The short version

  • Only Inkscape has a free tier, so it costs nothing to try first.
  • Each has a real cost: Inkscape no CMYK color mode support, making it unsuitable for professional print workflows requiring full color management; 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.
  • They diverge on capability: Inkscape covers Vector editing, Proto.io covers Event and condition system.
  • Prices and features above were last checked on 31 August 2026.

  • Validating a concept for a client who needs to feel the product, not watch a video of itnot Inkscape

Where each one falls short

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

Inkscape

  • No CMYK color mode support, making it unsuitable for professional print workflows requiring full color management
  • Lacks advanced features like 3D effects, Live Paint, and Live Trace found in Adobe Illustrator
  • Extension ecosystem is smaller and more fragmented than Illustrator's built-in advanced capabilities

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

Inkscape: Is Inkscape free and open source?

Yes, Inkscape is completely free and open source under the GPL license. There are no licensing fees or subscription costs.

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.

Inkscape: What file formats does Inkscape support?

Inkscape's native format is SVG (Scalable Vector Graphics). It can import and export AI, EPS, PDF, PS, PNG, and many other formats.

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.

Inkscape: Can Inkscape be used for professional print design?

Inkscape lacks CMYK color mode, which is required for professional print work. Adobe Illustrator is better suited for print design due to superior color management and CMYK support.

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.

Inkscape: What platforms does Inkscape run on?

Inkscape is available for Linux, macOS, and Windows. It runs on all major operating systems and is fully cross-platform.

Source
Inkscape: Does Inkscape have extensibility and plugins?

Yes, Inkscape has an extension system with community-built plugins. Extensions can be installed from the Extension Manager or downloaded manually, including tools for GCode generation, embroidery design (Inkstitch), and more.
