CSR vs SSR Render Detector is a Chrome extension that helps developers and SEO professionals visually identify Server-Side Rendered (SSR) vs Client-Side Rendered (CSR) content on any webpage.
CSR vs SSR Render Detector does NOT collect, store, transmit, or share any personal data or browsing information. There are no analytics, no tracking, and no external servers.
- The extension reads the current webpage's HTML source and compares it against the live DOM to classify elements as SSR or CSR.
- All processing happens locally in your browser. No data is ever sent to any external server.
- Detection runs when you click the icon and toggle it on. If you enable "Follow across pages" (see below), detection also resumes automatically on the next page you open.
The extension temporarily reads website content (HTML elements) solely for the purpose of SSR/CSR detection. This data is:
- Processed entirely in your browser
- Never stored or saved
- Never transmitted anywhere
- Discarded when you toggle detection off, navigate away, or close the tab
By default, the extension only runs on the current tab when you activate it. You can optionally turn on "Follow across pages" so detection stays active as you move from page to page without switching it back on each time.
- This feature is off by default and only works after you explicitly grant permission when Chrome prompts you.
- When enabled, it uses Chrome's host-access permission so the extension can re-run its local detection on the pages you visit.
- It still does not collect, store, or transmit anything — the only thing that changes is that detection re-runs automatically after you navigate.
- You can turn it off at any time from the extension's popup, which removes the access.
- activeTab: Access the current page's content only when you activate the extension.
- scripting: Inject the detection script that creates the visual overlays on the page.
- storage: Remember which detection mode is active for a tab (kept in temporary session memory only) so it can be re-applied after you navigate. No browsing data is stored.
- Host access (optional — "all sites"): Requested only if you turn on "Follow across pages," so detection can continue on the pages you visit. It is never requested unless you opt in.
This extension does not use any third-party analytics, tracking, or data collection services.
