See what WordPress theme any website is using. Paste a URL and this free tool identifies the active theme, detects whether it’s a child theme, and surfaces visible plugins — instantly, no account needed.
Enter any WordPress site URL to identify its active theme and plugins
Plugin detection is based on public asset paths. Some plugins may be hidden or undetectable.
How to find out what WordPress theme a website is using
The fastest way to identify a WordPress theme is to paste the site’s URL into the detector above. The tool fetches the page source, reads the asset paths WordPress leaves in every page’s HTML, and returns the theme name in seconds. No browser extension, no login, no manual source-code digging required.
If you prefer to check manually: right-click any WordPress page, choose View Page Source, and search for wp-content/themes/. The folder name that follows is the active theme’s slug — for example, wp-content/themes/astra/ means the site is running Astra.
What is a WordPress theme?
A WordPress theme controls the visual design and front-end layout of a WordPress site. It determines typography, colors, page structure, header and footer layout, and how content is displayed — without touching the underlying content or database. Themes are installed through the WordPress dashboard under Appearance → Themes, and only one theme is active at a time.
Every WordPress installation ships with a default theme. As of 2025 that’s Twenty Twenty-Five, a block theme built entirely with the Full Site Editor.
What is a child theme in WordPress?
A child theme is a theme that inherits all the design and functionality of a parent theme but lets you make customizations without modifying the parent’s files directly. When the parent theme updates, your changes survive because they live in the child theme, not in the parent.
When this detector finds two theme slugs in a site’s HTML — one referenced in the stylesheet link and one in other asset paths — it flags the active theme as a child theme and identifies the parent. A child theme badge in the results means the site owner has customized beyond what the theme’s settings panel allows.
What is the difference between a WordPress theme and a template?
A theme is the entire design system for a site — it covers every page globally. A template (or page template) is a layout variation applied to a specific page or post type within that theme. One theme can contain dozens of templates. When someone says “WordPress template” informally they often mean a theme, but technically these are different things: the theme is the container, templates are its components.
WordPress theme and plugin detector
This tool detects both the active theme and visible plugins in a single pass. Plugin detection works by reading wp-content/plugins/ paths from the page source — any plugin that loads a public-facing asset (a CSS or JavaScript file) will appear in the results. Plugins that operate entirely server-side, or sites using security tools that rewrite asset paths, may not surface all plugins.
Detected plugin slugs link directly to their WordPress.org plugin pages so you can research each one immediately.
What is a nulled WordPress theme?
A nulled theme is a premium WordPress theme that has been cracked and redistributed without a valid license. They’re typically offered as free downloads on unofficial sites. The risks are significant: nulled themes frequently contain injected malware, hidden backdoors, or spam links embedded in the code. Because they bypass the theme developer’s license validation, they also receive no updates — leaving known security vulnerabilities unpatched. Using a nulled theme on a client site puts that client’s data and reputation at risk.
If this detector identifies a premium theme on a site you’re evaluating, look it up through the legitimate ThemeForest or developer link in the results — don’t source it from an unofficial download.
Can a site hide its WordPress theme from detection?
Yes. Security plugins like Wordfence and iThemes Security can obfuscate or rewrite wp-content paths, making theme detection unreliable. Some hosts and CDN configurations (Cloudflare path rewrites, for example) also strip or alter the asset URLs that theme detection relies on. If the detector returns a “theme not found” result on a site you know is running WordPress, this is usually the reason.
Sites that hide their theme slug are not doing anything wrong — it’s a legitimate hardening step. It just means the theme can’t be identified from public HTML alone.
What is the most popular WordPress theme?
Astra is the most widely installed free WordPress theme, with over two million active installations. It’s lightweight, works with every major page builder, and has a large library of starter templates. Other consistently top-ranked free themes include Neve, OceanWP, Kadence, GeneratePress, and Blocksy. Among premium themes, Avada has been the best-selling theme on ThemeForest for over a decade.
What is the fastest WordPress theme?
Theme speed depends on what “fast” means in context. For raw page weight and Time to First Byte, GeneratePress and Kadence consistently benchmark at under 30KB of front-end CSS with no render-blocking scripts. Astra and Blocksy are close behind. Among premium themes, Flatsome (WooCommerce) and GeneratePress Premium are frequently cited for strong Core Web Vitals scores out of the box. The theme is only one factor — hosting, caching, and image optimization typically have a larger impact on measured speed than the theme choice.
What to look for when choosing a WordPress theme
The theme you pick for a client site or your own project should be evaluated on five things: load performance (check its base CSS/JS weight before adding page builder overhead), update history (abandoned themes become security liabilities), compatibility with your page builder or block editor workflow, accessibility readiness (WCAG compliance matters for public-sector and many commercial clients), and licensing clarity. For agencies building sites on behalf of clients, a theme with a clear multi-site or developer license avoids billing complications later.
FAQ
What WordPress theme is this website using? Paste the URL into the detector above. It reads the page’s HTML source and identifies the active theme from the WordPress asset paths embedded in every page.
What is a WordPress child theme? A child theme inherits everything from a parent theme but stores your customizations separately, so parent theme updates don’t overwrite your changes. The detector flags child themes in results and identifies the parent.
What is a block theme in WordPress? A block theme uses the Full Site Editor to control every part of the site — header, footer, templates — using blocks instead of PHP templates. WordPress’s default themes from Twenty Twenty-Two onward are block themes. Classic themes still use PHP template files and the Customizer.
What is a nulled WordPress theme? A nulled theme is a premium theme distributed without a valid license, usually with malicious code injected. They are unsafe to use on any live site.
Can you detect WordPress plugins with this tool? Yes. The tool surfaces any plugin that loads a public-facing asset. Server-side-only plugins and sites with obfuscated asset paths won’t show all plugins.
What is a GPL WordPress theme? GPL (General Public License) means the theme’s code is open source and can be freely used, modified, and redistributed. All themes in the WordPress.org repository are GPL. Many commercial themes are also GPL, meaning the code is technically redistributable — though this doesn’t mean support or updates transfer with it.
What is a responsive WordPress theme? A responsive theme uses CSS media queries to adapt its layout to different screen sizes. All themes in the WordPress.org repository are required to be responsive. If a theme description highlights “mobile responsive” as a selling point in 2025, treat it as baseline expectation, not a feature.
What happens when I change my WordPress theme? Your content (posts, pages, media) is unaffected. What changes: your design, widget areas, menus (which need reassigning), and any theme-specific shortcodes or custom fields that may stop rendering correctly. Always test a theme change on a staging environment before applying it to a live site.
