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

Conferbot

  • The free plan is capped at 600 conversations per month and a single seat, which limits it to very small operations.
  • Advanced features like custom branding and A/B testing require the Pro tier or higher rather than being available at entry-level paid plans.
  • Extra conversations beyond plan limits are billed per-unit ($0.01 each on Starter/Pro), which can make costs unpredictable at scale.
  • The platform lacks the deep enterprise conversational-AI training and analytics depth of larger incumbents like Intercom or Drift.
  • Voice channel support is not part of the core channel list, which is limited to website and text-based messaging apps.
