100% I recommend quiver (https://q.uiver.app) for commutative diagrams. Very simple interface, exports to TikZ.

Saved me hours in undergrad, was what everyone at Stanford used for quickly communicating ideas and typing up :)

And Quiver itself exports to LaTeX that uses the `tikz-cd` package ("cd" for "commutative diagrams"), if you'd like to use that directly.
