📦 Upstash

3 guides covering real-world deployment patterns, gotchas, and integration decisions for Upstash.

Upstash offers three serverless data products: Redis (for caching, sessions, and rate limiting), QStash (HTTP-based message queue with guaranteed delivery), and Vector (serverless vector database for RAG pipelines). All are priced per request with no always-on server cost.

  • Serverless Redis: per-request pricing, global replication, REST API
  • QStash: HTTP message queue with at-least-once delivery and deduplication
  • Vector DB: serverless vector store for RAG and semantic search pipelines
  • Rate limiting helpers for Next.js middleware and API routes
  • Free tier covers generous request limits across all three products
