Upstash REST API
Serverless REST APIs for Redis, Kafka, and QStash (message queuing) with per-request pricing — designed for edge functions and serverless environments where persistent connections aren't possible.
Best When
You're building serverless or edge applications (Vercel, Cloudflare Workers, AWS Lambda) that need Redis or Kafka without persistent connections.
Avoid When
You have traditional server infrastructure where native Redis/Kafka clients are available and preferred.
Use Cases
- • Caching with Redis in Vercel Edge Functions or Cloudflare Workers
- • Reliable job queuing with QStash for serverless workflows
- • Pub/sub messaging in serverless environments without connection management
- • Rate limiting and session storage at the edge
- • Serverless Kafka for event streaming without infrastructure
Not For
- • High-frequency Redis operations where TCP connection is viable (latency overhead)
- • Replacing a full Redis or Kafka deployment for traditional server apps
- • Teams needing self-hosted or on-prem infrastructure
