The short version

  • Only Vectr has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Vectr performance issues: slowness during edits is a recurring complaint, especially problematic for complex designs
  • They diverge on capability: Proto.io covers Event and condition system, Vectr covers Vector drawing.
  • Prices and features above were last checked on 31 August 2026.

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.

Vectr

  • Performance issues: slowness during edits is a recurring complaint, especially problematic for complex designs
  • Limited advanced features: lacks some features available in paid tools like Adobe Illustrator including complex shape manipulation
  • Internet dependency: requires constant internet connection with no offline capabilities limiting use in unreliable connectivity areas
  • Limited export options: fewer export formats compared to other vector graphics software
  • Limited integration: does not offer seamless integration with other design tools and lacks third-party extension support

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.

Vectr: Is Vectr free to use?

Vectr offers a free plan with 1GB storage, basic tools, and limited AI credits for essential vector editing. Paid Plus and Premium plans provide additional storage, AI credits, and concurrent sessions.

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.

Vectr: Can you collaborate in real-time with Vectr?

Yes, Vectr features built-in real-time collaboration with live workspace sharing through custom URLs and integrated chat for team communication, enabling distributed creative teamwork.

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.

Vectr: Does Vectr require an internet connection?

Yes, Vectr requires constant internet connection as it is cloud-based. It does not have offline capabilities, which can be limiting for users in areas with unreliable connectivity.

Source
Vectr: What file formats can you export from Vectr?

Vectr supports exporting in SVG, PNG, JPG, and Vectr SVG formats. Compared to other vector graphics software, export options are somewhat limited.
