Tailscale
The easiest, most secure way to use WireGuard and 2FA
Tailscale is an open-source zero-configuration VPN and networking solution that makes it simple to create secure, private networks across devices by leveraging WireGuard under the hood. It lets users connect computers, servers, mobile devices, and cloud instances together with peer-to-peer encrypted tunnels without dealing with complex firewalls, NAT rules, or key distribution headaches. Instead of traditional VPN server infrastructure, Tailscale uses a coordination service to authenticate devices and exchange connection information, enabling automatic NAT traversal and minimal manual setup. The project includes a daemon (tailscaled) and a CLI tool that run on major operating systems, and it also forms the basis for the official clients on platforms like iOS and Android, though those have GUI wrappers not fully in this repository. -

Proton VPN Browser Extension
Proton VPN Browser Extension
The Proton VPN Browser Extension repository houses the code for an official browser extension that lets users quickly secure their web browsing traffic through ProtonVPN from within browsers like Firefox and Chrome without routing all system traffic. This extension provides users with a convenient way to encrypt and anonymize HTTP requests, hide IP addresses, and prevent tracking while browsing, acting independently of the full OS-level VPN clients. Because browser extensions are constrained by browser APIs, this extension focuses on securing in-browser connections, protecting privacy specifically within the browser context rather than across the entire operating system. Users can sign in with their Proton accounts, choose from available VPN locations, and connect or disconnect from the toolbar with a single click, making it practical for casual privacy protection or geo-unblocking content without installing native applications. -

OpenFortiVPN
Client for PPP+TLS VPN tunnel services
openfortivpn is a command-line SSL VPN client for connecting to Fortinet FortiGate gateways without relying on proprietary GUIs. It negotiates the SSL/TLS tunnel, authenticates with credentials (and commonly with two-factor methods), then brings up a secure point-to-point interface and installs routes and DNS settings. The tool aims to be minimal and dependable: a single binary with an INI-style config file, systemd compatibility, and clear runtime diagnostics. It handles details like MTU tuning, split tunneling via pushed routes, and reconnect logic to keep the session stable. Because it works with the standard tun interface, it integrates smoothly with common Linux networking stacks and pairs well with desktop frontends such as NetworkManager plugins. For admins and developers, it’s a scriptable, cross-platform-friendly alternative that makes FortiGate access reliable on servers and developer workstations alike. -

WireGuard Go
This is an implementation of WireGuard in Go
WireGuard-Go is the official userspace implementation of the WireGuard VPN protocol written in Go, providing a portable alternative to kernel-level deployments. The project enables systems that cannot run the native kernel module to still create secure WireGuard tunnels by operating entirely in user space. When executed, the program creates a virtual network interface that can be configured using standard networking tools such as wg and ip, closely mirroring the behavior of kernel implementations. The software is part of the broader WireGuard ecosystem, which aims to deliver a fast, simple, and modern VPN built on state-of-the-art cryptography. Because it runs in user space, wireguard-go is especially useful for platforms like macOS, Windows, or restricted environments where kernel modules are unavailable. -
