Everything you need to know about JSVisible

Most scans complete in 1-2 minutes. Scan time depends on your site's size (number of pages) and complexity.

Free plans can scan up to 10 pages, Pro plans up to 100 pages, and Enterprise up to 500 pages per scan.
Yes! JSVisible is specifically built for JavaScript-heavy frameworks. It renders your pages using a real Chrome browser, so it works perfectly with React, Vue, Angular, Next.js, Nuxt, Gatsby, and any other client-side or server-side rendered JavaScript framework.
Orphan pages are pages on your site with zero internal links pointing to them. Google discovers pages by following links, so orphan pages are harder to find and crawl. JSVisible's Internal Link Analysis identifies orphan pages so you can add proper internal links, improving crawlability and SEO.
