Temporal

  • Cloud pricing scales with action volume, with per-million overage fees ($50 per million initially)
  • Enterprise customers incur additional storage costs beyond base allocations
  • Self-hosted deployments require operational expertise to deploy and maintain the Temporal Service
  • No native workflow UI builder; workflows must be defined in code
  • Free tier limited to self-hosted option only; no free cloud tier
