Rendered HTML Diff

This is a diff visualization tool for HTML files that runs on Electron.
Select two HTML files and visualize the differences in the rendered text with color coding.

Features

• Select old.html and new.html via GUI
• Generate diffs against the actual text content rendered by the browser, not the HTML source code
• Generate character-level diffs and display additions/deletions with color coding
• Preview diff results immediately in an iframe
• Save diff results as HTML to any location

Color coding rules:

• Additions: green background
• Deletions: red background + strikethrough
