Night Viewer - Dark mode for view page source

Night Viewer is a lightweight, free Chrome extension that transforms the traditional View Page Source interface by enabling a sleek dark mode. It not only applies a visually comfortable dark theme but also beautifies the source code, making it easier to read and understand.

The extension allows users to adjust the font size within the View Page Source to suit their preference—either increasing or decreasing text size. Uniquely, Night Viewer shows both the original HTML returned from the server before JavaScript execution and the dynamically rendered DOM after JavaScript runs, offering deeper insights into how webpages are constructed. Developed by the team behind the renowned Night Eye dark mode extension, Night Viewer ensures complete privacy by operating in a serverless manner, storing only font preferences locally. For developers and curious users, it provides a stylish and functional way to explore webpage source code without sacrificing comfort or privacy.
