Inspiration, from Ceres Software, while not designed for the purpose,
is adequate for drawing commutative diagrams.  It's essentially a
program for drawing arrows between chunks of text, which is what you
need.  It also allows labels on the arrows, which are essential for
these diagrams.

The biggest drawback is that it doesn't do super- or subscripts,
although it may allow you to import pictures of them -- I haven't
tried.  Another problem is that it wants to put the labels on vertical
arrows on top of the arrow, but you can fernatz aroud with the
justification to avoid that.  Horizontal and diagonal arrows are no
problem.

These problems prevent me from wholeheartedly recommending the
program, but if you draw lots of diagrams, it's worth checking out.
