About
Playnite is a free, open-source video game library manager for PC that aggregates games from multiple platforms—Steam, Epic, GOG, Origin, and others—into a single interface. It supports console emulation, custom themes, plugins, playtime tracking, and a fullscreen controller-friendly mode. All library data is stored locally with no remote servers involved.
Problem
Gamers with libraries across many stores and emulators have no single place to browse, launch, and track all their games.
For
PC gamers with games spread across multiple storefronts and platforms
How it works
Playnite links to existing game library accounts and local installations, aggregates them into one interface, and extends functionality via plugins and scripts.
