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 8 July 2026; the live site may have changed since.

Fill AI is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 8, 2026. The site is hosted on Vercel. Our crawler found 13 technologies on this site, covering javascript library, analytics, auth, and CSS frameworks. The stack includes Google Sign-In, Tailwind CSS, and Google Search Console.

It's also on one of the most common stacks we track, shared by 2,306 launches.
