on websites

WPoptic is a professional WordPress detection tool that identifies plugins and themes used on any WordPress website. With a comprehensive database of WordPress theme and plugin patterns, WPoptic delivers accurate detection results instantly and completely free of charge.

WPoptic scans the website’s HTML, script calls, style sheets, and unique plugin fingerprints. It checks these against our growing database of plugin signatures. The browser extension works instantly in your browser, so you don’t need to install anything on the target website. Or use the website scan on this website

Yes, WPoptic is completely free with no usage limitations. You can detect themes on as many WordPress websites as you need without any subscription fees or hidden costs. However, if you would like to lists of websites using a specific plugin. Then check out our lead lists

A WordPress theme controls your website’s visual design and layout. Themes determine how content is displayed, including colors, typography, page structure, and overall aesthetic. Modern themes also include functionality and customization options through theme settings and page builders.

WordPress themes control presentation and design, while plugins add functionality and features. Themes manage how content looks; plugins manage what your site can do. A site requires one active theme but can use multiple plugins simultaneously.

A child theme inherits functionality and styling from a parent theme while allowing customization without modifying the parent theme’s files. Child themes are best practice for theme customization, as they preserve modifications during parent theme updates.

Consider your site’s purpose, required functionality, responsive design, loading speed, customization options, support quality, and update frequency. Using WPoptic to analyze successful sites in your niche can reveal proven theme choices.

Absolutely. WPoptic stores every detection in a central database. This allows you to generate lists like “websites using Astra,” “websites using Hello Elementor,” or “sites running The 7 theme.” You can later filter, sort, or export these lists for prospecting, competitor research, or theme analysis.

New detections flow into WPoptic every day through the Browser extension. We update plugin and theme signatures, versions, and metadata continuously. This keeps the database fresh and ensures new or updated plugins get recognized quickly. Our database is updated each quarter. 

Most of the time, yes. Even with aggressive caching, themes still leave traces in the markup or assets. For headless WordPress or extremely custom builds, detection may be limited, but WPoptic still attempts to follow asset paths and script patterns that reveal the WordPress theme.

Yes. WPoptic supports exporting in multiple formats so you can use the data in your CRM, spreadsheets, or presentations. Perfect for agencies doing audits, theme developers researching markets, or freelancers creating reports for clients.

With the free Chrome extension, you can scan as many sites as you want. But our extension has a limiter so people don’t use it for bulk data extraction. If you need any type of WordPress list, please check out our lead-list function.
