The short version

  • Each has a real cost: Heroku there is no free dyno tier; the cheapest Eco dyno is $5 per month; Lambda no free tier or trial, requiring immediate commitment for testing
  • They diverge on capability: Heroku covers Git-based deployment, Lambda covers Superclusters.
  • 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

Lambda

  • No free tier or trial, requiring immediate commitment for testing
  • Single-tenant Superclusters require custom pricing discussions
  • Pricing complexity across multiple GPU types and cluster sizes
  • Less suitable for experimentation or small teams with tight budgets

Questions people ask

Is Heroku or Lambda better?
Neither clearly leads. Heroku starts at $5/month and Lambda at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Heroku or Lambda?
Heroku starts at $5/month and Lambda at On request.
Does Heroku or Lambda run on more platforms?
Heroku runs on Web, Api, Workers. Lambda runs on Cloud.
What is Heroku best used for?
