Questions about finding Nextra
- How does PageSourceSearch know a website uses Nextra?
- By the source itself: Nextra's layouts render elements with classes starting nextra-, such as nextra-nav-container and nextra-sidebar-container. PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
- Is this a complete list of websites using Nextra?
- No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 663,067 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
- How do I find websites that use Nextra together with another technology?
- Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example class="[^"]*nextra- with wp-content/plugins/ lists the WordPress sites that use Nextra.
