How can you detect if a website uses Spectra?

Detecting whether a website uses Spectra can be achieved by looking at the page source for specific markers and components tied to Spectra.

Below is a step-by-step guide you can follow:

  1. Open the Page Source: Right-click on the webpage and select “View Page Source” or press Ctrl+U (Windows) or Cmd+Option+U (Mac) to open the page’s source code.
  2. Search for Spectra Plugins: Use Ctrl+F (Windows) or Cmd+F (Mac) to open the search function and look for the following keyword:
    • plugins/spectra: This keyword typically denotes the usage of Spectra within the plugins folder of a website. Look for script tags like <script src="/plugins/spectra/some-script.js"></script>.
  3. Check for Spectra References in CSS and JS: Look for any links to CSS or JavaScript files that contain “spectra” in their filenames. Example: <link href="/assets/spectra-styles.css"> or <script src="/js/spectra-integration.js"></script>.
  4. Locate Spectra-Specific Classes: Inspect the HTML elements on the page to see if there are any specific classes that start with “spectra”. Right-click on an element and select “Inspect” to view the HTML structure. Look for classes such as class="spectra-component".
  5. Look for Initialization Scripts: Search for initialization scripts that indicate the website is utilizing Spectra. These may look something like <script> new Spectra(); </script>.
  6. Check for Spectra Configuration Data: Sometimes, websites will include configuration objects containing settings for Spectra. Look for JSON or JavaScript objects that mention Spectra configurations, such as const spectraConfig = { ... }.
  7. Analyze Network Requests: Open the Developer Tools (usually under F12) and check the “Network” tab while the page is loading. Look for any network requests that serve Spectra resources, which may have URLs containing “spectra” in them.
  8. Seek Spectra-Related Comments: Developers may leave comments in the HTML or JavaScript indicating the use of Spectra. Search for comments like <!-- Initialized using Spectra --> or similar notes.
