Server-side Rendering (SSR) Checker
Check whether a page uses server-side rendering by loading it with different browser and crawler profiles.
About Server-side Rendering (SSR) Checker
Server-side Rendering (SSR) Checker loads a submitted URL twice — once with JavaScript disabled and once with JavaScript enabled — and displays the server-rendered and regular versions side by side. Users can compare UI and HTML with highlighted differences, select profiles including Googlebot smartphone and desktop and Chrome on Android mobile, iPhone, and Windows, and the tool follows redirects like a real browser.
The page offers sign-in with Google, Microsoft, GitHub, or a verification code to unlock unlimited checks. It runs as a web app using headless Chromium, queues checks behind other tasks, and notes that comparing while scrolling is intended for desktop devices.
