About

With focused visual tools and preprocessor support, Brackets is a modern text editor that makes it easy to design in the browser. It's crafted from the ground up for web designers and front-end developers. Brackets is a lightweight, yet powerful, modern text editor. We blend visual tools into the editor so you get the right amount of help when you want it without getting in the way of your creative process. You'll enjoy writing code in Brackets. Brackets is an open-source project, supported by an active and passionate community. It's made by other web developers like you! Instead of jumping between file tabs, Brackets lets you open a window into the code you care about most. Want to work on the CSS that applies to a specific ID? Put your mouse cursor on that ID, push Command / Ctrl+E and Brackets will show you all the CSS selectors with that ID in an inline window so you can work on your code side-by-side without any popups.

About

Koi Editor is a professional text editor for Mac, built around three principles: fast, local, and scriptable. Koi is designed for responsive editing from ordinary source files to very large documents. It includes multi-cursor editing, synchronized views, project-wide search, context-aware autocomplete, syntax highlighting for 30+ languages, code folding, file outlines, configurable themes and keybindings, and extensive editing commands. Koi requires no account, includes no telemetry, and can operate entirely offline. Configuration and keybindings are plain text, and custom editor commands can be written in Python. Optional AI features connect directly to local models through Ollama for code completion and inline assistance. Built specifically for Apple Silicon Macs, Koi combines a high-performance editing core with native macOS integration.

Pros & Cons from Real Users

Pros

  • With the help of Brackets' live preview tool, developers can observe updates to HTML, CSS, and JavaScript in real time. Testing is sped up and front-end development made easier with this live preview capability.

Cons

  • Brackets is a good tool for web programming, although its language support might not be as extensive as that of more complete integrated development environments (IDEs). Other technologies could be more adaptable for developers who work with a variety of languages.
