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 22 August 2026; the live site may have changed since.

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

Launched on Product Hunt on August 22, 2026. The site is hosted on Vercel, with a domain registered 9 weeks before launch. Our crawler found 9 technologies on this site, covering analytics, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Google Fonts, and HSTS.

It's also on one of the most common stacks we track, shared by 3,085 launches.
