Pros

  • The platform is incredibly easy to set up, often requiring just a few lines of code to add to a Ruby on Rails, Elixir, or Node.js application .
  • It has a clear and user-friendly interface that makes it easy for developers to understand performance issues and deploy fixes .
  • It provides a comprehensive set of tools including error tracking, performance monitoring, and host metrics, all in one platform .

Cons
