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 7 August 2026; the live site may have changed since.
LettersPractice is partway there, with complete legal pages and a thorough launch checklist. What needs work: missing several security headers, no sitemap, and incomplete email security.
Launched on Hacker News on August 7, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered in 2025. The crawl picked up 12 technologies on this site, covering frameworks, javascript library, analytics, and developer tools. The stack includes Skuilder, Vue.js, and Anime.js.
For context, it's a rare Skuilder sighting, just 2 in our data.
