Where each one falls short

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

Balsamiq Wireframes

  • Starter plan is capped at 10 projects and costs $16 per editor per month ($192/year)
  • Teams plan raises the cap to only 100 projects at $24 per editor per month; even Enterprise tops out at 400 projects
  • AI credits are metered per editor per month (500 on Starter, 1,000 on Teams, 2,500 on Enterprise), so AI features have a hard usage ceiling beyond the base seat price

PaintTool SAI

  • Windows-only software with no native Mac or Linux version.
  • Only supports 32-bit operation, lacking modern 64-bit performance benefits.
  • Lacks the advanced brush engine customization and layer effects found in tools like Photoshop or Clip Studio Paint.
  • No cloud sync or mobile app, unlike many modern illustration tools.
