Edge compute platform running JavaScript, TypeScript, and WASM at 300+ locations worldwide with near-zero cold starts
What Is Cloudflare Workers?
Edge compute platform running JavaScript, TypeScript, and WASM at 300+ locations worldwide with near-zero cold starts It is supported by Rapidly growing ecosystem with KV storage, Durable Objects, R2, D1 database, Queues, and AI inference capabilities with Low to moderate — familiar JavaScript/TypeScript with Workers-specific APIs for KV, Durable Objects, and R2 storage.
How Cloudflare Workers Works
V8 isolate-based architecture executing code at the network edge without traditional container or VM overhead
Key Use Cases
- Edge API endpoints and middleware
- Request routing and transformation
- A/B testing and personalization at the edge
- Low-latency global applications
When to Use Cloudflare Workers
Cloudflare Workers is a strong choice when your project requires Edge API endpoints and middleware, Request routing and transformation, A/B testing and personalization at the edge. Cloudflare Workers delivers sub-millisecond cold starts with V8 isolates, global distribution across 300+ PoPs, but limited to 30s CPU time on free tier.
Strengths and Advantages
Limitations and Considerations
CPU time limits, no native Node.js API support, 128MB memory limit, and some npm packages are incompatible with the Workers runtime
