  • Enterprise pricing is not disclosed; requires sales contact

RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription.
  • More resource-intensive than lightweight editors such as Sublime Text.

  • Startup time can be slower than simpler text editors on older hardware.
