JSVisible

What it does

Your users see one thing. Google sees another. JSVisible compares Googlebot rendering vs user browser rendering for JavaScript-heavy websites. Built for React, Next.js, Vue, and Angular developers who need to know if their content is actually visible to search engines and AI crawlers. Free tier available - no credit card required.

Probably not what you think. Most JavaScript-heavy sites have hidden SEO issues only Googlebot sees — broken meta tags, missing content, render failures. Find them in 2 minutes. We scanned linear.app — a site built by world-class engineers. Googlebot rendered everything correctly. The mobile view was a 100% match. Then we found 156 SEO issues nobody noticed. Googlebot sees the same thing as users. Identical content, perfect mobile rendering, 100% visual match. So far, so good. 156 high-priority issues. 64 orphan pages. 12 JS errors.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
