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.

Rive

Limited ecosystem of plugins and third-party templates compared to established tools like After Effects
Not ideal for simple looping animations or static graphics that do not require interactivity
Production use can expose bugs and rough edges in the editor and runtime
No support for 3D animations; limited to 2D vector-based graphics
