Since 2006, I have maintained ebukva.com using a changing array of tools. Adobe Photoshop for Mac has been a constant, even though I started using Sketch as my primary design tool in 2013. The first HTML file was saved using TextWrangler from Bare Bone Software (before it became a trial version of BB Edit). I used and loved TextMate for a number of years thereafter. Nowadays, I use Sublime Text. I version control in Git, via iTerm. Solarized iTerm theme, diff-so-fancy, and Fira Mono make doing that a touch more elegant.
