    As a niche project, sish may not have as large of a community or as many resources available for troubleshooting as more popular alternatives.
  • No Built-In Analytics
    Unlike some other tunneling services, sish does not provide built-in analytics or monitoring tools, requiring users to implement their own solutions.
