Overview
Your friendly side panel terminal! Learn how to diagnose DNS, SSL, and email infrastructure using simple, guided commands.
WhatHappened is your first line of defense for web infrastructure auditing. Designed as a high-performance terminal emulator that lives directly in your Chrome side-panel, WhatHappened brings POSIX-style diagnostic power to your browser. Whether you are a SecOps engineer, a Web Developer, or a curious professional, you can now audit any website without leaving your active tab. Expert Context, Not Just Raw Data The 3.x series introduces our "Expert Context" engine. Every command now includes comprehensive documentation with "WHAT IS IT?" and "REAL USE CASES" sections. We don’t just give you the results of a query; we give you the technical intelligence to make faster, more informed decisions. Our Core Pillars: Zero-Cloud Architecture: Privacy is non-negotiable. Everything—from parsing your commands to analyzing network data—runs locally in your browser’s V8 engine. No servers, no tracking, no external databases. Period. Enterprise-Grade Safety: Auditing untrusted or hostile sites requires protection. We’ve integrated industry-standard sanitization (DOMPurify) to ensure your terminal environment remains immune to script injections while you investigate. Heuristic Discovery Engine: We don't rely on static lists. WhatHappened uses a live heuristic engine to analyze CNAME chains and IP metadata, providing a ~95% accuracy rate in detecting hosting providers and infrastructure stacks on the fly. POSIX-Style Pipelines: Use the power of the command line. Chain your diagnostics using pipes (e.g., dig | grep IP) to filter and process data exactly how you need it. Key Features: Network Diagnostics: dig, host, map, propagation, dnssec. Web Infrastructure: ssl audits, stack detection, headers-check, waf discovery. Privacy & Performance: vitals monitoring, cookies auditing, throttle emulation. Sudo Privileged Mode: A simulated privilege layer to prevent accidental execution of high-impact diagnostic tools.
