Bottles

Bottles is an open-source GTK application that manages Wine prefixes as isolated, sandboxed "bottles," letting Linux users install and run Windows software and games without one shared, fragile Wine environment. Each bottle automatically handles installation of the right Wine or Proton runner and required Windows dependencies, and includes built-in snapshot support to save and roll back a bottle's state before making risky changes. For gaming, Bottles bundles tuning options like DXVK, esync, fsync, and shader caching, plus integrated MangoHud and Gamescope support, alongside a built-in task manager for Wine processes and an experimental installers database for one-click app setup. It is licensed under GPL-3.0 and distributed primarily as a Flatpak, which the developers recommend because it also sandboxes Bottles itself and provides an exclusive compatibility runtime.

Playnite

Playnite is a free and open-source video game library manager for Windows that consolidates installed and owned games from Steam, Epic Games Store, GOG, EA App, Ubisoft Connect, Battle.net, Xbox, and emulated titles into a single browsable collection. Instead of replacing each storefront's launcher, it detects and imports libraries from them and launches games through their original platform. The interface is fully themeable, from simple color tweaks to complete custom layouts, and a controller-friendly fullscreen mode is built in for couch or handheld use. Its plugin ecosystem, with dozens of community-built add-ons, extends metadata scraping, additional store integrations, and emulator auto-detection, and the project is developed with no telemetry, ads, or hidden costs.

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.
