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

Online Stamp Doc ships with the basics, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt, and incomplete email security.

Launched on Product Hunt on April 27, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 2 weeks before launch. We've detected 11 technologies on this site, covering advertising, package cdn, CDN, and consent tooling. The stack includes Google Funding Choices, cdnjs, and Fastly.

It's running the same core stack as 1,758 other launches.
