Read settings from config files
Decision gist · record as of 2026-08-14
Yes, if you need to read and validate user configuration files in a Python package or CLI tool. The low install friction, permissive license, and straightforward API make it practical. However, the aging maintenance status (309 days since last release) means you should verify the package still meets your needs and be prepared to maintain a fork if critical issues arise.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Low install friction with a pure-Python wheel and five lightweight runtime dependencies.
- Maintenance status is aging—last release was 309 days ago—so expect slower response to issues.

What it is and what it does
Maison is a configuration file reader designed for Python packages and command-line tools. It loads settings from files like pyproject.toml or .ini files in a user's directory, with optional validation and built-in caching. The package exposes a UserConfig class that retrieves configuration values by package name, making it straightforward to let users customize tool behavior through standard config files.
The library supports multiple config file types and optional merging of settings across files. It is fully typed and tested. Runtime dependencies are loguru, platformdirs, tomli, typer, and typing-extensions. The package requires Python 3.9 or later.
Use it for
- Load tool settings from pyproject.toml so users can configure behavior without command-line flags
- Read and validate configuration from .ini or other config files with optional validation
- Cache config file contents to avoid repeated disk reads in long-running applications
- Merge settings from multiple config files to support layered configuration strategies
- Build CLI tools that respect user preferences stored in standard config locations
