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

Voiceflow

  • The free plan is limited to a single active workspace collaborator, so team collaboration requires upgrading to the paid Pro or Team tiers
