Tab-based dashboard for network diagnostics with a modern UI. Network Diagnostics Dashboard is a lightweight, privacy-friendly Chrome extension that helps developers, QA engineers, performance teams, and power users troubleshoot web performance and connectivity issues fast. It gives you a focused diagnostics dashboard for the active tab so you can quickly identify what is slowing down a page, what is unstable, and what needs attention first. Key features: One-click collection of actionable page performance metrics from the active tab First Paint, First Contentful Paint, TTFB, DNS, TCP, TLS, DOMContentLoaded, and full load timing Core Web Vitals analysis with visual badges and progress indicators Performance score card for fast overall assessment Resource overview with total requests, total bytes transferred, and largest assets Full resource drill-down with filtering and sorting by type, size, and duration Waterfall chart for resource loading timeline analysis Connection diagnostics including effective connection type, RTT, downlink, and Save-Data when available Public IP and server IP lookup for quick troubleshooting context Built-in diagnostics tool to test fetch latency and status for any URL API call analysis to detect slow endpoints, large payloads, and request bottlenecks Third-party resource analysis to identify external performance impact Image optimization analysis for heavy or inefficient assets Historical performance tracking for comparing runs over time Export options for JSON, CSV, HTML snapshots, and AI reports AI-powered features: Built-in local AI-style analysis for performance triage Smart recommendations based on collected metrics and resource patterns Quick wins for common improvements Predicted impact estimates for time saved, bandwidth saved, and score improvement AI Incident Radar for likely root-cause signals such as backend latency spikes, upstream API bottlenecks, payload-heavy render paths, and main-thread interaction delays Optional advanced AI support: Users can optionally connect their own AI provider for enhanced analysis. Supported options include: OpenAI Gemini Anthropic Ollama Remote AI is optional and disabled by default. If not configured, the extension continues to work with local built-in analysis only. Why users install it: Faster troubleshooting of slow or unstable websites Clear, readable UI focused on fast triage Useful for debugging frontend, backend, API, and network bottlenecks in one place Built with Manifest V3 using Chrome scripting APIs and the Performance API No background logging of page content by default # Updates *Version 3.0.1 : Bot & Agent analysis (Session trust score and on-page agent detection) ## Privacy note: The extension is privacy-friendly by design. Collected diagnostics are used locally in the dashboard. Historical summaries are stored locally in the browser for trend tracking. Optional third-party AI analysis is only used if the user explicitly enables and configures their own provider.
