Where each one falls short

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

Black Forest Labs

  • Open weights licensing tiers (Builder, Platform, Professional) do not list public prices, requiring sales contact for most volumes.
  • Video generation pricing per second can become costly for longer or higher-resolution outputs compared to subscription-based competitors.
  • No consumer subscription plan; pricing is oriented toward developers and enterprises rather than casual creators.

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
