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 30 June 2026; the live site may have changed since.
Oil Manual ships with the launch fundamentals in place, with a thorough launch checklist and clean crawl signals. What needs work: no Content-Security-Policy, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 30, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 9 technologies on this site, covering analytics, CDN, consent tooling, and DNS providers. The stack includes Astro, Google, and Cloudflare.
For context, it's running the same core stack as 185 other launches and tighter on security headers than most Product Hunt launches.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |

| AI writing signals | +5 |
This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
