Brackets is an open-source editor for web designers, developed by Adobe, with a wealth of features and a huge number of extensions, which can be installed in a few clicks, turning Brackets into a very powerful tool for web developers.
Brackets is written entirely in HTML/CSS and JavaScript. Brackets has a very clean, web-like interface which looks very good, providing a menu, a work area and a side panel. It doesn’t look cluttered at all, which is one key point the developers had in mind when designing Brackets.
