SciTE vs Brackets

It's property files allow for fine tweaks of its behavior, at a global or per language / project level. These textual settings might be confusing for those used to preference dialogs, but prove to be powerful, flexible, and fine grained.

With less than 2 MB of binary on Windows, SciTE starts instantly. Plus, if you don't need all the config, syntax files, blah, there's a 678k standalone .exe version. Nothing is going to beat that for lightweight and start-up times. Stick it in a folder that is already on your PATH.

Based on the Scintilla source code editor, SciTE has some advanced features like rectangular editing, simple regular expression search and replace, code folding, etc. It allows the user to launch a compiler or interpreter, and it can also interpret the error messages, jumping at the location they point to.

Lua scripting is key to SciTE's power and flexibility. The Lua scripting language can be used to perform complex text transformations. It's relatively simple syntax and its large user-base makes it a great choice for a scripting feature.

The console window can show the result of ran commands (like build current file, reporting warnings, and errors), but also accept interactive shell commands.

SciTE works on Windows and Linux, and it also has a commercial port on MacOS.

Lexers providing folding and syntax highlighting are based on code, not on regular expressions. They support context, nesting, special rules, etc.

SciTE is written in C++, with lot of contributors, both to the core and to the numerous lexers.

Has a simple graphical user interface

Brackets will automatically refresh the browser and load the latest saved version of a file open in the browser. This works with php as well. Editing a css will even highlight the tag that's currently being worked on. However, it only works with Chrome.

Brackets is easy on memory usage and it starts up quickly.

Brackets is entirely free and open source.

The functionality of Brackets can be extended via a simple-to-use extension manager. The extension manager also has a considerable number of extensions and themes.

A feature called "Quick Edit" allows the user to select a tag in (a html file, for example) and edit the associated style without switching over to the css document. It also supports SASS and LESS pre-processors.

Brackets is being actively maintained and developed.

Hovering over colors hex codes or image paths will pop up previews of corresponding colors and images.

Brackets supports drag and drop of text, as well as multi / rectangular selection.

The editor is built using html, css, and javascript, making it extendable by any front-end developer.

You can have your cursor independently on multiple lines and so creating templates and/or editing multiple things at once is really fast and easy.

Vim-style editing is already built in the text editor.

A default extension allows for the extraction of PSD resources, such as images and styles. There's good integration for placing extracted resources into source.
