Getting Brackets

Downloads Brackets here for Mac, Windows and Linux (Debian/Ubuntu). Brackets is built with HTML, CSS and JS, but currently runs as a desktop application in a thin native shell that can access your local files.

Brackets hasn't hit 1.0 yet, but it's getting close - so feel free to give it a spin and let us know what's missing!

Updates are released about twice a month.

The Basics

Initially, Brackets opens a default "Getting Started" project. Follow the instructions in the HTML code for a quick walkthrough of Brackets feaures.

You can open a different folder in the file tree on the left using File > Open Folder. Brackets considers this folder your "project": it acts as the scope for various search operations, and some settings are tied to the folder you have open. You can easily switch back to previous projects by clicking on root folder name in the file tree. You can also drag a folder from the OS onto the Brackets window to open it in the file tree, and drag files onto the Brackets window to open them.

Unlike other editors that show open files in tabs, Brackets has a "Working Files" list, which is displayed above the file tree. Clicking a file in the file tree just views it, but doesn't add it to the Working Files list - so you can quickly browse through different files without cluttering the list. If you make an edit, the file is automatically added to Working Files. To add a file without editing it, double-click it in the file tree.


In addition to the core features built into Brackets, there is a large and growing community of developers building extensions that add all sorts of useful functionality. You can search for and install extensions using File > Extension Manager... (or click the "plugin block" icon on the toolbar).

You can also browse the available extensions online without installing Brackets first.

Brackets Highlights

Quick Edit

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.

You open Quick Edit's inline editors by pressing Ctrl/Cmd-E when your cursor is on certain pieces of code. For example:

  • In an HTML file with the cursor inside a class or id attribute or on the tag name - Quick Edit will show you all the CSS rules in your project that match. You can edit these rules directly inline, without ever leaving the context of the HTML file.
    • When multiple rules match, navigate among them using the list on the right side (or use Alt-Up/Down).
    • To create a new CSS rule directly from the inline editor, click the New Rule button (or press Ctrl-Alt-N/Cmd-Opt-N).
  • In any file with a hex color or rgb/rgba/hsl/hsla color - Quick Edit opens an inline color picker for previewing and adjusting the color. The color picker also lists the top most-used colors from other parts of the file for quick access.
  • In a JavaScript file with the cursor on a function name - Quick Edit will show you the function's body (even if it's in a different file).
  • In a CSS/LESS/SCSS file with the cursor on a cubic-bezier() or steps() transition timing function - Quick Edit opens a graphical transition curve editor.

Quick Docs is a related feature that displays relevant documentation inline. Use Ctrl/Cmd-K to open Quick Docs:

  • In a CSS/LESS/SCSS file with the cursor on a CSS property/value - Quick Docs opens documentation from the Web Platform Docs project.

You can open multiple inline editors and docs viewers simultaneously. To close a single inline editor or docs viewer, click the "X" in the upper-left or press Escape while it has focus. To close all inline editors & docs at once, place your cursor back in the main enclosing code editor and press Escape.

Live Preview

Brackets works directly with your browser to push code edits instantly, so your browser preview is always up to date while you're coding - no page reloads needed.

There are two different ways to use Live Preview:

With no backend logic - Open an HTML file and select File > Live Preview (or click the "lightning bolt" icon). Brackets will launch Chrome and open your file in a new tab. The content is served statically from a built-in server that Brackets run - it doesn't contain any of your app's backend logic.

This mode offers the full range of Live Preview functionality:

  • Browser preview updates in real time as you type in HTML and CSS files (without reloading)
  • If you edit any other type of file, the page is auto-reloaded when you save
  • When you move the cursor around an HTML file, the corresponding element is highlighted in the browser
  • When you move the cursor around a CSS file, all elements matching the CSS rule are highlighted in the browser
  • (All cursor-driven highlighting can be disabled by unchecking View > Live Preview Highlight)

All the CSS features above also work when you're in an inline Quick Edit CSS editor.

