Free WordPress Site Info Checker: Detect Version, Theme, and Plugins
Ever wondered what theme and plugins a WordPress website is using? Whether you're analyzing competitors, troubleshooting a client's site, or looking for design inspiration — knowing the technology stack behind a WordPress site is invaluable.
The WP Site Info Checker by Jayax.dev detects the WordPress version, active theme, installed plugins, hosting provider, and security configuration of any WordPress website — in seconds and completely free.
What the WP Site Info Checker Detects
1. WordPress Core
Version Detection
- Identifies the WordPress version running on the site
- Checks if the version is up-to-date or outdated

Why it matters: Outdated WordPress installations are the #1 cause of WordPress hacks. Each version has specific vulnerabilities that attackers target.
2. Theme Information
Active Theme Detection
- Theme name and author
- Theme version
- Parent/child theme relationship
- Premium vs. free theme identification

Popular Themes We Detect:
- Astra, GeneratePress, OceanWP
- Avada, Enfold, Flatsome
- Divi, Extra (Elegant Themes)
- Genesis Framework themes
- Custom themes
3. Plugin Detection
Installed Plugins
- Identifies active plugins through various detection methods
- Shows plugin names and versions where available
- Estimates total plugin count
- Flags potentially vulnerable plugins

Understanding the Results
Detection Confidence Levels
| Level | Meaning | |-------|---------| | 🟢 High | Confirmed through multiple indicators | | 🟡 Medium | Likely based on available evidence | | 🔴 Low | Possible but not confirmed |
Why Some Information May Not Be Detected
Some WordPress sites actively hide their technology stack:
- Security plugins may remove version numbers and meta tags
- Custom configurations may block detection methods
- CDN/WAF may interfere with fingerprinting
- Server-side rendering may limit client-side detection
This is actually a good security practice — sites that hide their technology stack are harder to target.
FAQ — WP Site Info Checker
Is this tool legal to use?
Yes. The tool only analyzes publicly accessible information — the same data that any web browser can see. It does not attempt to access admin panels, exploit vulnerabilities, or bypass security measures.
How accurate is the plugin detection?
Plugin detection accuracy varies:
- Popular plugins: 90%+ accuracy
- Custom/obscure plugins: 50-70% accuracy
- Plugins with active hiding: Lower accuracy
We use multiple detection methods to maximize accuracy.
Can I check non-WordPress sites?
The tool is specifically designed for WordPress. If you enter a non-WordPress URL, it will report that the site doesn't appear to be running WordPress.
How do I hide my own WordPress site from detection?
To reduce detectability:
- Remove WordPress meta tags (
remove_action('wp_head', 'wp_generator')) - Hide theme and plugin directories
- Use a security plugin that removes identifying information
- Block access to
readme.htmlandlicense.txt - Remove RSS feed version information
Can I check multiple sites at once?
Currently, the tool checks one site at a time. For bulk checking, you can run multiple scans sequentially.
