The short version

  • Eclipse is free; Proto.io prices on request.
  • Only Eclipse lists java development environment; only Proto.io lists event and condition system.
  • Where Eclipse falls short: high memory consumption and CPU usage, especially with multiple plugins installed.
  • Prices and features on this page were last checked on 13 November 2026.

Proto.io

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

Where each one falls short

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

Eclipse

  • High memory consumption and CPU usage, especially with multiple plugins installed
  • Slow startup times and performance degradation with large projects or many open editors
  • Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
  • User interface considered outdated compared to modern IDE alternatives
  • User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline

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

Answered from the vendors’ own pages

Eclipse: How much does Eclipse IDE cost?

Eclipse IDE is completely free and open-source, released under the Eclipse Public License 2.0.

Source
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.

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.

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.
