Wirebrowser is an Electron desktop application that provides an integrated runtime instrumentation platform for web applications, built entirely on the Chrome DevTools Protocol (CDP). In production, it acts as a unified debugger, memory inspector, network interceptor, and automation runner for JavaScript running in Chromium-based browsers. The application launches a headless or headful Chrome instance via Puppeteer-core, attaches CDP debuggers to multiple pages, and presents a rich GUI (React, Ant Design, Monaco Editor, AG Grid) through an Electron window. The architecture follows a modular event-driven design: core back-end modules (Heap, Debugger, Network, Automation) are loaded by a ModuleManager and communicate with the front-end via custom DOM events and Electron IPC. The debugger module implements a sophisticated hook system that injects user-defined JavaScript callbacks on function entry/leave/return without monkeypatching, using CDP breakpoints and a state machine to serialize asynchronous events. The heap module supports both live object search (via injected QueryObjects) and offline snapshot analysis with object similarity matching (Jaccard/Dice/SimHash) for origin tracing. Key data flows include user-defined automation scripts (Node-side or browser-side) that interact with pages through the WB.Node and WB.Browser APIs, network requests that can be intercepted and modified in real-time, and memory snapshots that are queried for structural matches across multiple snapshots (BDHS). External dependencies are heavy: Puppeteer (bundled Chrome), AG-Grid (community), Monaco Editor, Ant Design, lowdb, and several CDP-specific features that lock the tool to Chromium. The project is primarily targeted at security researchers, reverse engineers, and advanced frontend developers who need introspection beyond standard DevTools.
