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

Sero looks production-ready overall, with a complete set of security headers. Worth fixing first: incomplete legal pages, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on August 26, 2026. The site is hosted on Google Cloud, with a domain registered in 2025. We've detected 16 technologies on this site, covering analytics, ui library, AI builders, and CSS frameworks. The stack includes Tailwind CSS, Google Analytics, and Google Cloud.

It's running the same core stack as 772 other launches and tighter on security headers than most Product Hunt launches.
