What people use each for

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

Vim

  • Configuration system uses keyboard mappings with no graphical interface for settings
  • Requires browsing documentation to modify even basic settings
  • Lacks sensible defaults for many common configurations
  • Plugin ecosystem stability varies widely depending on custom configuration complexity

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.

Vim: Is Vim free and open source?

Yes, Vim is free and open source, distributed under a charityware license. The creator requested donations to ICCF Holland, a non-profit supporting AIDS victims in Uganda. All donations are forwarded to ICCF.

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.

Vim: What platforms does Vim support?

Vim runs on Unix-like systems (Linux, macOS, BSD), Windows (7, 8, 10, 11), VMS, and is available through package managers or standalone installation on all major operating systems.

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.

Vim: Who maintains Vim now?

Vim was created by Bram Moolenaar, who passed away on August 3, 2023. Christian Brabandt is the current lead maintainer, and the project continues with volunteer contributors.
