StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 April 2026; the live site may have changed since.
Vigil AI is partway there, with a complete set of security headers. Main gaps: incomplete legal pages, no robots.txt or sitemap, and no email security records.
Launched on Product Hunt on April 28, 2026. The site is hosted on Vercel. The crawl picked up 5 technologies on this site, covering developer tools, web fonts, forms, and hosting. The stack includes Formspree, Google Fonts, and HSTS.
For context, it's on one of the most common stacks we track, shared by 2,956 launches and more locked down than the typical Product Hunt launch.
