The short version

  • Only Modal has a free tier, so it costs nothing to try first.
  • Each has a real cost: Modal the Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute; Porter pricing based on vCPU and memory can be expensive for small projects
  • They diverge on capability: Modal covers Serverless GPUs, Porter covers Rapid deployment.
  • 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.

Modal

  • The Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute
  • Compute is billed per second across separate GPU and CPU meters, so total cost depends on execution time rather than any fixed rate
  • The Starter plan's $30 monthly free credit is the only allowance below the paid base fee
  • Enterprise volume discounts are custom and unpublished

Porter

  • Pricing based on vCPU and memory can be expensive for small projects
  • Vendor lock-in to Porter platform despite multi-cloud support
  • Limited customization for complex infrastructure requirements
