If it is just for cracks in the sidewalk, boiling water works.

You can use a combination of salt and white vinegar to kill weeds.

Fire weeding works. When weed just emerge and are tender, run a weed burner over them. No need to burn them, just wilt them.

Costly Roundup? Get serious. Buy the concentrate and mix your own. It's $2 a gal or $2.80 a gallon if you buy the tough weed version.
