Cloudflare Workers
Deploy serverless functions globally in seconds·workers.cloudflare.com
Cloudflare Workers is a serverless functions platform that lets developers deploy code written in JavaScript, TypeScript, Python, or Rust to Cloudflare's global network of 330+ cities. It scales automatically from zero to millions of requests with no cold starts and infinite concurrency, charging only for CPU execution time. Workers can be bound to other Cloudflare services like D1, KV, R2, Queues, Workflows, Durable Objects and Workers AI to build full-stack applications, APIs, and background jobs.
