Upstash Redis
Upstash Redis is a fully managed, serverless Redis database in the cloud, with durable storage and pay-per-request pricing. It accepts connections over HTTP REST and the standard Redis TCP protocol. Databases can be replicated across regions for low-latency reads near users; the product describes multi-zone replication, automatic failover and persistence through restarts and failures. Listed use cases include caching, rate limiting, queues and streams, session storage, search and AI agent memory. It supports the Redis client protocol through version 8.4 and adds Search and Vector command families. Any Redis client can connect, including clients for TypeScript, Python, Go and Java. A Vercel integration can create or connect databases and expose environment variables to Vercel projects. TLS is enabled by default and cannot be turned off. The Free plan provides 256 MB of data, 10 GB of monthly bandwidth and 500K monthly commands. Pay as You Go is billed at $0.20 per 100K commands; storage and bandwidth charges may also apply. Its headquarters are in California.
