msedgedriver 0.1.0

Automated Microsoft Edge WebDriver manager for Selenium

msedgedriver

Automated Microsoft Edge WebDriver management for Python.

Stop manually checking your Edge browser version and downloading the matching WebDriver. msedgedriver automatically detects your local Microsoft Edge version, fetches the exact matching driver from Microsoft's official servers, caches it under ~/.msedgedriver/, and returns its path so your Selenium scripts can run seamlessly — on Windows, macOS, and Linux.

Features

• Zero-Config Automation: Auto-detects your Edge version (Windows Registry / macOS plist / Linux binary).
• Cross-Platform: Windows (win64), macOS Intel (mac64), macOS Apple Silicon (mac64 M1/ARM64), Linux (linux64).
• Returns Driver Path: install() returns the absolute path to msedgedriver.exe — pass it straight to Selenium's Service().
• Smart Caching: Downloads only when your browser version changes; subsequent calls are instant.
• Version Pinning: Pin a specific driver version with install(version="125.0.2535.51").
• Custom Install Path: Override the cache directory with install(install_path="/my/dir").
• Quiet Mode: Suppress all output with install(quiet=True).
• Proper Error Handling: Raises MsEdgeDriverException instead of silently swallowing errors.
• Logging Support: Uses Python's logging module — integrate with your own log config.

Installation

pip install msedgedriver

Quick Start

import msedgedriver
from selenium import webdriver
from selenium.webdriver.edge.service import Service

# Auto-detects Edge version, downloads driver if needed, returns path
path = msedgedriver.install()

driver = webdriver.Edge(service=Service(path))
driver.get("https://github.com")
print(driver.title)
driver.quit()

Full API Reference

msedgedriver.install(version=None, install_path=None, quiet=False) -> str

Downloads and caches the msedgedriver binary. Returns its absolute path.

# Auto-detect version (most common)
path = msedgedriver.install()

# Pin a specific version
path = msedgedriver.install(version="125.0.2535.51")

# Custom cache directory
path = msedgedriver.install(install_path="C:/my/drivers")

# Silent mode (no log output)
path = msedgedriver.install(quiet=True)

msedgedriver.get_edge_version() -> str

Returns the installed Microsoft Edge version string.

ver = msedgedriver.get_edge_version()
print(ver)  # e.g. "148.0.3967.96"

msedgedriver.get_driver_path(version=None, install_path=None) -> str | None

Returns the path to a cached driver without downloading. Returns None if not cached.

path = msedgedriver.get_driver_path()
if path:
    print(f"Already cached at: {path}")

msedgedriver.cleanup(install_path=None) -> None

Removes all cached driver versions except the currently installed Edge version.

msedgedriver.cleanup()

msedgedriver.MsEdgeDriverException

Exception raised when version detection or download fails.

try:
    path = msedgedriver.install()
except msedgedriver.MsEdgeDriverException as e:
    print(f"Driver setup failed: {e}")

Enable Logging

import logging
logging.basicConfig(level=logging.INFO)

import msedgedriver
msedgedriver.install()
# INFO  msedgedriver: Detected Edge version: 148.0.3967.96
# INFO  msedgedriver: Driver already up-to-date: C:\Users\You\.msedgedriver\148.0.3967.96\msedgedriver.exe

System Requirements

• Python: 3.8 or newer
• OS: Windows, macOS, or Linux
• Browser: Microsoft Edge must be installed

Version Detection by Platform

Platform	Method
Windows	Windows Registry (HKCU\SOFTWARE\Microsoft\Edge\BLBeacon)
macOS	defaults read /Applications/Microsoft Edge.app/Contents/Info.plist
Linux	microsoft-edge --version (tries stable, beta, dev channels)
