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.

Expiry Guard still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 10, 2026. The site is hosted on Firebase Hosting and served through Fastly. The crawl picked up 7 technologies on this site, covering auth, baas, CDN, and frameworks. The stack includes Flutter, Google Sign-In, and Fastly.

For context, it's one of just 7 launches we've crawled on this exact stack.
