Viscosity

Viscosity provides a graphical interface for creating, editing, and managing OpenVPN connections on macOS and Windows. Users can configure all connection parameters through the editor without needing to use command‑line tools, and the client displays real‑time traffic graphs, network statistics, and DNS settings. It supports advanced features such as IPv6, traffic obfuscation, multiple simultaneous connections, and a range of authentication methods.

The software is aimed at both novice users who want a simple way to secure their network and experienced administrators who need detailed control over VPN settings. It includes enterprise‑oriented capabilities like bundled profiles for easy deployment and a DNS system that can route queries through VPN servers or selectively per domain.

A distinctive aspect of Viscosity is its scripting support: AppleScript on macOS and VBScript on Windows can be used to automate actions and trigger custom scripts when a connection changes state, allowing integration with broader workflows and system automation.
