    Barrier

    Barrier

    Open-source KVM software

    Barrier is a software that works just like a KVM (keyboard, video and mouse) switch, which allows you to use a single mouse and keyboard to control several different computers by physically turning a dial on the box to switch the machine you're controlling at any given time. Barrier is able to do this in software, giving you control over different machines by simply moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system. Barrier was built to be simple and reliable, allowing you to control a different machine by simply using your mouse and keyboard from another. It works on all major operating systems (Linux, Windows, MacOS/OS X), including FreeBSD and OpenBSD.

    Zapret

    Zapret

    Advanced open source tool for bypassing DPI-based censorship

    Zapret is an open source, cross-platform tool designed to help users bypass and evade Deep Packet Inspection (DPI)-based traffic blocking and censorship systems. Rather than acting as a traditional proxy or VPN, it works by manipulating network packets and traffic streams locally to confuse or disrupt DPI mechanisms used by ISPs and network filters, making it possible to access restricted websites and services without relaying traffic through third-party servers. Zapret implements multiple strategies including desynchronizing DPI inspection, packet modification, and protocol manipulation to make network traffic less recognizable or harder for DPI systems to classify reliably. It supports deployment on a variety of operating systems including traditional Linux systems, embedded devices like routers running OpenWRT, and has partial support for FreeBSD, OpenBSD, macOS, and Windows.
