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

Otter is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 17, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 months before launch. We've detected 8 technologies on this site, covering directory, security, CDN, and frameworks. The stack includes Next.js, React, and Cloudflare.

It's running the same core stack as 2,990 other launches.
