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

Cartesia

  • Instant and professional voice cloning are gated behind paid Pro and Startup tiers, unavailable on the free plan.
  • Voice agent calls carry a separate per-minute usage fee ($0.06/minute) on top of subscription credits.
  • Enterprise features like SSO and BAAs require a custom sales conversation rather than self-serve upgrade.
  • Free tier concurrency limits (2 TTS, 8 STT concurrent requests) may be restrictive for testing production-like load.
