Possible disadvantages

  • Dependency on TailScale's Infrastructure
    Using TailScale requires reliance on their central coordination servers for initial connection setup and identity management. This could be a concern if the service experiences downtime or other issues.
  • Privacy Concerns
    Since TailScale routes initial connection metadata through their servers, some users may have privacy concerns, especially in highly sensitive environments.
  • Cost
    While TailScale offers a free tier, advanced features and larger-scale deployment options can be costly, potentially making it less suitable for budget-conscious users.
  • Limited Advanced Configuration
    TailScale's simplicity can be a downside for advanced users who require granular control and configuration options that go beyond what TailScale's interface offers.
  • Proprietary Software
    TailScale is a commercial product with proprietary elements, which might not appeal to open-source enthusiasts or organizations that prefer fully open-source solutions.
