Backlog Zero

Backlog Zero started as a question: how many times do I own the same game?

A Steam sale here, a free Epic claim there, a third-party key bought and forgotten — and suddenly you're about to buy a game you already own twice. That frustration turned into an app.

Backlog Zero is a personal game library manager for Mac and Windows. It pulls your games from Steam, Xbox, GOG, Epic, and Amazon Luna into one place, flags duplicates across platforms, and gives you a real picture of what you actually own.

Backlog Zero isn't a spreadsheet with a UI. It's a full picture of your gaming life — from your duplicate count to your gamer archetype — built entirely around your data, on your machine, going nowhere.

What's included:

• Library management across Steam, Xbox, GOG, Epic Games, and Amazon Luna
• Duplicate detection across all platforms
• Statistics dashboard with Library Health
• Automatic Steam session tracking, manual logging for all other platforms
• Backlog goals and progress tracking
• Identity Dossier with 10 gamer archetype cards
• Habits dashboard
• Wishlist with price tracking
• Free games aggregator
• Backlog Picker
• Friends library comparison
• Full JSON export and import
• Dark, Light, and Accessible themes

No account required. No cloud. No telemetry. Your data stays on your machine.

Backlog Zero is free. If it saves you from buying a game you already own, maybe it's worth a coffee — but it's entirely optional.
