This is a list of 3D and 2D game engines and frameworks that have been written in C++ and the source code is available for us to modify and\or it is supported to code our games using C++

A more optimistic homage to the slopware catalog https://alternativeto.net/lists/44427/slopware/, this list is designed to showcase projects, both FOSS and proprietary, which reject contributions from Generative AI LLM slop machines. The most pessimistic thing about this list is how short it is and how so many commonly used software solutions and websites are not included. I have to give it up to the following sites for providing references: https://codeberg.org/brib/slopfree-software-index https://github.com/melissawm/open-source-ai-contribution-policies There are a lot more projects on this list which I didn't include because they aren't on AlternativeTo (yet). I'll be adding more entries to this site (and removing those who fold to the AI overlords) on a regular basis. I'm including references, which are all first-hand declarations from the development teams for each entry to ensure items aren't included based on hearsay or conjecture. Updated 10-2-2026

This is a list of game engines, frameworks and libraries that offer a C API to program our games in pure C without C++. Worth note here, most game engines, frameworks and libraries are moving to C++ away from C, so it is highly recommended to consider C++. But in case you prefer programming in pure C then this is the options you have.
