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 10 April 2026; the live site may have changed since.
The Online Toolkit - Tools for Science is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on April 6, 2026. The site is hosted on Netlify, with a domain registered 8 months before launch. The crawl picked up 8 technologies on this site, covering advertising, consent tooling, DNS providers, and web fonts. The stack includes Google Funding Choices, Google Ads, and Google AdSense.
For context, it's running the same core stack as 1,570 other launches.
