Where each one falls short

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

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.

Zapier

  • The free plan allows 100 tasks per month and only two-step Zaps, one trigger and one action
  • Multi-step Zaps, filters, paths, webhooks and the formatter all require a paid plan
  • Premium app connectors are withheld from the free plan
  • Free Zaps poll for new data every 15 minutes against 2 minutes on Professional and 1 minute on Team
  • Paying monthly rather than annually costs 50 percent more, so the 2,000-task Professional plan is $73.50 a month instead of $49
