Lutris

Lutris is an open-source video game preservation platform for Linux that brings together Wine, Proton, and dozens of emulators, including MAME, Dolphin, RetroArch, and ScummVM, behind a single launcher interface. It can sync game libraries from Steam, GOG, Epic Games Store, and Humble Bundle through an optional lutris.net account, and it uses community-maintained JSON and YAML install scripts to automate setup for games and emulators that would otherwise require manual configuration. Beyond installation, Lutris lets users configure per-game runners and Wine versions, apply Vulkan-based performance tuning, and manage everything from a command-line interface as well as the GUI. It is entirely free and licensed under GPL-3.0, with an optional Patreon supporting ongoing development. As a Linux-only tool, it is commonly used both to play Windows games without a native Linux release and to preserve older titles through emulation.

Hydra Launcher

Hydra Launcher is a free, open-source gaming platform built to be a single tool for managing, downloading, and launching a PC game library. It centralizes game discovery and library organization in one place, adds a built-in downloader client, and lets players track achievements, save progress to the cloud through Hydra Cloud, and see what friends are currently playing through user profiles. The project is fully open source under the MIT license and built with Electron, React, TypeScript, Python, and Rust, with active development on GitHub and builds available for Windows, macOS, and Linux. Community-made themes can be downloaded to customize the launcher's look, and a recommendation system helps surface new games to try.

ES-DE

ES-DE (EmulationStation Desktop Edition) is a frontend for organizing and launching games across a large, multi-platform collection, preconfigured to work with more than 150 game systems including emulators, native game engines, and game managers. Rather than hunting through folders, users get a themeable, controller-navigable interface with a built-in scraper that pulls box art, descriptions, and other metadata automatically. The desktop releases for Windows, macOS, and Linux are fully open source and free, while a separate Android release is a paid app distributed through Patreon and app stores. ES-DE is actively maintained, with frequent releases, an extensive theme library, and detailed documentation backed by an active Discord community.

Heroic Games Launcher

Heroic Games Launcher is a free, open-source desktop app that lets PC and Steam Deck players manage and launch their Epic Games Store, GOG, and Amazon Prime Gaming libraries from a single interface, without needing the official Epic or Amazon clients running in the background. Built by a community of volunteer developers under a GPLv3 license, it bundles Wine and Proton compatibility layers so Linux and Steam Deck users can run Windows-only games, adds a download queue with live speed stats, custom artwork, and a console-style mode for TV setups, and ships with no ads, telemetry opt-outs, and no data resale.
