Cloudflare Workers

Cloudflare Workers is a serverless execution environment that runs on Cloudflare's global network of 330+ data centers. Unlike traditional serverless platforms that deploy to specific regions, Workers runs your code in every location simultaneously, delivering sub-50ms response times to 95% of the Internet-connected population.

Built on the V8 JavaScript engine (the same engine that powers Chrome), Workers supports JavaScript, TypeScript, Python, Rust, and more, making it one of the most versatile serverless platforms available. With minimal cold starts and instant global deployment, Workers has become the platform of choice for developers building high-performance edge applications.

Lightning-Fast Edge Computing

Workers executes at Cloudflare's edge, meaning your code runs as close as possible to your users. This results in dramatically lower latency compared to centralized cloud functions:

• Sub-10ms cold starts – Nearly instant function invocation
• Zero-region deployment – Code runs in 330+ cities automatically
• 449 Tbps network capacity – Handles 81M+ HTTP requests per second
• Smart request routing – Automatically routes to optimal location
• No infrastructure management – Deploy with one command

Revolutionary Pricing Model

Cloudflare charges only for CPU time, not wall time. This means you never pay for idle time waiting for APIs, databases, or AI models. While your code waits for external responses, the clock stops:

• Free tier: 100,000 requests/day forever, no credit card required
• Paid: $0.30 per million requests + $0.02 per million CPU milliseconds
• No egress fees – Unlimited bandwidth included
• No surprise bills – Predictable, transparent pricing

Complete Developer Platform

Workers isn't just functions—it's a full application platform:

• Workers KV – Ultra-low latency key-value storage across 330+ locations
• Durable Objects – Stateful serverless with WebSocket support and strong consistency
• R2 Storage – Zero-egress object storage compatible with S3
• D1 Database – SQLite at the edge with built-in replication
• Queues – Reliable message queuing for background jobs
• Cron Triggers – Scheduled function execution
• Workers AI – Run AI models at the edge (25 requests/day free)
