Open Source Python VPN Software

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.

The Proton VPN GTK App repository contains the official Linux desktop client for ProtonVPN using the GTK toolkit, allowing users of GNOME, XFCE, and other Linux desktop environments to connect securely to Proton’s VPN servers with a native-looking interface. Built with Python or C and leveraging the GTK framework, this app provides intuitive controls for server selection, connection management, and status reporting, integrating with Linux system networking and user session environments. It supports features expected of a full VPN client—such as secure tunnels, automatic reconnection, and location selection—while respecting desktop conventions like system tray icons and notifications. The GTK client helps bring ProtonVPN’s privacy-focused service to the Linux ecosystem in a way that fits naturally with widely used Linux DEs, making secure connectivity accessible to users who prefer open systems for development, business, or privacy reasons.

Introducing Algo, a self-hosted personal VPN server designed for ease of deployment and security. Algo automatically deploys an on-demand VPN service in the cloud that is not shared with other users, relies on only modern protocols and ciphers, and includes only the minimal software you need. And it’s free. For anyone who is privacy conscious, travels for work frequently, or can’t afford a dedicated IT department, this one’s for you. Really, the paid-for services are just commercial honeypots. If an attacker can compromise a VPN provider, they can monitor a whole lot of sensitive data. Paid-for VPNs tend to be insecure: they share keys, their weak cryptography gives a false sense of security, and they require you to trust their operators. Even if you’re not doing anything wrong, you could be sharing the same endpoint with someone who is. In that case, your network traffic will be analyzed when law enforcement makes that seizure.

Endian Firewall Community (EFW) is a "turn-key" linux security distribution that makes your system a full featured security appliance with Unified Threat Management (UTM) functionalities. The software has been designed for the best usability: very easy to install, use and manage and still greatly flexible. The feature suite includes stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spam-filtering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on both OpenVPN and IPsec).

CacheGuard Gateway is a free and open-source Unified Threat Management (UTM) solution, a Web Application Firewall (WAF), and a Quality of Service (QoS) platform designed to optimize WAN traffic. To obtain a CacheGuard Gateway appliance, download CacheGuard-OS and install it on the bare-metal or virtual machine of your choice. It’s that simple and completely free. The UTM includes a firewall, web antivirus, VPN server, and a URL-filtering and SSL-inspection web proxy. The WAF operates in conjunction with a reverse proxy, web application load balancer, and SSL offloader, and is capable of blocking malicious requests as well as traffic from IP addresses with poor reputations. The QoS manager enables traffic shaping to prioritize critical network flows, load balance multiple WAN links, and cache web traffic.

openvpn-monitor is a simple Python program to generate HTML that displays the status of an OpenVPN server, including all current connections. It uses the OpenVPN management console. It typically runs on the same host as the OpenVPN server, however, it does not necessarily need to. OpenVPN-monitor is a web-based OpenVPN monitor, that shows current connection information, such as users, location, and data transferred.
