whispy-client 1.1.3

Stream Python packages at runtime — the PyPI CDN client

🌀 Whispy Client

Import Python packages at runtime with a zero-dependency client. Keep your scripts clean, your environments disposable, and your setup friction low.

The client lives in the Whispy repository, with the implementation in client/whispy_client and the server entrypoint in server/app.py. It downloads a bundle from a Whispy server, extracts it to a temporary directory, and imports the requested module at runtime.

When to Use It

• Throwaway scripts that need requests, numpy, or beautifulsoup4 without a setup step.
• Short-lived jobs where you want packages to vanish when the process exits.
• Pinned runtime experiments where one exact version matters.
• Self-hosted setups that point at your own server from the main repo.

Quick Examples

from whispy_client import remote, configure

configure(verbose=True)

requests = remote("requests")
numpy = remote("numpy==1.26.4")
bs4 = remote("beautifulsoup4", module="bs4", deps=True)

# Common import name mismatches
bs4 = remote("beautifulsoup4", module="bs4")
PIL = remote("pillow", module="PIL")
yaml = remote("pyyaml", module="yaml")
dateutil = remote("python-dateutil", module="dateutil")
cv2 = remote("opencv-python", module="cv2")

Install

pip install whispy-client

For local development from this repo:

cd client
pip install -e .

API

remote(package, *, module=None, version=None, deps=False, host=None)

package can be a bare PyPI distribution name or an exact pin such as requests==2.31.0. If the import name differs from the distribution name, pass module=....

deps=True asks the server to include install-time dependencies as well. That behavior is best-effort and does not perform full dependency conflict resolution.

Param	Description
package	PyPI distribution name, optionally with ==version
module	Import name if different from the package name
version	Explicit version override, if you do not want to embed it in package
deps	Fetch install-time dependencies as well
host	Per-call Whispy server override

configure(*, host=None, deps=None, verbose=None)

Sets process-wide defaults. The default host comes from WHISPY_HOST, falling back to https://cdn.whispycdn.dev.

Param	Description
host	Default Whispy server URL
deps	Default dependency-fetching behavior
verbose	Print progress messages while fetching and importing
