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 29 June 2026; the live site may have changed since.
Checklane is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on June 29, 2026. The site is hosted on Timeweb, with a domain registered in 2025. We've detected 10 technologies on this site, covering analytics, CSS frameworks, developer tools, and transactional email. The stack includes Tailwind CSS, Microsoft Clarity, and nginx.
It's a rare Timeweb sighting, just 19 in our data.

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 |
| AI iconography 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.
