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.

Rebelle

  • Exact prices not displayed on product page, must contact for quote
  • Lifetime license model with no subscription option provides no recurring revenue basis for vendor updates

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.

Rebelle: What is Rebelle's pricing model?

Rebelle uses a lifetime one-time purchase model with two editions: Rebelle 8 and Rebelle 8 Pro. Exact prices are not published on the product page. Educational licenses receive 40 percent discount. Both editions include free updates for one year and a 30-day money-back guarantee.

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.

Rebelle: Can I use Rebelle on multiple computers?

Each Rebelle license covers 3 computers. Additional computers require separate licenses or contacting the vendor for multi-seat options.

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.
