Upstash

Upstash provides serverless data services — including Redis, Kafka, and a vector database — designed specifically for the serverless and edge computing era, with pricing based on what you actually use rather than always-on servers. As modern applications increasingly run on serverless and edge platforms, the traditional model of provisioning and paying for constantly-running databases doesn't fit well. Upstash solves this by offering data services that are truly serverless: they scale automatically, can cost nothing when idle, and charge per request, making them a natural fit for serverless functions and edge deployments.

The platform's flagship offering is serverless Redis — a fast, in-memory data store ideal for caching, rate limiting, sessions, and real-time features — delivered in a way that works seamlessly with serverless and edge functions, with per-request pricing and global low-latency access. Upstash has expanded to include serverless Kafka for event streaming and a serverless vector database for AI applications, all following the same pay-per-use, low-maintenance philosophy. Its services are designed to be easy to integrate, globally distributed for low latency, and economical for the bursty, variable workloads that serverless applications typically have.

Upstash is used by developers building serverless and edge applications who need data services that match the serverless model — scaling automatically and costing little when idle. The value is the right data infrastructure for modern architectures: instead of paying for always-on databases that don't fit serverless workloads, developers get fast, globally-distributed data services with usage-based pricing that align perfectly with serverless functions and edge deployments. As serverless and edge computing become more prevalent, and as AI applications need vector storage, Upstash's serverless-first approach to data is increasingly valuable. For developers building on modern, serverless architectures, it offers data services purpose-built for exactly that world.
