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 2 July 2026; the live site may have changed since.

Sieve — Free Email Extractor is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 2, 2026. The site is hosted on Vercel. We've detected 7 technologies on this site, covering advertising, consent tooling, frameworks, and hosting. The stack includes Google Funding Choices, Svelte, and Carbon Ads.

It's on a stack we've seen on only 12 launches.
