Where each one falls short

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

HeyGen

Avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds
Cannot reliably choreograph natural interactions like walking through a room, using devices, or drinking from objects
Billing gap between marketed unlimited plans and actual credit consumption is highest complaint with lost credits on failed renders
Inconsistent lip sync and voice quality with slow processing and occasional moderation blocks without explanation
Customer support described as non-existent with no way to complain or reach a human representative

Upstash

HTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis
Rate limiting occurs when traffic exceeds configured budget cap or request limits
Kafka service discontinued in March 2025, requiring migration to Upstash Workflow or alternatives
Limited Redis feature support compared to self-hosted Redis or Redis Cloud
High-request-volume workloads can accumulate significant costs due to per-request pricing model
