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
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. -

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
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). -

Elegant cross-platform proxy GUI client that supports Shadowsocks
We use Clash as the backend proxy, which supports Shadowsocks(R), V2Ray, and Trojan protocols. V2Ray Desktop is a cross-platform GUI client that supports Shadowsocks(R), V2Ray, and Trojan protocols, running on Windows, Linux, and macOS. It is built with Qt 5 and QML 2. Compared to V2Ray, V2Ray Desktop provides more advanced features such as server subscription and latency test. You can easily migrate to V2Ray Desktop from Shadowsocks-Qt5 and V2Ray Core by importing their config files. Some functions (e.g., server subscription) in the prebuilt binary packages require OpenSSL >= 1.1.0. If you are using Ubuntu<=18.04, please install OpenSSL manually. You can refer to Installation Guide in the Wiki page for the detailed information. -

JavDB
javdb official app
JavDB is an open-source mobile application designed as an official client for browsing and interacting with the JavDB platform, providing users with a streamlined interface for accessing and managing content from the associated database. The project focuses on delivering a dedicated app experience rather than relying on web browsing, allowing for improved navigation, performance, and usability on mobile devices. It includes distribution options through various channels such as direct downloads, third-party installers, and release builds, making it accessible across different user environments. The application is relatively lightweight and centered around providing quick access to indexed content, metadata, and media listings available on the platform. Its development is maintained through a GitHub repository with ongoing releases and updates, indicating active iteration and refinement. -

Streisand
Streisand sets up a new server running your choice
Streisand is a tool that automates the deployment of censorship-resistant VPN services on cloud servers. It was created to help users bypass internet censorship and surveillance by quickly setting up secure communication channels without needing deep system administration expertise. With just a cloud provider account and basic Unix command-line knowledge, Streisand can provision a server and configure multiple VPN and proxy protocols almost automatically. This includes OpenVPN, WireGuard, Shadowsocks, OpenConnect, and Tor bridges, often with optional add-ons like obfuscation or stunnel to resist throttling and detection. The result is a private website that hosts client software downloads and setup instructions for easy access. Streisand supports major cloud providers like AWS, Azure, Google Cloud, Linode, DigitalOcean, and Rackspace, while also offering installation options for advanced users with their own servers.
