RenderScope: SSR vs CSR Viewer geliştiren: Sourav Dutta

🔍 What is RenderScope?

RenderScope is a developer tool designed to give you a clear, instant comparison between what a web server physically delivers (SSR — Server-Side Rendering) and what the browser renders after JavaScript runs (CSR — Client-Side Rendering).

This is the fastest way to diagnose hydration issues, SEO rendering problems, Core Web Vitals regressions, and JavaScript-dependent layout shifts — without any complex set up.



⚡ Key Features

🖥️ Side-by-Side Preview
View SSR and CSR outputs simultaneously in a clean split-pane layout — no toggling, no reloading.

📱 Responsive Device Mockups
Accurately simulate Desktop (1440px), Tablet (768px), and Mobile (414px) viewport sizes. The views auto-scale to fit your screen perfectly.

🚫 True JavaScript Isolation
The SSR pane strictly disables all JavaScript execution using iframe sandboxing — so what you see is exactly what a crawler or a user with JS disabled would see.

🔄 Refresh Button
Reload both SSR and CSR views simultaneously with a single click — no need to reload the entire page.

🌗 Dark & Light Mode
Automatically inherits your system's preferred color scheme. Toggle manually anytime from the top bar.

🛡️ Smart Header Bypass
Automatically bypasses X-Frame-Options and Content-Security-Policy headers so nearly any website can be rendered in the preview panes.

📋 Scrollbar Isolation
Injects clean CSS into loaded frames to hide native scrollbars, ensuring a distraction-free, device-authentic experience.
