SideCanvas is a user-friendly HTML, CSS, and JavaScript editor designed for the Chrome browser, providing a seamless coding experience with an instant live preview feature. It allows developers and learners to write code in three separate tabs while observing real-time updates as they type. The tool also captures console outputs, making it easier to debug and troubleshoot code snippets directly within the editor.

This add-on is ideal for quick prototyping, learning, and testing code snippets without the need for extensive setup. Users can work in either a side panel or full-page format, with dark and light themes available for customization. SideCanvas ensures privacy by keeping all code local, requiring no account creation, and sending no data to external servers.
