The short version

  • Only Upstash has a free tier, so it costs nothing to try first.
  • Each has a real cost: Carbonite upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading; Upstash hTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis
  • They diverge on capability: Carbonite covers Automatic backup, Upstash covers Serverless Redis.

Where each one falls short

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

Carbonite

  • Upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading
  • Bandwidth throttling control is limited, preventing users from managing full bandwidth allocation
  • Mobile apps and web access are more limited than sync-first services like Dropbox or Google Drive
  • Uses AES-128 encryption instead of industry-standard AES-256
  • Hybrid backup support is restricted to professional plans, unavailable for personal users

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

Source
Upstash: Is Upstash Kafka still available?

No. Upstash Kafka was deprecated on September 11, 2024 and fully discontinued on March 11, 2025. Upstash Workflow is now recommended for durable serverless messaging and task queuing.
