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 24 June 2026; the live site may have changed since.

PurchaseAtlas ships with the basics, with complete legal pages. Main gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 24, 2026. The site is hosted on Fastly in the United States. We've detected 11 technologies on this site, covering javascript library, package cdn, baas, and CDN. The stack includes cdnjs, Chart.js, and Fastly.

It's one of 79 launches on this exact stack.
