TF2 Backpack Expander 🎒

English | فارسی

English

A Windows desktop app (built with Electron) that connects to your Steam account and Team Fortress 2's Game Coordinator, then lets you use Backpack Expander items with a single click to grow your backpack capacity — no manual crafting/using through the TF2 client needed.

✨ Features

🔐 Sign in with your Steam account (with Steam Guard support — email or mobile code)
💾 Optional "Remember me" — credentials are encrypted with your OS's native encryption (Windows DPAPI via Electron's safeStorage) and stored only on your machine
🎒 Detects Backpack Expanders in your backpack and uses them with one click
📊 Shows your current backpack slots and account type (Free / Premium), live-updating as expanders are used
📦 Full inventory tab — browse, search, and delete items
🎮 Join/Leave TF2 toggle, so the app can talk to the Game Coordinator without you having to launch the game
🛒 Built-in "Need backpack?" helper on the Backpack tab that opens the Steam Store purchase page for Backpack Expanders, with a quantity field
🧳 Custom app/taskbar icon

Sign in with your Steam account inside the app.

⚠️ Windows SmartScreen or your antivirus may flag the .exe because it's not code-signed. This is expected for an open-source, unsigned build — you can inspect the source code in this repo yourself before running it.

Run build.bat to produce a portable .exe — the output will be in the release/ folder.
