Own this Launch?

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

Agent Sessions is partway there, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on July 2, 2026. The site is hosted on Vercel, with a domain registered the day of launch. The crawl picked up 10 technologies on this site, covering javascript library, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Fonts, and HSTS.

For context, it's on one of the most common stacks we track, shared by 2,181 launches.