Using your own backend - Make sure your server is already running, serving files from the same folder Brackets is editing. Choose File > Project Settings and enter whatever URL corresponds to the root folder that's open in Brackets (typically a localhost URL). Then open an HTML, PHP, ASP etc. file and launch Live Preview. Brackets will launch Chrome with the correct URL to load that page from your local server.

However, this mode disables the HTML-related features:

  • The browser won't update in real time as you type in HTML/PHP/etc. files (only CSS edits will be reflected in real time). Instead, the page is auto-reloaded when you save a HTML/PHP/etc. file.
  • Nothing is highlighted in the browser when you move the cursor around an HTML/PHP/etc. file. (But highlighting when in a CSS file still works).

Why do these limitations exist? To enable HTML live editing, Brackets needs to inject some annotations into your HTML code before the browser loads it. Normally, the built-in Brackets server does this. When using your own server instead, Brackets can't inject those annotations. Without the annotations, Brackets can't map edits and cursor positions from your source file onto the corresponding DOM nodes in the browser.

Other limitations

Live Preview currently has a few other important limitations:

  • It only works with desktop Chrome as the target browser.
  • Opening the Developer Tools in Chrome will close the live development connection.
  • Files must be inside your "project" (the root folder you currently have open in Brackets).
  • Only one HTML file can be previewed at a time. If you switch to a different HTML file in Brackets, the browser preview will switch to that new page as well.
  • Updating pauses when the HTML is syntactically invalid (e.g. after you type '<' for a new tag but before you type the closing '>'). The line number and Live Preview icon turn red in this case. Brackets will resume pushing changes to the browser when syntax becomes valid again.

Quick View

Quick View makes it easy to visualize assets and colors in your code. Just hover your mouse over a color, gradient, or image reference, and a popover will appear showing a preview. You can disable this feature in the View menu.

Other Features

Multiple Selections

Brackets supports multiple cursors, multiple selections, and rectangular selections, as well as Undo Selection and useful commands like Add Next Match to Selection. See Working with Multiple Selections for more information.


  • Indentation and tabs - To change the default indentation for the editor, use the controls on the right end of the status bar at the bottom of the window. Click the word "Spaces" or "Tab Size" to switch whether you're using spaces or tabs, and change the indentation size by clicking on the number to the right. Note that Brackets uses "soft tabs", so even if spaces are inserted, the cursor moves as if tabs are present.
  • Editor font and colors - There are no official preferences for these yet. However, there are unofficial ways to Customize your code font, and several extensions add the ability to choose different themes.

See also the Preferences section below.

Quick Open

To quickly jump to a file, press Ctrl/Cmd-Shift-O and type part of the filename. You can type abbreviations or other non-contiguous parts of the name, and Quick Open will intelligently find the best matching file.

Quick Find Definition

To quickly jump around within a file, press Ctrl/Cmd-T to see an outline view - functions in a JS file, selectors in a CSS file, etc. Similar to Quick Open, you can type parts of a name to filter the list.

Code Hints

Code hints generally pop up automatically while you're typing, but you can also manually display them with Ctrl-Space (note that this shortcut uses Ctrl even on Mac).

Code hints are provided by default in a number of places:

  • HTML - tag names, attribute names, attribute values, and & entities.
  • CSS, LESS, SCSS - all property names, and enumerated property values (those where the value is a discrete list of keywords).
    • Code hints don't yet work for shorthand properties (e.g. background), only for individual properties (e.g. background-repeat).
  • JS - variables and functions, using the Tern code intelligence engine.
    • Tern makes intelligent inferences about what properties and methods a given object contains, based on an analysis of your code. In addition to the current file, Brackets looks at other files in the same folder and any files referenced by a require() statement.
    • In cases where Brackets can't determine exactly what hints should be available, it will fall back to a list of heuristic guesses. These guesses are shown in italics.
    • JS code hints use smart matching - so you can type camel-case initials and other shorthand to filter the hint list more quickly (e.g. type "gsp" for getScrollPos).
    • You also get argument hints - while you're typing arguments to a function, an indicator above the cursor lists the expected types of the arguments. Normally this appears automatically, but you can also display it manually by pressing Ctrl-Shift-Space. (Nothing is shown if Tern is unsure where the function is defined, however).


