Modern Code Blocks replaces Confluence's built-in code macro with a modern editor experience. Insert code in any of 85+ languages and customize the display with syntax highlighting, line numbers, word wrap, font size, and an optional minimap. The configuration panel includes a live Monaco editor preview so you see exactly how your code will look before saving. Theme support goes beyond a simple toggle. When set to Auto, code blocks follow your Confluence color mode in real time, switching between light, dark, and high-contrast themes as you change your preferences. Manual theme overrides are also available for pages that need a consistent look regardless of reader settings. This app is ideal for engineering teams, technical writers, and anyone who regularly shares code snippets on Confluence and wants a polished, readable presentation without extra formatting effort.
