Added August 20, 2026 · Last analysed August 20, 2026 · via Hacker News

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

OlumJS ships with the basics, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on August 20, 2026. The site is hosted on Vercel, with a domain registered 6 weeks before launch. We've detected 12 technologies on this site, covering AI builders, APIs, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 13,623 other launches.
