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

Spectra 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 July 16, 2026. The site is hosted on GitHub Pages and served through Fastly. We've detected 4 technologies on this site, covering CDN, hosting, payments, and security. The stack includes Fastly, GitHub Pages, and HSTS.

It's on one of the most common stacks we track, shared by 1,718 launches.
