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.

We built a camera only robot vacuum for less than 300$ (Well almost) covers some of the launch checklist, with fast page loads and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 6, 2026. The site is hosted on Fastly in the United States. Our crawler found 10 technologies on this site, covering package cdn, analytics, CDN, and data api. The stack includes jQuery, Altmetric, and cdnjs.

Notably, it's on a stack we've seen on only 4 launches.
