Is OpenGL and GLUT free?

Hello all,

I just started learning OpenGL and GLUT. I wanted to know if they’re free to use? If I made a game would I have to pay for a license so I’m able to distrubute my game with OpenGL and GLUT?


Nothing to pay.

How come there’s a freeGLUT? is the orignal GLUT free too?

Free can mean 2 things when it comes to software :

  • at no $ cost
  • open source

GLUT is free but it is closed source.

Pretty much all libraries are free (free as in $)

GLUT is also quite outdated, so I would suggest FreeGLUT if you want something (exactly) like glut, or you can look at alternatives like glfw.
