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 29 May 2026; the live site may have changed since.

Sinceyouarrived is largely in shape, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Visible gaps: incomplete legal pages and no email security records.

Launched on Hacker News on May 29, 2026. The site is hosted on Vercel, with a domain registered 6 weeks before launch. The crawl picked up 14 technologies on this site, covering data api, analytics, APIs, and DNS providers. The stack includes Bluesky, Cloudflare Web Analytics, and GBIF.

For context, it's on one of the most common stacks we track, shared by 2,961 launches and more locked down than the typical Hacker News launch.
