LunaBox

Open-source visual novel manager with automatic playtime tracking and AI habit analysis

60/100MonitorFreeFree

LunaBox nails the visual novel niche with reliable tracking and a genuinely fun AI twist, and the recent speed boost to its on-device model makes analysis both private and practical. Playnite handles multi-genre libraries better, but LunaBox is a free, open-source option worth serious consideration for anyone who lives and breathes VNs.

About LunaBox

FreeIntermediateNo APIDesktop · CLI

LunaBox is a lightweight, open-source visual novel manager that brings together library organization, automatic playtime tracking, and AI-powered habit analysis in one tool. It's built for collectors who maintain large VN libraries and want clear statistics plus a bit of automated insight. You can create custom categories, edit metadata flexibly, and import games in batches from local folders or migrate from Playnite, PotatoVN, or Vnite. Playtime tracking is automatic: LunaBox detects running game processes and records sessions, then turns that data into multi-dimensional charts. Cloud sync via S3 and OneDrive keeps your library and stats backed up, and CLI commands let you launch games or query your collection from the terminal. You can mark games as not started, in progress, or completed, and use rich search and filtering by keyword or classification to navigate even the largest libraries. The AI analysis is the signature feature: a built-in assistant digs into your play habits and generates humorous reports. Recent optimizations pushed local inference to 32.7 tokens per second when running DSV4 Flash 0731 on AMD Strix Halo hardware, making on-device analysis faster and more practical. The tool also includes plain-text export of your game lists. LunaBox is released under the AGPL v3 license, so it's free to use and modify, with a focus on privacy and community-driven development. It targets the visual novel niche specifically, which sets it apart from general-purpose game managers like Playnite or Steam that cover all genres. If your library is exclusively or primarily VNs, LunaBox gives you a tailored experience that broader tools can't match.

Behind the Verdict

If you're a visual novel collector, LunaBox is the rare tool that treats your niche as a first-class citizen. It doesn't try to be a jack-of-all-trades like Playnite; it goes deep on the things VN fans actually care about: automatic playtime tracking, flexible metadata, and a built-in AI that turns your play habits into reports with actual personality. The 32.7 tok/s local inference speed on AMD Strix Halo is a real win—it means the AI analysis can run on-device without sending your data anywhere. Where LunaBox shines is in library organization. Custom categories, batch import, and migration from Playnite, PotatoVN, and Vnite make switching over painless. The automatic process detection for time tracking is a set-and-forget feature; you don't have to remember to start or stop a timer. And if you live in the terminal, the CLI commands give you a way to launch games and query your collection without touching the GUI. The AI habit analysis is the differentiator, but it's also where expectations need to be managed. It's not a deep psychological study—it's a fun, humorous take on your play patterns. If you want serious data analytics, the multi-dimensional charts are there, but the AI reports are more about entertainment than insight. Compared to Playnite, LunaBox is deliberately narrower. Playnite covers every genre, integrates with stores, and has a huge plugin ecosystem—but that breadth can feel overwhelming when all you want is a clean VN library. LunaBox strips away the noise and gives you exactly what you need, no more. The cloud sync via S3 and OneDrive is a practical feature for backing up your library and stats, though it does assume you have your own storage. If you're not comfortable setting up S3 or linking OneDrive, you'll miss out on that safety net. We'd
