Backlog Zero v1.3.0

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 brings your games from Steam, Xbox, GOG, Epic, Amazon Luna, and other sources into one place, flags duplicates across platforms, and helps you understand the library you already have.

It is built for the kind of player whose collection has grown across years, storefronts, bundles, subscriptions, giveaways, wishlists, and good intentions.

Backlog Zero is not a launcher replacement. It is a record keeper for your gaming life: what you own, where you own it, what you keep meaning to play, what you keep rebuying, and what your habits say about the way you actually play.

What's included:

• Unified library tracking across Steam, Xbox, GOG, Epic Games, Amazon Luna, and Game Pass catalog data
• Duplicate detection across platforms
• Library Health tools for covers, missing details, duplicates, hidden games, and cleanup signals
• Add-on and DLC handling so extras do not inflate your main library count
• Wishlist tracking with target prices, deal alerts, and price history context
• Free games discovery across supported storefronts
• Playtime and session tracking, including automatic Steam session tracking
• Manual session logging for platforms that do not expose playtime reliably
• Backlog goals and progress tracking
• Decision tools to help you choose what to play next
• -dentity Dossier, a monthly snapshot of your gaming behavior and collection habits
• Friends library comparison
• Full JSON backup, export, and restore tools
• Dark, Light, and Accessible themes

Backlog Zero v1.3 improves library trust with cleaner sync behavior, better GOG and Heroic handling, add-on/DLC cleanup, wishlist improvements, and a one-time recalibration tool for older libraries.

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