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 19 August 2026; the live site may have changed since.
Online Bubble Level scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.
Launched on Hacker News on August 19, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered the day of launch. Our crawler found 7 technologies on this site, covering servers, analytics, CDN, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.
It's also on one of the most common stacks we track, shared by 1,156 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
