Cloudflare takes Python Workers to general availability

Cloudflare announced on September 21, 2026 that Python Workers are now generally available, after months in an experimental release. Python becomes a first-class language on the Cloudflare Workers platform, on par with JavaScript, with native interoperability that removes the type-conversion glue code developers previously had to write.

#What changed since the beta

During the experimental phase, sending a plain Python dictionary to a Cloudflare Queue required explicit conversion code between Python objects and their underlying JavaScript representation. Cloudflare says it has now encapsulated the entire conversion process inside the runtime, so Python objects can be worked with directly, with no glue code required.

#Web frameworks running natively

FastAPI, Django and Flask now run natively on Workers through WSGI and ASGI connectors. An existing Python project built on any of these frameworks can be deployed on Cloudflare’s infrastructure without a rewrite to JavaScript, which lowers the barrier for teams already invested in Python.

#Database access through Hyperdrive

PostgreSQL and MySQL connectivity, previously unavailable because of WebAssembly’s socket limitations, is now reachable through Hyperdrive. This was one of the main blockers developers reported during the beta: a Python Worker could not easily talk to a standard relational database.

On the AI side, the OpenAI and LangChain libraries, along with the MCP protocol, work directly with Workers AI. A project that already exposes a server compliant with the MCP specification can therefore be hosted on Workers without switching languages.

#A minimal Python Worker example

A generally-available Python Worker is now declared with a minimal wrangler.toml configuration and a standard entry point:

from workers import WorkerEntrypoint, Response

class Default(WorkerEntrypoint):
    async def fetch(self, request):
        db = self.env.HYPERDRIVE
        return Response("Python Worker in production")

Python is now a first-class language on Cloudflare’s developer platform, on par with JavaScript.

#What it means for teams already on Cloudflare

For a team already running part of its application infrastructure on Cloudflare, the general availability of Python Workers opens the door to migrating an existing Python service without a full rewrite, while keeping the usual command-line workflow already built around Wrangler.

#Key takeaways

Cloudflare has taken Python Workers out of experimental status and is positioning them as a credible alternative to JavaScript on its serverless platform, with native support for FastAPI, Django and Flask, plus relational database access through Hyperdrive. The main point to watch remains the still-partial coverage of native Python extensions under WebAssembly.
