Flax Engine vs GDevelop

Flax Engine is a 3D game engine written in C++ and C#, with visual scripting and full Editor source code available. It supports C++, C#, and visual scripting, with hot-reloading for both programming languages in the Editor. Rendering features include real-time global illumination, reflections using custom software ray tracing, and GPU lightmap baking. World-building tools cover terrain, foliage, fog, nested prefabs, level streaming, and large-world 64-bit coordinates. Multiplayer projects can use low- and high-level networking APIs. Its Online system supports services such as Steam, Xbox Live, and PlayStation Network for profiles, friends, achievements, presence, and cloud saves. Supported targets include Windows, Linux, Android, iOS, macOS, web, PlayStation 4 and 5, Xbox One and Series, and Nintendo Switch. Web support is experimental and lacks C# scripting, video playback, and some other engine features. NDA-protected platform support is excluded from the public repository. The engine is free for non-commercial or educational use; commercial releases pay a 4% royalty on earnings exceeding $250,000 per calendar quarter.

GDevelop is an open-source game engine for creating and publishing games with visual, drag-and-drop tools that do not require code. JavaScript is available for scripting. It supports web, Windows, macOS, Linux, iOS, and Android, with publishing destinations including Google Play, Steam, desktop, web, iOS, and gd.games. Built-in multiplayer services include lobbies, leaderboards, and player accounts. The Free plan costs nothing and includes multiplayer and online services, thousands of Asset Store assets, and Android and desktop publishing once per day. Paid plans include full access to the mobile app, and the Pro plan supports project sharing with teammates. Support options include community resources, professional Discord channels, commercial troubleshooting, and custom development. Education plans provide anonymous student accounts, project access, and classroom resources. Subscriptions can be billed monthly or yearly, with annual savings of up to 40%, and can be canceled at any time; access ends after the paid period.
