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

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

Launched on Hacker News on August 20, 2026. The site is hosted on Vercel, with a domain registered in 2010. The crawl picked up 12 technologies on this site, covering analytics, consent tooling, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Termly.

For context, it's running the same core stack as 200 other launches.
