The short version
- Each has a real cost: Upstash hTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis; 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.
- They diverge on capability: Upstash covers Serverless Redis, FaunaDB covers ACID Transactions.

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