Where each one falls short

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

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward

Render

  • The free Hobby workspace is limited to 25 services and 5 GB of bandwidth
  • Every paid plan charges the workspace fee plus compute on top, so $25 per month for Pro is a floor rather than a total
  • SAML SSO and SCIM require the Scale plan at $499 per month
  • HIPAA-compliant workspaces, inbound IP rules and advanced RBAC roles are Scale plan features
  • Organization-level audit logs require Scale; Pro provides only workspace audit logs
  • Contractual uptime SLAs, support response SLAs and a technical account manager are Enterprise only, and Enterprise is custom priced with no published rate
  • Included bandwidth is 25 GB on Pro and 1 TB on Scale, with usage beyond that billed separately
