The short version

  • Each has a real cost: Heroku there is no free dyno tier; the cheapest Eco dyno is $5 per month; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs
  • They diverge on capability: Heroku covers Git-based deployment, WarpBuild covers Optimized runner infrastructure.
  • Prices and features above were last checked on 30 August 2026.

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

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer
