What people use each for

The jobs each tool is most often brought in to do.

Proto.io

  • Running usability tests where the prototype must respond to real input rather than replay a fixed click pathnot RubyMine
  • Demonstrating a form-heavy or data-driven flow to stakeholders before any code existsnot RubyMine
  • Testing a mobile interaction on the physical device it is designed for, with correct gesture behaviournot RubyMine
  • Validating a concept for a client who needs to feel the product, not watch a video of itnot RubyMine

RubyMine

  • Building and maintaining Ruby on Rails applicationsnot Proto.io
  • Debugging Ruby web applicationsnot Proto.io
  • Running and managing RSpec or Minitest suitesnot Proto.io
  • Working across Ruby, JavaScript, and SQL in one projectnot Proto.io

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Proto.io

  • Prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given
  • Design is done elsewhere and interaction is rebuilt here, so every change to the visual design has to be reapplied by hand and the two artefacts drift apart
  • The event and condition model is layer based, so a genuinely complex flow becomes a large tree of triggers that nobody but its author can audit
  • Editor seats are priced individually and viewer access is limited on lower plans, so opening review to a wide stakeholder group pushes you up a tier for people who never edit anything
  • The market standardised on Figma, so hiring people who already know Proto.io is progressively harder and every new researcher is a training cost

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

Answered from the vendors’ own pages

Proto.io: Can it replace Figma?

No. It has no design system or file-handoff role. It sits alongside Figma for the prototypes Figma cannot express.

RubyMine: How much does RubyMine cost?

RubyMine is sold as a JetBrains Toolbox subscription starting around $24/month for individuals and $34/month for organizations, with free licenses available for students and open-source maintainers.

Source
Proto.io: What happens to prototypes if we stop paying?

They stop being accessible unless you have exported them, and offline export is restricted to higher plans, so plan archiving before you cancel.

RubyMine: Is there a free trial?

JetBrains provides a free trial period for RubyMine so developers can evaluate it before purchasing a subscription.

Source
Proto.io: Is it worth learning now that InVision has gone?

If your work is usability research on conditional flows, yes. If you need click-through demos of static screens, Figma already does that at no extra cost.

RubyMine: What platforms does RubyMine support?

RubyMine runs as a desktop application on Windows, macOS, and Linux via JetBrains Toolbox.
