Full Site Security Auditor
Runs 47 security, DNS and CMS checks.
Why use these instead of a crawler?
Big SEO crawlers are great, but they cost money, take time to set up, and show you hundreds of numbers at once. These extensions do one job each. Open your site, click the icon, and you get a clear answer to one question.
Because they run inside your browser, there is nothing to install on your server and nothing to configure. Some of them can even read links on pages that only show them with JavaScript.
What they have in common
- Free, with no account or activation code
- Export to Excel and PDF, ready to share with a developer or client
- Keep your data in your own browser
- The crawling tools keep working in the background and save their progress
- Clear results in plain words, not hundreds of numbers
How to install
The steps are the same for every tool, and take about a minute.
- Download the zip file with the button on this page and unzip it. You will get one folder for each tool. Install the ones you want.
- Open the extensions page. In Chrome, type
chrome://extensionsin the address bar and press Enter. In Edge useedge://extensions, in Bravebrave://extensions. - Turn on Developer mode with the switch in the top right corner.
- Click Load unpacked and choose the unzipped folder (the one that contains
manifest.json). - Pin the icon from the puzzle piece menu in your toolbar, so it is always one click away.
Developer mode only means Chrome lets you load an extension from a folder on your computer. It does not change anything else in your browser.
Questions
Are these extensions really free?
Yes. All seven are free to download and use and open source under the MIT license, with no account, no subscription and no activation code.
Do I need to be an SEO expert?
No. Each tool explains what it found in plain words and shows which pages need attention first. You can also export Excel and PDF reports to share with a developer.
Where does my data go?
Scan results and settings are saved in your own browser. The extensions do not ask you to sign in.
Which browsers are supported?
Google Chrome, and browsers built on Chromium such as Microsoft Edge and Brave.
Can I install all seven at once?
Yes. Download the all-in-one zip, unzip it, and load each folder with Load unpacked.
