trove-classifiers is the authoritative registry of PyPI classifiers—the standardized taxonomy strings that categorize Python packages by development status, intended audience, license, framework, and other metadata. It ships as a simple data package with two main objects: a set of all valid classifiers for membership testing, and a dictionary mapping deprecated classifiers to their modern replacements.
You use it to validate classifier strings before uploading to PyPI, to programmatically check whether a classifier is current or obsolete, and to discover the correct replacement when you encounter a deprecated one. It can also be invoked as a command-line tool to list or search classifiers. With no external dependencies and active maintenance, it serves as a lightweight reference layer for any tool or workflow that needs to work with PyPI metadata.
Use it for
- Validate classifiers in setup.py or pyproject.toml before publishing to PyPI.
- Check if a classifier string is deprecated and retrieve its modern replacement.
- Build tooling that auto-suggests or corrects classifier choices during package setup.
- Query the canonical classifier set programmatically in CI/CD pipelines.
- Search or filter classifiers by keyword from the command line.
