Where each one falls short

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

Deepgram

  • Pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
  • Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.
  • Some promotional per-minute rates are time-limited, meaning long-term pricing may differ from current promotional rates.

Slack Workflow Builder

  • Limited to Pro and above pricing tiers, requiring paid Slack subscription
  • Maximum 15 conditional branches per workflow, limiting complex logic paths
  • Connectors must be explicitly configured per integration type
  • No native web interface for non-Slack users
