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.
Tandem is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.
Launched on Product Hunt on July 16, 2026. The site is hosted on Vercel. The crawl picked up 9 technologies on this site, covering javascript library, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare DNS, and Google Fonts.
For context, it's running the same core stack as 2,426 other launches.
