A Burp Suite extension that brings full DOM rendering capabilities directly into Burp, enabling effective security testing of modern JavaScript-heavy applications built with frameworks like ReactJS, VueJS, Angular, and more.

Features

• Captures fully-rendered DOM after JavaScript execution
• Analyzes Single Page Applications (SPAs) built with React, Vue.js, Angular, etc.
• Integrates as a custom response tab in Burp Repeater
• Auto-render option for automatic DOM capture
• Configurable Chrome connection and rendering parameters

Requirements

• Burp Suite Professional/Community
• Chrome/Chromium browser

Installation

1. Build the extension:
