Viscosity (macOS) — Review

Viscosity is a paid, user-friendly OpenVPN and WireGuard client for macOS that focuses on reliability, customization, and clear diagnostics. It’s aimed at power users and IT pros who want more control than the built‑in VPN tools provide, while still being accessible to less technical users.

Pros

  • Compatibility: Works with OpenVPN and WireGuard configurations from most VPN providers and self-hosted servers.
  • Stable connections: Reliable reconnects and low CPU overhead in my tests.
  • Detailed diagnostics: Clear logs, connection statistics, and per-connection information make troubleshooting straightforward.
  • Granular control: Per-connection DNS, routing, and proxy options; scripting hooks for connect/disconnect events.
  • macOS integration: System tray menu, keychain support for storing credentials, and good support for macOS networking behaviors.
  • Import/export: Easy import of .ovpn/.conf files and export of connection bundles for team distribution.

Cons

  • Paid license: Requires purchasing a license key (no free tier beyond a trial), which may deter casual users.
  • UI feels dated: Functional but not modern-looking compared with some consumer VPN apps.
  • Manual setup for novices: Non-technical users may need help configuring providers that don’t supply ready-made config files.
  • Limited provider features: Doesn’t include built‑in server lists, adblocking, or automatic server selection like consumer VPN apps.

Performance and Reliability

  • Connection times are fast; reconnection after network changes is robust. CPU and memory usage are low relative to feature set. WireGuard sessions (when used) show excellent throughput.

Security and Privacy

  • Supports strong crypto via OpenVPN/WireGuard; credentials can be stored securely in the macOS Keychain. Security depends primarily on server/provider configuration. No telemetry in the app itself; review provider practices separately.

Who it’s best for

  • IT administrators, power users, and small teams who need reliable, configurable VPN clients and are comfortable importing config files or using company-issued profiles. Less ideal for users seeking a turnkey consumer VPN with integrated server lists and marketing features.

Bottom line Viscosity for macOS is a solid, dependable VPN client with advanced controls and excellent diagnostics. The paid license is reasonable for professionals who need stability and configurability; casual users may prefer a provider’s dedicated consumer app.
