Where each one falls short

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

Harness

  • Essentials and Enterprise pricing requires sales contact; no published rates
  • DevOps Essentials has no on-premises deployment option
  • Internal Developer Portal requires minimum 20 developer licenses
  • Pipeline execution history retention 6 months (Essentials) vs 25 months as add-on (Enterprise)

Upstash

  • HTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis
  • Rate limiting occurs when traffic exceeds configured budget cap or request limits
  • Kafka service discontinued in March 2025, requiring migration to Upstash Workflow or alternatives
  • Limited Redis feature support compared to self-hosted Redis or Redis Cloud
  • High-request-volume workloads can accumulate significant costs due to per-request pricing model
