RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription
  • More resource-intensive than lightweight editors such as Sublime Text
  • Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead
  • Startup time can be slower than simpler text editors on older hardware
