What it is and what it does
workers-runtime-sdk is a Python SDK that provides runtime bindings and APIs for applications deployed on Cloudflare Workers. It enables developers to write serverless Python code that runs on Cloudflare's edge network, handling HTTP requests and responses through a familiar Python interface.
The SDK is part of a larger monorepo that includes CLI tools and Django integrations for Cloudflare services. It has no external runtime dependencies, making it lightweight to install. The package is actively maintained with recent releases and supports current Python versions (3.11+).
Use it for
- Build HTTP handlers for serverless functions running on Cloudflare's edge network
- Create request/response middleware for Cloudflare Workers using Python
- Integrate Python applications with Cloudflare services like D1, Durable Objects, and R2
- Deploy Python-based APIs and microservices without managing servers
