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 8 August 2026; the live site may have changed since.

Is Extension Safe? looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 8, 2026. The site is hosted on Timeweb. We've detected 4 technologies on this site, covering DNS providers, web fonts, hosting, and seo. The stack includes Google Fonts, Google Search Console, and Timeweb.

It's one of only 35 launches we've crawled running Timeweb.
