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

PromptLayer

  • The free plan is capped at only 2,500 requests per month, quite limited for active production use.
  • The Team plan jumps to $500/month, a large step up from the $49/month Pro plan.
  • Overage transaction fees apply on top of subscription costs, which can make total spend less predictable.
  • Enterprise-grade features like HIPAA BAAs and custom deployment require contacting sales.
