Backlog Zero

Backlog Zero is a desktop game-library manager for players tracking collections spread across several services. It is best for people who want to organize a backlog privately on a computer; the main trade-off is that some imports and companion features depend on outside services.

Overview

Backlog Zero brings ownership, play status, cover art, metadata, tags, and duplicate detection into one library. That makes it a practical fit for players who have accumulated games across storefronts and need to see what they own before buying or deciding what to play. Its emphasis is personal organization, not a shared collection.

Key features

Library imports cover Steam, Xbox, GOG, Epic Games, and Amazon Luna, with the FAQ also mentioning the PC Game Pass catalog. Xbox imports have a meaningful gap: they use achievement history, so a game that has never been launched will not appear automatically and must be added by hand. Some connections also require third-party services or credentials, including Steam API access, GOG Galaxy, Heroic, OpenXBL, and Twitch developer credentials for IGDB cover art. That flexibility broadens the app’s reach, but setup is less self-contained than a single-account library.

Session logging, backlog goals, completion history, statistics, and a Habits dashboard help turn a catalogue into a record of play. The Identity Dossier assigns one of ten gamer archetypes; it is a lighter, personality-oriented extra rather than a core tracking tool.

The Wishlist tracks prices through gg.deals and offers deal signals and alerts, while free-game listings collect Epic and Prime Gaming giveaways. These features can help surface opportunities, but price checking, cover-art fetching, and platform sync need an internet connection. Library data is stored locally and core library use works offline.

A mobile companion supports library browsing, session logging, the Backlog Picker, goals, and recent history over local Wi-Fi, localhost, or a private VPN. This extends access without making the product a conventional cloud-synced mobile service. The app can export libraries as JSON or CSV; the FAQ recommends a JSON backup before reinstalling.

The privacy policy says Backlog Zero has no analytics, crash reporting, telemetry, account system, or Backlog Zero server, and does not collect or transmit personal data. That local-first approach will appeal to privacy-conscious players, though it also means users should take responsibility for exporting backups.

Pricing

Free (pay what you want — including nothing): free. All features are included, with no tiers and no account requirement. For a personal library tool, that removes the usual trade-off between a free cap and paid tracking features. It suits both casual organizers and players who want imports, playtime tracking, and exports without a subscription; optional payment is not required for the full feature set.

Platforms

The desktop app is available for macOS and Windows. The mobile companion offers browsing and selected tracking tools, but it connects over local Wi-Fi, localhost, or a private VPN rather than providing an independently described cloud service.

Who it's for

Choose Backlog Zero if you own games across multiple services, want to spot duplicates, and prefer a local library with backlog goals and play history. It is less suitable if you need Xbox imports to capture every unplayed purchase automatically, want all integrations to work without third-party setup, or expect a full mobile-first experience.

Pros and cons

• Pro: All features are included at no cost, with no account or tier restrictions.
• Pro: Local storage, offline library access, and no personal-data collection or transmission make privacy a central strength.
• Pro: Imports, duplicate detection, backlog tracking, deal signals, and giveaway listings cover more of the game-collection workflow than a basic owned-games list.
• Con: Xbox imports miss games without achievement history, requiring manual additions for unlaunched titles.
• Con: Several integrations depend on other services or credentials, and internet access is needed for sync, cover art, and price checks.
• Con: The mobile companion is limited to local Wi-Fi, localhost, or private VPN connections.

Verdict

Backlog Zero is a strong choice for desktop players who want a private, feature-rich way to reconcile libraries and make progress on a backlog without paying. Its local-first design and all-features-free plan are compelling; look elsewhere if you need automatic Xbox coverage for unplayed games, frictionless integrations, or a cloud-oriented mobile app.
