The short version

  • Each has a real cost: FaunaDB the Internet Archive's capture of FaunaDB's homepage on 5 January 2019 confirmed a free 'Try Cloud' tier alongside a self-hosted download, with a separate Pricing page linked but not itself retrievable from the archive within two attempts.; Upstash hTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis
  • They diverge on capability: FaunaDB covers ACID Transactions, Upstash covers Serverless Redis.

Where each one falls short

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

FaunaDB

  • The Internet Archive's capture of FaunaDB's homepage on 5 January 2019 confirmed a free 'Try Cloud' tier alongside a self-hosted download, with a separate Pricing page linked but not itself retrievable from the archive within two attempts.

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
