Yes, if you maintain a setuptools-based Python project with version control and want to eliminate manual version-string management. The tool is permissively licensed, has no runtime dependencies, and is actively maintained. However, the latest PyPI release is from 2021-04-01; verify current compatibility with your Python version and build toolchain before adopting.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a setuptools-based project with version control initialized; configuration via pyproject.toml or setup.cfg required.
- Low install friction with no runtime dependencies.
- Actively maintained with recent commits (last commit 2026-06-01) and 1092 repository stars, though the latest PyPI release dates to 2021-04-01.

What it is and what it does
versioneer-518 is a tool that automatically manages version strings in Python projects by querying your version-control system at build and import time. Instead of manually updating a version string before each release, you tag your repository and the tool derives the version from that tag, generating version strings that comply with PEP 440 by default. It works by injecting a `_version.py` module into your source tree that dynamically queries the VCS for tag information, and a top-level `versioneer.py` that integrates with setuptools to compute versions during builds.
The tool supports two installation modes: vendored mode (copies the tool into your repository) and build-time dependency mode (treats it as a build requirement). It provides multiple pieces of version information—condensed version string, full revision ID, commit date, and dirty-tree status—allowing projects to embed rich version metadata. It is designed for setuptools-based projects and requires configuration in either `pyproject.toml` or `setup.cfg`. It has no runtime dependencies and installs as a pure Python wheel.
Use it for
- Eliminate manual version-string updates in setup.py or pyproject.toml by deriving versions automatically from version-control tags.
- Generate version strings that reflect both release tags and development commits without manual intervention.
- Embed version information in module `__version__` attributes and tarball names automatically.
- Provide developers and bug reporters with full revision IDs and commit dates to reconstruct exact code states.
- Simplify release workflows by making version management a pure version-control operation—tag, build, release.
