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

Writer

Pricing is not publicly disclosed and requires a sales conversation, unlike consumer AI writing tools.
Its proprietary Palmyra models are less widely benchmarked and documented than general-purpose models like GPT or Claude.
Primarily positioned for large enterprises, making it less accessible or cost-effective for individuals and small teams.