By default, Brackets runs JSLint on JS files when you initially open them and whenever you save changes. If JSLint find problems, the results are shown in a panel at the bottom. If your file is clean, you'll see a green checkmark in the status bar instead.

JSLint is very picky about formatting. JSLint is very picky about a lot of things. You can hide the JSLint results panel by clicking the close box at the top (the status bar icon will still indicate if JSLint has found problems or not), or you can turn off JSLint completely by unchecking View > Enable JSLint.

Various extensions are available that replace JSLint with a different linting tool.

Keyboard Shortcut Cheat Sheet

Here are some keyboard shortcuts that are worth knowing. Also see the Brackets Shortcut wiki page for a more complete list of shortcuts.

Ctrl/Cmd-E Open/close the inline editor (Quick Edit).
Alt-Up/Down Arrow Switch between rules in the inline editor.
Ctrl/Cmd-K Open Quick Docs.
Ctrl-Space Bring up code hints, if applicable.
Ctrl/Cmd-Shift-O Bring up the Quick Open prompt.
Ctrl-G/Cmd-L Go to a line in the current file.
Ctrl/Cmd-T Go to a method in the current file.
Ctrl/Cmd-Shift-H Show/hide the sidebar.
Ctrl/Cmd-Alt-P Live preview.


From the Brackets user interface, you can change preferences such as whether you want "code inspection" (automatic detection of errors) turned on, or if word wrap should be on. These preferences are "user-level" which means that they apply to any file in any folder that you open. Brackets also lets you override preferences on a per-project (use the File > Open Folder command) basis. These files are particularly useful for saving configuration that is specific to a project or even some files in a project.

Some of the preferences available in these files do not have any user interface yet. To modify these preferences:

  • for user-level preferences, choose Debug > Open Preferences File
  • for project-level preferences, create a ".brackets.json" file in the root of your project

Here is a quick list of some of the settings you can change in these files:

  • jslint.options: (default undefined) An object with the default options for JSLint (see the JSLint reference for a list of these options). Options specified directly within a JS file will override this preference on a per-option basis (not automically).
  • linting.enabled: (default true) Determines if Code Inspection is on
  • useTabChar: (default false) True to use tabs instead of spaces
  • tabSize: (default 4) Number of spaces to display for tabs
  • spaceUnits: (default 4) Number of spaces to use for space-based indentation
  • wordWrap: (default true) True if word wrap is on
  • (new in 37) proxy: (default undefined) The URL of the proxy server used for extension installation (general syntax: username:password@server:port)
  • (new in 37) smartIndent: (default true) Automatically indent when creating a new block
  • (new in 37) closeTags: (default { whenOpening: true, whenClosing: true, indentTags: [] }) Sets the tag closing options. See the CodeMirror documentation
  • (new in 37) insertHintOnTab: (default false) True to insert the currently selected code hint on tab
  • (new in 37) sortDirectoriesFirst: (default false for Mac, true otherwise) True to sort the directories first in the project tree
  • (new in 37) staticserver.port: Port number that the built-in server should use for Live Preview
  • (new in 38) scrollPastEnd: (default false) True to be able to scroll beyond the end of the document
  • (new in 38) softTabs: (default true) False to turn off soft tabs behavior
  • (new in 38) closeOthers.others, closeOthers.above, closeOthers.below: (default all true) False to remove the Close Others, Close Others Above, Close Others Below items from the Working Files context menu

Here's an example:

    "spaceUnits": 4,
    "closeTags": {
        "whenOpening": false,
        "whenClosing": true
    "proxy": "",
    "path": {
        "src/thirdparty/someLibrary.js": {
            "useTabChar": true,
            "tabSize": 4,
            "linting.enabled": false
        "**.js": {
            "insertHintOnTab": true,
            "scrollPastEnd": true

With this .brackets.json file at the top of your project, your files will all default to 4 space indentation. However, src/thirdparty/someLibrary.js will be set to use tabs with 4 spaces for the tabs and linting will be turned off. Note that values for paths match fileglob rules. So for example, *.js will only match JS files in the root of the project whereas **.js will match files with the JS extension anywhere in the project.
