No public documentation on pricing or feature tiers

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.
