If I’m coding, it’s in Coda. I have been using Coda 1 since shortly after it came out more than 5 years ago. The site you’re reading now was built entirely from scratch using Coda and Transmit.
I have never felt constrained by Coda. It is fast, reliable, fun to use, and the way it works with files makes a lot sense to me.
I agree with his reviews on Coda 2 and Diet Coda… I’ve been using them for the last couple days pretty heavily and enjoying them. I’ve actually removed Coda 1 from my Macbook so I can focus purely on using Coda 2.
