  • Lack of Built-In Servers
    Viscosity does not provide its own VPN servers, requiring users to rely on third-party VPN service providers for the actual server connections.

    OpenConnect primarily operates via the command line and lacks a comprehensive graphical user interface (GUI), which might be a disadvantage for users who prefer graphical tools.
  • Documentation Variability
    While there's documentation available, users might find inconsistencies or gaps due to the decentralized nature of contributions, making troubleshooting less straightforward.
  • Feature Parity
    In certain cases, OpenConnect may lack some features present in the proprietary VPN clients it aims to replace, potentially limiting functionality for some advanced configurations.
