Where each one falls short

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

Amazon Lex

  • Pay-as-you-go model with no standard free tier, only AWS free credits for new customers (6 months, $200 limit)
  • Speech requests cost $0.004 each, text requests $0.00075 each, training costs $0.50 per minute
  • Variable costs can accumulate quickly for high-volume applications

Chatra

  • Free plan is capped at 5 chats per month and one agent seat
  • Essential and Pro tiers are billed per agent seat at $31/month and $41/month (or $25/month and $33/month if billed yearly), so cost rises directly with headcount
