Where each one falls short

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

Heroku

  • There is no free dyno tier; the cheapest Eco dyno is $5 per month
  • Eco dynos sleep after 30 minutes of inactivity, are restricted to personal accounts and allow only 2 process types
  • Free SSL and 10 process types start at the Basic dyno at $7 per month
  • Private and Shield dyno types require a Private Space, which is billed on top of the dynos
  • Private Space dynos start at $250 per month for Private-M and $500 per month for Private-L
  • Dyno prices are per dyno per month, so an app with several process types multiplies the bill

Resemble AI

  • The Team plan jumps to $350/month for just 5 seats, a steep increase from the free Flex tier.
  • Detection accuracy rates (99.5% audio, 98% video, 96% image) mean some deepfakes can still go undetected.
  • SSO and org-wide security features are only available starting on the $1,000/month Business plan.
  • Voice cloning of another person's voice requires explicit consent verification, adding friction to some workflows.
