Caddy 7 features

Possible disadvantages

  • Learning Curve for New Features
    As Caddy rapidly evolves and adds new features, there can be a learning curve associated with keeping up to date on the latest changes and functionalities.
  • Performance
    Although Caddy performs adequately for many use cases, it may not match the high performance of optimized setups with other web servers like Nginx in highly demanding environments.
  • Licensing Costs
