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 10 April 2026; the live site may have changed since.

Post — Slow letters for a fast world still has work before launch. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on April 7, 2026. The site is hosted on Netlify, with a domain registered 1 week before launch. The crawl picked up 5 technologies on this site, covering DNS providers, email forwarding, web fonts, and hosting. The stack includes Google Fonts, HSTS, and Namecheap DNS.

For context, it's on one of the most common stacks we track, shared by 1,571 launches.
