workerd-bin
An unofficial redistribution of Cloudflare workerd binaries as Python wheels, so workerd can be installed anywhere pip can reach PyPI.
The package version matches the upstream workerd release it contains.
Usage
pip install workerd-bin
workerd serve config.capnp
Or run it as a module (python -m workerd_bin), or locate the binary from Python:
from workerd_bin import find_workerd_bin
Supported platforms
- Linux x86_64 and aarch64 (glibc 2.35 or later)
- macOS 13.5 or later, x86_64 and arm64
Building
./scripts/build.sh
This builds one wheel per platform into dist/. There is deliberately no sdist: building one on an unsupported platform would install a binary that can't run there. Each wheel downloads the matching binary from the GitHub release named by version in pyproject.toml and checks it against the SHA-256 digest GitHub publishes for that asset. Set GITHUB_TOKEN if you hit API rate limits.
Releasing
Change version in pyproject.toml, commit, then push a matching tag (e.g. v1.20261023.1). GitHub Actions builds the wheels, smoke-tests them, and publishes to TestPyPI then PyPI using trusted publishing.
To release a packaging fix without changing workerd, append a post-release suffix (e.g. 1.20261023.1.post1).
