JSVisible is a JavaScript SEO scanning tool specifically designed for frameworks like React, Vue, and Next.js. It renders website pages twice with a real Chrome browser (Puppeteer), once as a regular user and once as Googlebot, to identify hidden SEO issues such as noindex tags, orphan pages, missing metadata, render failures, and JavaScript errors. It provides detailed explanations and code fixes for every issue. The tool has demonstrated its effectiveness by uncovering 569 issues on a high-quality website, proving its capability to detect hidden problems even when a site appears perfect. JSVisible is a fully developed product offering over 35 SEO checks, dual user/Googlebot rendering, error detection, and more. Users can scan up to 500 pages and access additional features like scheduled scans, team collaboration, and API access. Monetization is integrated with tiered pricing, including a Pro plan at $29/month, an Enterprise plan at $99/month, and a $99 one-time lifetime deal. The technology stack comprises Next.js, Supabase, Stripe, and other tools to keep running costs between $5–30/month. Included with the sale are the full source code, domain, npm package, social media account, and additional resources such as blog content and directory listings. Despite its readiness, the tool is effectively pre-revenue with no active customer base, making monetization an open opportunity. Growth can be driven by improving free-to-paid conversion, leveraging validated acquisition channels, and targeting SEO agencies. The founder is selling the product to move on to other projects, offering extensive documentation for a seamless transition.
