Cloudflare Announces General Availability of Python Support in Workers with Native Ecosystem Integrations
Cloudflare Workers now natively supports Python as a first-class language, allowing developers to directly interact with services like D1, R2, and Workers AI without JavaScript glue code.
Cloudflare has announced the general availability of Python support in its edge computing platform, Cloudflare Workers. Python is now treated as a first-class language alongside TypeScript, offering full support across the platform. This update enables developers to write pure Python code to interact directly with Cloudflare ecosystem resources such as D1 databases, R2 storage, Workers AI, and Durable Objects.

Comparison
| Aspect | Before / Alternative | After / This |
|---|---|---|
| Language runtime | JavaScript or TypeScript required, or Python with JS wrappers | Native Python compiled via Pyodide Wasm |
| Resource bindings | Required JavaScript glue code to access D1, R2, and Durable Objects | Direct native Python access to Cloudflare services |
| AI and orchestration | Limited integration paths for Python AI pipelines | Seamless integration with Workers AI, Hyperdrive, Queues, and Workflows |
Action Checklist
- Review Pyodide library compatibility for any existing Python dependencies Libraries relying on complex C extensions may have limited support in the WebAssembly environment.
- Measure cold start latency with the new Python runtime Wasm-based startup times may differ from traditional standard Python environments.
- Migrate existing JavaScript glue code in Workers to native Python bindings This simplifies repository structures and reduces boilerplate code for D1 or R2 integrations.
