Prerender Buddy Chrome extension
Use the free Chrome extension to run a quick crawler-readability check on the page currently open in your browser.
Install the extension
Add Prerender Buddy from the Chrome Web Store
What it checks
The extension sends the current public page URL to the Prerender Buddy checker and summarizes signals such as:
- whether the raw HTML exposes useful visible content
- page title and meta description
- headings and readable text
- JavaScript app-shell indicators
- crawler-readability warnings
The score appears on the extension badge so you can compare pages while browsing a website.
How to use it
- Open a public website page in Chrome.
- Select the Prerender Buddy extension from the toolbar.
- Run the page check.
- Review the score, metadata, headings, and crawler-readability notes.
- Open the full web checker when you need a more detailed comparison.
Account requirements
Basic page checks work without a Prerender Buddy account. If you choose to save a site, the extension opens the Prerender Buddy web app where signup, login, and site setup use the normal account flow.
Privacy and limits
The extension checks the active public page only when you ask it to run. It does not read passwords, form values, cookies, or private browsing history.
Results describe technical crawler-readability signals. They do not guarantee rankings, traffic, indexing, or AI mentions.
