A free, open-source proxy for PyPI and npm that delays brand-new package releases, blocks known malware, and verifies downloads.

Landing page captured for the 2026-10-03 issue.
For
Developers and small teams using PyPI or npm
Worth noticing
A local Docker trial binds the proxy to 127.0.0.1 and refuses known malware with HTTP 451.

Field notes

The homepage gives a runnable Docker command bound to localhost, then shows how to route pip, uv, and npm through its local endpoints. It says releases younger than a week are withheld and known-malware requests return HTTP 451; the broader description also says downloads are verified. Team deployment options include Docker Compose, Podman, and Kubernetes, while the homepage labels Python and JavaScript support as available today and broader coverage as future.
