cfenv
Python wrapper for Cloud Foundry environments
Decision gist · record as of 2026-08-14
No, unless you are maintaining a legacy Cloud Foundry application that already uses this package. The project is abandoned (last commit 2019-01-23), classified as Pre-Alpha, and has not been tested against modern Python versions. If you are starting a new Cloud Foundry project, investigate current Cloud Foundry Python tooling or parse VCAP_SERVICES directly; if you must use this, pin it and test thoroughly in your environment.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a Cloud Foundry environment with VCAP_SERVICES and VCAP_APPLICATION environment variables set; will not function meaningfully outside a deployed CF app.
- Low install friction with a single dependency (furl).
- However, the package is abandoned—last commit was 2019-01-23, over six years ago, and it is classified as Pre-Alpha.

What it is and what it does
py-cfenv is a lightweight wrapper around Cloud Foundry's environment variable conventions, designed to make it easier to read app metadata and service credentials in Python applications running on CF. It parses the VCAP_SERVICES and VCAP_APPLICATION JSON structures that Cloud Foundry injects into deployed apps, exposing them through a simple object interface so you can retrieve your app's name, port, and bound service credentials without manual JSON parsing.
The package depends only on furl for URL manipulation and installs with low friction. However, it has been abandoned since early 2019 and is marked Pre-Alpha; it was never intended for production use. Its classifiers list support only up to Python 3.5, and there is no indication of ongoing maintenance or compatibility with modern Python versions or Cloud Foundry API changes.
Use it for
- Extract app name and port from VCAP_APPLICATION in a Cloud Foundry-deployed Python app.
- Retrieve database connection credentials for a bound PostgreSQL or MySQL service by label.
- Build a service URL from parsed credentials (e.g., redis://user:pass@host:port).
- Simplify environment variable parsing in a legacy Cloud Foundry application still in production.
