Upstash Serverless Data

Upstash is a serverless data platform founded by Enes Akar and Ediz Eren in 2021, backed by investors including Y Combinator and Catapult Ventures, providing serverless Redis and serverless Kafka with per-request pricing, global edge deployment, and REST API access designed for serverless and edge computing environments where persistent connections and traditional connection pooling are not available, adopted by over one hundred thousand developers and companies including Vercel, Cloudflare, and Auth0 for their caching, rate limiting, and messaging needs in serverless architectures. The serverless Redis provides a Redis-compatible API accessible through both standard Redis protocol connections for traditional clients and a REST API for environments that cannot maintain persistent connections including Cloudflare Workers, Vercel Edge Functions, Deno Deploy, and browser-side applications, with the REST API enabling Redis operations including GET, SET, DEL, INCR, EXPIRE, and all standard commands through HTTP requests, eliminating the need for connection pooling in serverless environments. The pricing model charges per request rather than per instance or per hour, with a free tier providing ten thousand commands per day, making it cost-effective for applications with sporadic or unpredictable traffic patterns, with automatic scaling from zero to thousands of requests per second without configuration. The serverless Kafka provides Kafka-compatible topics with REST proxy for publishing and consuming messages, designed for event-driven serverless architectures. The global edge deployment places data close to users across multiple regions. The QStash for reliable HTTP-based message queuing. The Vector database for AI embeddings. The rate limiting SDK. Designed for serverless and edge developers.
