universal-startfile
A cross-platform version of 'os.startfile' from the standard library.
Decision gist · record as of 2026-08-14
Yes. The package solves a genuine cross-platform gap in the standard library with zero dependencies, active maintenance, and a permissive license. It is stable despite its Alpha classifier and has been in use since 2022. Install it if you need to open files or URLs with system defaults in a portable way.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Low friction: pure Python wheel with no runtime dependencies.
- Actively maintained with recent commits; marked Alpha but has been stable since first release in 2022.

What it is and what it does
universal-startfile is a thin cross-platform wrapper that mimics the behavior of Python's os.startfile function (which only works on Windows) on macOS and Linux. It lets you open a file or URL by invoking the operating system's default handler—the same action as double-clicking a file or clicking a link in a browser. The package has no runtime dependencies and installs as a pure Python wheel, making it lightweight and portable.
You import a single function, startfile, and pass it a file path or URL. The package handles the platform-specific logic internally, delegating to the appropriate system command (xdg-open on Linux, open on macOS, os.startfile on Windows). It's useful in desktop automation, file management utilities, or any script that needs to hand off a resource to the user's preferred application without knowing which one that is.
Use it for
- Open a downloaded file in its default application from within a Python script or CLI tool.
- Launch a URL in the user's default browser without hardcoding browser names.
- Implement a cross-platform 'open with default app' feature in a desktop utility.
- Trigger file-manager or document-viewer actions from automation scripts on multiple OS platforms.
