For a developer we all wear t-shirts and jeans/shorts. As one of the interviewers, I personally don't care what you wear, only if you are good. If you are worried about it, a dress shirt is more than fine.
Typical advise would be one level above the dress cod for the job, so it depends on what role you are going for.
I recommend a button up, nice pants, but no need for a tie. Again, that's just me.
