workers.dev
workers.dev is a domain owned by Cloudflare that provides free subdomains for applications deployed on Cloudflare Workers, their serverless computing platform.
Cloudflare Workers Platform
Cloudflare Workers allows developers to deploy serverless code that runs globally across Cloudflare's edge network in 330+ cities worldwide. Key capabilities include:
- Serverless Compute - JavaScript, TypeScript, Python, and Rust execution with minimal cold starts
- Storage Solutions - R2 object storage, Workers KV (key-value), and Durable Objects for stateful applications
- AI Infrastructure - Built-in AI inference, AI Gateway, and agent capabilities
- Global Distribution - Code executes within 50ms of 95% of the world's population
The workers.dev Domain
When developers deploy a Cloudflare Worker without a custom domain, they receive a free subdomain under workers.dev (e.g., myapp.username.workers.dev). This makes it easy to:
- Quickly deploy and test applications without purchasing a domain
- Share prototypes and demos
- Run production workloads on Cloudflare's infrastructure
The platform is popular for building APIs, full-stack web applications, real-time multiplayer experiences, and AI-powered services with automatic scaling and pay-per-use pricing.
