Oslo Utility library
Decision gist · record as of 2026-08-14
Yes, if you are building or maintaining OpenStack services or applications that already depend on oslo libraries. The low install friction, active maintenance, permissive license, and broad Python version support make it a safe choice. If you are not in the OpenStack ecosystem and need only one or two of its utility categories, consider whether a smaller, single-purpose library would reduce your dependency footprint.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low install friction with a pure-wheel distribution.
- Active maintenance status and support for current Python versions (3.10–3.13) indicate ongoing care.

What it is and what it does
oslo.utils is a utility library from the OpenStack project that bundles common functions for encoding, exception handling, string manipulation, and time handling. It is designed to reduce boilerplate in OpenStack services and other Python applications that need these operations. The library depends on iso8601, oslo.i18n, netaddr, pyparsing, packaging, PyYAML, psutil, and pbr, making it suitable for applications already in the OpenStack ecosystem or those comfortable with these dependencies.
The package is actively maintained, supports Python 3.10 through 3.13, and carries an Apache-2.0 license. It installs with low friction as a pure wheel. With over 2 million monthly downloads and a position in the top 5000 PyPI packages, it is widely used in production systems. No known security vulnerabilities are recorded.
Use it for
- Standardize string encoding and decoding across OpenStack services or microservices.
- Parse and format timestamps consistently using built-in time handling utilities.
- Handle common exceptions with utility functions designed for distributed systems.
- Manipulate and validate network addresses using netaddr integration.
- Reduce code duplication in applications that need cross-cutting utility functions.
