Comprehensive Developer Tooling Inside Your Active Tab
Inspect box models, benchmark API endpoints, audit client security, and examine runtime diagnostics without detaching your workflow.
Core Engineering Modules
A modular diagnostic cockpit designed for frontend engineers, full-stack developers, and technical auditors.
Precision CSS Inspection
Inspect exact margin, border, padding, and content layers directly over live DOM nodes. Export computed properties to clean CSS, Tailwind utility classes, or React JSX components with single-key shortcuts.
Client-Side Load Testing
Conduct concurrent HTTP stress and latency tests against local or remote APIs directly within the browser process. Measure p50, p90, and p99 response distribution curves without external server infrastructure.
DevShield Security Hygiene
Perform automated baseline audits for Content Security Policy (CSP) directives, CORS origin compliance, cookie security flags (Secure, HttpOnly, SameSite), and mixed-content vulnerabilities.
Network Protocol Analysis
Stream real-time HTTP/2 and HTTP/3 requests via the Chrome DevTools Protocol. Inspect headers, payload sizes, response timing waterfalls, and configure local response-mocking rules.
Storage & Session Management
Directly inspect and modify LocalStorage, SessionStorage, IndexedDB records, and document cookies with single-action storage purging for testing authenticated flows.
DOM State Persistence
Inject custom CSS modifications or zap obstructive DOM elements with local domain-mapped persistence. Changes remain applied automatically across document reloads.
Keyboard Shortcuts
Designed for high-efficiency navigation and rapid diagnostic extraction.
