Possible disadvantages of Instance

  • Limited market presence
    Instance is a relatively lesser-known platform compared to established competitors like Zapier or Make, which means fewer community resources, tutorials, and third-party support are available.
  • Smaller integration ecosystem
    Compared to more mature automation platforms, Instance may have a more limited library of pre-built integrations, potentially requiring more custom development for niche tools.
  • Limited documentation and resources
    As a newer or smaller platform, the available documentation, guides, and learning resources may not be as comprehensive as those offered by larger competitors.
  • Uncertain long-term viability
    Being a smaller player in the automation space raises concerns about long-term sustainability, ongoing development, and continued support compared to well-funded competitors.
  • Potential scalability concerns
    Users with enterprise-level needs may find limitations in terms of scalability, advanced features, or enterprise-grade support that more established platforms typically offer.

  • Most valuable skills in design?
    Before UX, I was an Industrial Designer. I used Solidworks and KeyShot (and some Unreal Engine for Arch Viz). If you don't plan on doing Arch Viz or serious ID, then you should look at other 3D programs that's easier to learn. Check out: https://spline.design/, Adobe's (I forgot which one), or Vectary. I personally prefer Spline. I haven't touched it in awhile though cos I have been coding more lately. Source: over 2 years ago
