What makes Brackets different from other web code editors?
Tools shouldn't get in your way. Instead of cluttering up your coding environment with lots of panels and icons, the Quick Edit UI in Brackets puts context-specific code and tools inline.
Brackets is very early in development, so many of the features you would expect in a code editor are missing, and some existing features might be incomplete or not as useful as you'd want. But if you like the direction it's going, please contribute!
The text editor inside Brackets is based on CodeMirror--thanks to Marijn for taking our pull requests :) See Notes on CodeMirror for info on upcoming things we're planning to contribute to CodeMirror.
