About Viscosity

Viscosity, made by SparkLabs, is a desktop client for connecting to OpenVPN servers. It isn't a VPN service itself: you bring connection profiles from your workplace, home server or VPN provider, and Viscosity handles importing, editing and monitoring them. It's written natively for macOS and Windows and lives in the menu bar or system tray, with a details window showing traffic graphs and connection statistics. Features go well beyond the basic OpenVPN client: full and split DNS modes, several simultaneous connections, traffic obfuscation for networks that block VPNs, smartcard, token and U2F authentication, and scripts that run when a connection changes state, written in AppleScript on Mac or Batch and VBScript on Windows. IT teams can bundle it with preconfigured connections and deploy it through MDM or Group Policy. It's a one-time purchase per user, with a free 30-day trial and no subscription. There are no Linux, iOS or Android versions.

Best for: Mac and Windows users or IT teams who connect to OpenVPN servers and want a polished, scriptable client.
