In doing a considerable amount of local web development, I often come across the need to modify (or even completely swap out) the hosts file on Mac OS X. While it is possible to do this through the terminal, there is a great little tool from Clockwise that works perfectly called Gas Mask.
- Syntax highlighting
- Simple hosts file switching
- Global hotkeys for file switching
- Automatic flushing of the local DNS cache
- Growl support
