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 24 June 2026; the live site may have changed since.

TI 84 calculator is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 weeks before launch. The crawl picked up 7 technologies on this site, covering analytics, consent tooling, DNS providers, and hosting. The stack includes Google Funding Choices, Google Analytics, and Google Search Console.

For context, it's running the same core stack as 1,260 other launches.
