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 23 June 2026; the live site may have changed since.
Simply Invoice looks production-ready overall, 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 23, 2026. The site is hosted on Cloudflare in the United Arab Emirates, with a domain registered 2 days before launch. We've detected 13 technologies on this site, covering security, AI builders, analytics, and CDN. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.
It's a rare TanStack Start sighting, just 28 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 CSS signals | +10 |
| AI writing signals | +5 |
| Recognised AI builder signature | +100 |
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.
