Upstash: Serverless Data Platform

Upstash is a serverless data platform providing Redis and Kafka APIs optimized for serverless and edge environments with per-request and pay-what-you-use pricing models. Upstash Redis offers durable storage with a REST API eliminating connection management issues common in serverless environments. Upstash Kafka provides fully managed Kafka topics with a REST API and SDKs for publishing and consuming messages without managing brokers. The platform is designed specifically for serverless functions that need ephemeral persistent storage.
