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 18 August 2026; the live site may have changed since.
Steam Sonar scores highly overall, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Visible gaps: incomplete legal pages and incomplete email security.
Launched on Product Hunt on August 18, 2026. The site is served through Akamai. The crawl picked up 30 technologies on this site, covering data api, media handling, analytics, and video. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 5,120 launches and more locked down than the typical Product Hunt launch.
