Discover Open Source Games

What Are Open Source Games?

Open source games are video games whose source code is publicly available for anyone to view, modify, and distribute. Unlike proprietary games, these projects invite players and developers to learn from real game codebases, contribute improvements, and create custom modifications. The open gaming movement has grown dramatically, with over 630 million repositories on GitHub and more than 100 million developers collaborating worldwide.

Why Play Open Source Games?

• Completely Free: No microtransactions, no loot boxes, no hidden costs. Every game in our directory is free to download and play.
• Learn Game Development: Study actual production code from real games. See how professionals implement game mechanics, graphics, networking, and AI.
• Community-Driven: Active communities continuously improve games, fix bugs, and add new features based on player feedback.
• Transparent & Trustworthy: Open code means no spyware, no DRM restrictions, and full control over your gaming experience.
• Cross-Platform: Most open source games work on Windows, macOS, and Linux, giving you freedom from platform lock-in.

The Open Source Gaming Ecosystem

The global gaming market is projected to exceed $300 billion by 2027, and open source software plays an increasingly important role. GitHub hosts hundreds of thousands of game development repositories, from indie passion projects to commercial-quality engines. Open source game engines like Godot have democratized game development, while libraries like SDL, OpenGL, and Vulkan power countless commercial and indie games alike.

By exploring open source games, you're not just playing—you're joining a global community of developers, artists, designers, and players who believe in the power of open collaboration. Whether you're here to play, learn, or contribute, OpenGames is your gateway to the world of free and open gaming.

How OpenGames Helps You Find Great Games

Finding good open source games used to be hard. You had to search GitHub manually, sift through thousands of abandoned projects, and hope the README actually explained how to install the game. We built OpenGames to solve this problem.

Our directory only includes games that actually work. We check each project for playable builds, proper licensing, and active development. We organize games into over 100 categories so you can find exactly what you want. Looking for a puzzle game written in Rust? A retro-style platformer using Godot? A multiplayer shooter that runs on Linux? Our filters make discovery simple.

We also track GitHub activity in real time. You can see which games got updates this week, which projects are gaining stars, and which developers are actively responding to issues. This helps you find games with healthy communities where you can get help or contribute code.

The Benefits of Playing Open Source Games

Open source games offer something commercial games cannot: complete transparency. When you download an open source game, you know exactly what code is running on your computer. There are no hidden trackers, no data collection, and no DRM that stops you from playing offline.

The games in our directory are truly free. Not free-to-play with microtransactions. Not free for a trial period. Actually free, with no strings attached. The open source license guarantees you can download, copy, and share these games forever.

Many open source games run on older hardware that commercial games ignore. If you have a computer from 2010, you can still play hundreds of great games from our directory. This makes gaming accessible to people who cannot afford the latest graphics cards.
