LÖVE is an open-source 2D game engine which uses the versatile Lua scripting language to create dynamic gaming experiences. It relies on OpenGL graphics and the SDL interface library to allow for cross-platform implementation and is an all-encompassing gaming environment for the development and enjoyment of 2D games.

Agar is a toolkit for graphical applications. Agar is integration-friendly, extensible, highly portable, and can use different graphics APIs such as SDL and OpenGL. Agar consists of two libraries: Agar-Core provides generic object functions and portability interfaces. Agar-GUI includes the base GUI system and a comprehensive set of standard widgets. Both are implemented in C, but are usable from other languages. When compiled with threads support, both libraries are efficiently thread-safe. The distribution also includes some more specialized libraries aimed at specific applications. Agar is free software. Its source code is freely usable and re-usable by everyone under a BSD license, which allows use in commercial applications free of charge. Agar is stable, well-maintained and has been growing organically since early 2002.

A platform independent 2d game programming framework for c programmers with least possible dependencies for easy porting and with focus on easy api calls and the requirement of commercial programmers

aedGUI is a cross-plataform, easy-to-use, non-intrusive C++ GUI library that runs on top of SDL, providing themeable widgets without learning Yet Another API.
