Where each one falls short

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

Railway

  • Plan fees are usage credits rather than allowances, so the $5 Hobby and $20 Pro fees are spent on compute and anything beyond is billed on top
  • The free plan carries $1 of monthly credit and caps a service at 1 vCPU and 0.5 GB
  • Compute is metered per second for both memory and CPU, so cost tracks uptime rather than traffic and an idle service still bills
  • Egress is $0.05 per GB on top of compute
  • The Pro fee is per workspace rather than per user or per project

Voiceflow

  • The free plan is limited to a single active workspace collaborator, so team collaboration requires upgrading to the paid Pro or Team tiers
