Gameyfin

Gameyfin

Gameyfin organizes your video game collection into a searchable web library with automatic scanning, metadata fetching, downloads, sharing, and optional SSO integration.

Gameyfin is an open source, web-based application for organizing and browsing a video game collection. It scans your game folders, enriches entries with metadata and cover art, and presents everything in a fast, easy-to-navigate library you can access from any modern browser.

Key Features

  • Automatically scans and indexes game libraries from configured folders
  • Fetches metadata and cover images to enrich your catalog
  • Web UI for browsing your collection and downloading game files
  • Library sharing for friends and family
  • LAN-friendly caching to keep browsing fast on local networks (videos may still be fetched remotely)
  • Theme support, including colorblind-friendly options
  • Plugin system for extending functionality
  • Optional SSO integration via OAuth2 / OpenID Connect

Use Cases

  • Create a centralized catalog for a large local ROM/game archive
  • Share a curated game library with family or a small community
  • Run a lightweight, browser-accessible game library for a homelab

Limitations and Considerations

  • Metadata quality and matching depend on external metadata sources and file naming consistency
  • Persistence is based on an embedded H2 database by default, which may be less suitable for very large deployments

Gameyfin is a good fit for users who want a Jellyfin-like experience for game collections, with a clean UI, automatic library organization, and extensibility. It can run in a container or on any JVM-capable system and is designed to be simple and fast.

RetroAssembly

RetroAssembly

A web application that organizes and runs retro game ROMs in the browser with cloud saves, automatic box art, controller support and multi-platform emulation.

RetroAssembly is a browser-first application that combines a retro game library frontend with in-browser emulation. It presents a cabinet-like interface to browse, launch and play ROMs across many classic platforms directly in a web tab.

Key Features

  • Browser-based gameplay: play supported retro consoles (NES, SNES, Genesis, Game Boy, GBA, arcade, Atari and more) without installing local emulators.
  • Multi-emulator support: uses a JS emulation layer to select appropriate engines per platform and run games in the browser.
  • Cloud sync and save states: save progress and synchronize states across devices so you can resume play elsewhere.
  • Automatic box art retrieval: scans uploaded ROMs and fetches cover/box art to present an organized visual library.
  • Gamepad and keyboard-first navigation: spatial navigation and full gamepad controls plus an on-screen virtual controller for devices without physical pads.
  • Rewind and state features: some emulators expose rewind and instant save/restore controls for improved playability.
  • Hosted demo and official hosted option: live demo library of free/retrobrew titles for evaluation and an official hosted service for quick onboarding.
  • Account sign-in (Google OAuth) for personal libraries and synchronization.

Use Cases

  • Keep a personal, searchable catalog of legitimately owned retro ROMs and access them from any device via the browser.
  • Rapidly demo and try homebrew/retrobrew titles at events, streams or when testing emulator configurations.
  • Provide an accessible front-end for enthusiasts who want a visually rich, gamepad-friendly way to browse and play classics without desktop installs.

Limitations and Considerations

  • Legal responsibility for ROM ownership rests with users; the project provides emulation and library tooling but does not supply commercial ROMs.
  • Browser-based emulation performance and compatibility vary by platform and device; some systems or large ROMs may be less performant on low-power clients.
  • Hosted synchronization depends on the official service or a user-run instance; offline play is supported but cloud features require an account.

RetroAssembly is focused on ease of access, visual presentation and cross-device continuity for retro game collections. It balances multiple emulator engines with a unified, gamepad-friendly interface to make classic games easy to browse and play from the browser.

LANCommander is an open-source digital game platform designed for local networks and LAN parties. It provides a self-hostable server and a dedicated launcher to manage, distribute and launch game archives without relying on internet-hosted assets.

Key Features

  • Centralized game management: upload and organize game archives, metadata, covers and media
  • Built-in distribution: HTTP(S) download endpoints for clients and a dedicated launcher for easy client setup
  • Dedicated server management and basic chat for coordinating play sessions
  • Local "cloud" user saves and user registration/user management features
  • IPX beacon and UDP support for emulator/dosbox-style discovery
  • Lightweight SQLite database backend for simple setup and portability
  • Official Docker image with optional SteamCMD and WINE support for automated server builds
  • LANCommander.SDK (.NET) for integrating or extending client applications

Use Cases

  • Running a LAN party or local gaming event where internet access is restricted or unavailable
  • Hosting a private game library and distributing installers/patches to a closed network of clients
  • Managing dedicated game servers and coordinating players with integrated chat and discovery

Limitations and Considerations

  • The official launcher has been primarily tested on Windows; other OS builds may have varying compatibility
  • The Docker image runs the Linux build and some server/management features may be limited in that environment
  • LANCommander does not include games; administrators must provide portable/DRM-free game archives
  • Uses SQLite by default, which simplifies setup but can limit scalability for very large deployments

LANCommander is focused on reliable local distribution and simple administration for LAN-centric gaming. It is suited to event hosts and small networks that need an offline-capable game distribution and launcher system.
