You can run uvx --from workers-py pywrangler dev in any example project directory to run a local development server using Pywrangler, the CLI for Cloudflare Python Workers. This local development server is powered by workerd, the open-source Workers runtime.
Need to deploy your Worker to Cloudflare? Python Workers are in open beta and have a few limitations.
01-hello/— the most basic Python Worker02-binding/— shows how bindings work in Python Workers. Put a key into Workers KV, and then read it.03-fastapi/— demonstrates how to use the FastAPI package with Python Workers04-query-d1/- shows how to query D1 with Python Workers05-langchain/— demonstrates how to use the LangChain package with Python Workers. Currently broken.06-assets/— An example with an assets binding.07-durable-objects/— An example with storing state in a Durable Object.08-cron/— shows a simple cron job.09-workers-ai/makes a call Workers AI to run inference on Cloudflare's Global Network.10-workflows/— shows a durable Workflows example.11-opengraph/— shows how to use HTMLRewriter to generate OpenGraph images with Python Workers.12-image-gen/— shows how to use Pillow to generate images with Python Workers.13-js-api-pygments/— shows how to use Pygments to highlight code with Python Workers.14-websocket-stream-consumer/— shows how to use WebSocket to consume a stream of data with Python Workers.15-chatroom/- A real-time chatroom using WebSocket.
- You must add the
python_workerscompatibility flag to your Worker while Python Workers are in open beta.
