steam-client 6.0.0

Steam client library for Python

Steam Client

A Python library for interacting with a locally installed Steam client — enumerate your game library/non-steam games, read game metadata and artwork paths, and send Steam URI commands.

---

Installation

Requires Python 3.11+.

pip install steam-client

Or install from source:

pip install -e .

---

Quickstart

from steam_client.steam import Steam

steam = Steam()  # Uses default path: C:\Program Files (x86)\Steam

# On Windows, auto-detect path from registry:
from steam_client.utils import steam_from_registry
steam = steam_from_registry()

---

Common Operations

List all installed games

for game in steam.library.games():
    print(game.appid, game.name)

Find a game

game = steam.library.game_by_id("440")       # by app ID
game = steam.library.game_by_name("Portal 2") # by name (case-insensitive)

Artwork paths

game.header   # Path to header image    (460×215 jpg)
game.grid     # Path to grid image      (600×900 jpg)
game.hero     # Path to hero image
game.icon     # Path to icon file, or None

Launch and manage games via Steam URI commands

from steam_client import commands
from steam_client.commands import SteamWindow

commands.run_game_id("440")               # Launch a game
commands.store("440")                     # Open store page
commands.install("440")                   # Prompt install
commands.uninstall("440")                 # Prompt uninstall
commands.open_window(SteamWindow.FRIENDS) # Open a Steam window
commands.open_url("https://store.steampowered.com")

Or launch a game directly from a Game object:

game.run()

Users and shortcuts

for user in steam.users:
    print(user.user.data.PersonaName)

for shortcut in steam.library.shortcuts():
    print(shortcut.name)

If Steam is not installed at the given path, calls that read Steam data raise steam_client.SteamNotFoundError.

Platform Notes

Platform	Path	Registry helper
Windows	C:\Program Files (x86)\Steam (default)	steam_from_registry()
Linux	Pass yours, e.g. ~/.local/share/Steam	Not available

Pass a custom path to override the default:

steam = Steam("/custom/steam/path")

Requires read access to local Steam config files (libraryfolders.vdf, shortcuts.vdf, appmanifest files).
