Other alternatives: pixels, minifb, softbuffer.

Sure, but none of these are true alternatives because they are missing a lot of features that libraries like GLFW or RGFW have.

(They may be good alternatives for certain use-cases)

Oh, just based on the README I assumed RGFW was more minimal than it actually is.

Minimal refers to the code itself.

GLFW's codebase is ~10MB while RGFW's is about ~300kb. But RGFW tries to support nearly everything that GLFW supports.

Yeah, my bad :)
