platformdirs

platformdirs is a Python library for determining platform-specific system directories — user data, config, cache, logs, runtime, and more. It is the actively maintained community fork of the now-deprecated appdirs package, implementing the XDG Base Directory Spec on Linux, ~/Library conventions on macOS, and AppData on Windows, with additional Android support. Current version is 4.9.4 (released 2026-03-05); the project releases frequently, with multiple minor/patch releases per month during active development periods.
