Upstash Has a Free Serverless Redis: Zero-Config Redis and Kafka for Edge and Serverless Functions

You need Redis for caching, rate limiting, or session storage. Traditional Redis requires a server, persistent connection, and doesn't work in serverless environments where connections are ephemeral. What if Redis worked over HTTP — no persistent connections, no server management, pay-per-request pricing? That's Upstash. Serverless Redis and Kafka designed for edge computing and serverless functions.
