DebugSignal — DevTools to AI Bug Copilot

Instant DevTools-to-AI context bridge, silent runtime QA, broken link radar, and tech stack inspector for frontend developers.

DebugSignal is an on-demand runtime diagnostic assistant and developer context bridge designed for frontend engineers, software testers, and technical teams. DebugSignal monitors client web applications during active development: capturing unhandled runtime exceptions, failed API requests, broken route links, and console errors—then compiling them into clean, structured Markdown reports formatted for debugging workflows and AI coding tools. WHO IS DEBUGSIGNAL FOR? - Frontend & Full-Stack Developers: Generate structured error reports bundling complete DOM breadcrumbs, component stack traces, and application state in a single click. - QA Testers & Systems Engineers: Monitor background runtime defects without keeping DevTools open. Export ready-to-paste bug reports formatted for team issue tracking systems. - API & Backend Integrators: Instantly catch failed API calls (404, 500, CORS), inspect payload status, and diagnose client-server contract mismatches. - Technical Teams: Run deep link health scans, inspect client-side runtime environments, and export clean PDF technical health audits. CORE CAPABILITIES 1. AI Fix Prompt Autopilot - Converts cryptic runtime error traces into structured, deterministic Markdown prompts. - Automatically bundles component file paths, DOM breadcrumb interaction journeys, active frontend runtime versions, and exact error line stacks. - Paste directly into your preferred AI coding environment to diagnose issues without manual typing. 2. Silent Background QA Radar - Tracks 404/500 API calls, unhandled promise rejections, and runtime exceptions silently. - Displays a status indicator only when an actual defect occurs, eliminating console noise. 3. Deep Broken Link & Dead Anchor Scanner - Audits the full DOM in milliseconds. - Detects broken routes, empty dead anchors, and missing asset references across your active page. 4. Client Runtime & Architecture Inspector - Inspects active frontend dependencies, libraries, and application runtimes operating in your current tab. 5. Technical Bug & Audit Exporter - Export structured technical audits formatted for team issue management systems. - Generate clean, printable PDF technical audits with one click. DATA PRIVACY & CLIENT-SIDE SECURITY - Zero External Telemetry: DebugSignal executes entirely within the local Chromium sandbox memory. - Zero Cloud Logging: Source code, authentication cookies, API tokens, and network payloads are never transmitted to any remote server. - No Registration Required: Fully functional immediately upon installation. - Fully compliant with Manifest V3 enterprise security guidelines. SHORTCUTS & COMPATIBILITY - Default Panel Shortcut: Alt + Shift + D (Option + Shift + D on macOS) - AI Prompt Action: Click "Copy AI Fix Prompt" - Browser Support: Compatible with all Chromium browsers.
