

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. -
