1. Key Difference: User Interface One of the main differences between Adobe Dreamweaver and Brackets is their user interface. Adobe Dreamweaver offers a more complex and feature-rich interface, with various panels, toolbars, and a wider range of options. On the other hand, Brackets provides a simpler and more minimalist interface, focusing on code editing with a single window layout.

2. Key Difference: Code Editing Both Adobe Dreamweaver and Brackets are code editors, but they differ in their approach and features. Adobe Dreamweaver offers a visual WYSIWYG editor that allows users to design web pages visually and also includes a code editor for advanced users. On the other hand, Brackets is primarily focused on code editing and provides features like syntax highlighting, autocompletion, and code folding to facilitate developers' workflow.

3. Key Difference: Extensions and Plugins Another significant difference between Adobe Dreamweaver and Brackets is their support for extensions and plugins. Adobe Dreamweaver has a wide range of built-in features and also supports a vast library of third-party extensions, allowing users to customize their workflow extensively. In contrast, Brackets has a more limited selection of extensions, but it offers a lightweight and customizable environment for developers.

4. Key Difference: Pricing and Availability Adobe Dreamweaver is a commercial product that requires a subscription or one-time purchase, making it more suitable for professional web developers and larger organizations. Brackets, on the other hand, is an open-source project released under the MIT license, which means it is free to use and can be accessed by anyone, making it more suitable for individuals, freelancers, and small teams.

5. Key Difference: Cross-Platform Support Adobe Dreamweaver is available for both Windows and macOS operating systems, providing a seamless experience across different platforms. Brackets, on the other hand, takes cross-platform support to another level by being available not only for Windows and macOS but also for Linux, making it accessible to a wider range of developers.

6. Key Difference: Learning Curve Adobe Dreamweaver, being a feature-rich and complex application, has a steeper learning curve compared to Brackets. It offers a multitude of tools and options, making it ideal for professional developers who require extensive functionality. Brackets, with its minimalist design and focused approach, has a shorter learning curve, making it more beginner-friendly and accessible to those new to web development.

In Summary, Adobe Dreamweaver offers a comprehensive and feature-rich web development environment with a complex user interface, while Brackets provides a minimalist yet powerful code editor with a simpler interface and a strong focus on customization and extensibility.
