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

Inboxd still has work before launch. What needs work: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on April 4, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 11 weeks before launch. The crawl picked up 6 technologies on this site, covering CDN, DNS providers, email forwarding, and web fonts. The stack includes Cloudflare DNS, Cloudflare Email Routing, and Fastly.

For context, it's running the same core stack as 1,753 other launches.
