    KeePass

    KeePass

    A lightweight and easy-to-use password manager

    KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

    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.

    Proton VPN for iOS and macOS

    Proton VPN for iOS and macOS

    Official ProtonVPN iOS and macOS app

    The ProtonVPN iOS and macOS project contains the official code for the unified VPN client used on Apple platforms, delivering secure, encrypted network connections to Proton’s global servers directly from iPhones, iPads, and Macs. Written primarily in Swift with Apple platform conventions, this client lets users authenticate with their Proton accounts, select server locations, and manage advanced privacy features like automatic reconnection and DNS leak protection, tailored for Apple’s networking APIs. Because iOS and macOS have strict networking and extension models, the app uses system VPN configurations and integrates with native controls for background operation, seamless switching, and efficient battery usage. It supports both free and premium tiers of ProtonVPN, offering users flexible connection options while preserving Proton’s strict no-logs privacy policies.

    Flowseal

    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.

    Tor Browser

    Tor Browser

    Browser for using Tor on Windows, Mac OS X or Linux

    Tor Browser enables you to use Tor on Windows, Mac OS X, or Linux without needing to install any software. Tor is a software that bounces your communications around a distributed network of relays run by volunteers. This effectively prevents anyone watching your Internet connection from learning what sites you visit; it prevents the sites you visit from learning your physical location; and allows you access to sites which are blocked. Tor Browser can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).

You can refer to Installation Guide in the Wiki page for the detailed information.
